DRAWS ATTIC OUT VENTILATION CHUTE ATTIC FLOWVENTILATION CHUTE FLOW INSULATION INSULATION CATHEDRAL CEILING S-400 STRIP VENT COOLER OUTSIDE THE COR-A-VENT SYSTEM COOLER OUTSIDE S-400 STRIP VENT A balanced vent system is one that best utilizes three natural forces: air pressure, the thermal effect and diffusion. Basically, for every square inch of ridge (exhaust) vent you must balance it with at least one square inch or more of soffit (intake) vent. COR-A-VENT ridge & soffit vent products offer: V-600 products 20 sq. in. Net Free Vent Area (NFVA)/lineal foot V-400E & X-5 products 17 sq. in. NFVA/lineal foot V-300 & Fold-A-Vent products 13.5 sq. in. NFVA/lineal foot S-400 Strip Vent line offers 10 sq. in. NFVA/lineal foot With a ridge and soffit system, cooler ventilation air will be drawn into the attic (or roof cavity if a cathedral ceiling) through the soffit/eave vents located within the positive pressure (intake) areas. It will exhaust through the vents in the negative pressure areas, at the ridge. Wind moving over the ridge literally siphons the hot/moist air out of attic. If the ridge vent were to be installed alone, then part of the ridge would become an inlet vent to relieve this draw. This could cause weather infiltration. The ridge vent must always be installed in combination with some form of soffit/eave intake vents. Do not use ridge vents with gable vents or other roof mounted vents. The Ventilation Chute, or air passageway between the soffit and the ridge must not be blocked or restricted so as to impede airflow. Once again, the ridge vent in this situation can act as intake and exhaust, causing weather infiltration. For a more attractive ridgeline, COR-A-VENT recommends installing the ridge vent to the very ends of any given ridge. A ridge that is the same height from end to end makes our vent even less noticeable. Please refer to the backside of this page for examples of typical continuous soffit vents and vent chute details.

Balanced ventilation The right proportion of venting. COR-A-VENT has promoted and taught balanced ventilation from the day we started. It s a concept all vent manufactures readily endorse. Unfortunately, that information doesn t always end up in the hands of the person designing the building or installing the vents. Balanced venting helps insure the performance you expect from ridge venting uniform, increased airflow through the roof cavity without weather infiltration. Balanced venting: An equal or greater amount of vent opening (sq. in net free vent area/nfva) in the 1 ➁ ➃ INLET (BALANCING) VENTS RIDGE VENT UNBALANCED VENTILATION AREAS 1. SKYLIGHTS 2. DORMERS 3. INTERSECTING BUILDING COMPONENTS 4. VALLEYS 5. CHIMNEYS ➃ ➂ ➄ soffit (intake) than at the ridge. For example, our V-400E products have 17 sq. in NFVA per lineal foot. To balance this, you need 2 soffit/eave/intake vents of approximately 8.5 sq. in. per lineal foot ( 1 /2 of 17 in each overhang). Balanced venting: Continuous soffit vents are recommended, especially for venting cathedral ceilings. Wherever there is ridge USE BALANCED AMOUNTS OF SOFFIT VENT TO RIDGE VENT vent above, there should be soffit/eave/intake vents on the structure below. Also, COR-A-VENT strongly recommends using of one of our V-300 products (available in 11, 8 1 /2 or 7" widths) on cathedral ceiling and hip roof applications. V-300 delivers 13.5 sq. in net free vent area. The volume of space to be vented in cathedrals is smaller. Therefore a lower profile (5/8") vent is called for to further reduce the chance for infiltration. When installing a ridge vent system, all other vent openings (except soffits) must be closed off. Figuring Your Ventilation Needs: V-400E: Square footage of building footprint X.48 = Lineal Feet V-400E needed 17 V-300: Square footage of building footprint X.48 = Lineal Feet V-300 needed 13.5 Example: 25' x 50' = 1250 Sq.F. 1250 x.48 = 600 600 17 = 35 L.F. V-400E needed The above formulas will give the amount of COR-A-VENT ridge vent needed for a 1/150 vent ratio, provided an equal or greater amount of soffit venting is used. For a 1/300 ratio, (building code minimum) use half the amount of ridge vent. Note: Code interpretation may vary. Consult your local building dept. For the best appearance, install COR-A-VENT continuously the entire length of the ridge. Typical continuous soffit vents The following NFVA values are approximate, except for COR-A-VENT S-400 strip vent. Consult the vent manufacturer or distributor for actual values for specific products. 4' MAX Continuous aluminum strip vent 8-9 sq. in. NFVA per lineal foot. 8" x 16" under eave cornice vents with maximum spacing of 4' apart gives 14 sq. in. NFVA per lineal foot. Typical Vent Chute Applications Continuous perforated panels 1' wide overhang (typical) gives 12-13 sq. in NFVA per lineal foot. COR-A-VENT s S 400 Continuous Strip Vent 10 sq. in NFVA per lineal foot. Note: Should you need any assistance in designing your ventilation system, fax or mail a sketch and information to our technical services department. COR-A-VENT will respond with recommendations for your particular building design. Typical Gable Cathedral Ceiling Knee Wall Maintaining an unrestricted air passageway between the soffit and ridge is crucial to the performance of the vent system, and must not be blocked or restricted.

Revolution Installation Instructions WRAP END FROM TOP TO UNDERSIDE OF VENT 1. Measure a 3" slot, 1½" each side of ridge centerline. This allows for a 2x ridge board or smaller. Snap chalk lines the entire length of the ridge. Cut slot with circular saw and clean out debris. Set saw depth so as not to cut roof rafters. Stop slot 12" short of any ridge end, intersecting ridge or obstruction (such as a chimney). 2. Cut clear band around roll, leaving colored band to hold all but the starter section together. Vent installs with legs down and fl at cap on top. 3. Remove backing from 1 Peel-&-Stick end cap section. Apply half of the section to end of the vent, starting with the top cap. Wrap other half of end cap down and underneath vent legs and Snow Screen to close off end of vent. 4. Beginning at end of ridge, apply vent with minimum 1¾" nails (2 coils provided in box) following NAIL HERE guides along vent cap. Only apply nails within the area between leg cavities DO NOT apply nails outside of NAIL HERE guide marks. Vent may be power nailed or hand nailed. Do not overdrive nails. Apply fi rst four nails (two on each side), then remove colored band to unroll rest of vent. Continue to apply according to marked guides. Repeat Step 3 to seal opposite end of vent. 5. For runs longer than 20 feet, additional vent rolls can be applied. Line up end of additional vent roll with previous roll by overlapping at offset lip, then apply Peel-&-Stick end cap to seal junction. Follow Step 4 to apply rest of vent. 6. Center shingle cap on vent and nail along NAIL HERE guideline. Continue applying caps until all vent is covered with ridge caps. Do not overdrive nails. Nail head should be fl ush with top of shingle, without indenting it. Pre-forming caps in cold weather helps avoid cracking. Be careful not to touch knife blade. Always cut in a direction away from yourself. Wear proper hand and eye protection. 12 Square inches Net Free Vent Area per lineal foot. 20' long x 11" wide x 5/8" thick. For use on roof pitches 3/12-16/12. Call our technical department for any special application questions. 7. For shorter runs of vent, trim areas provided every 12". Cut with utility knife, snips or saw, taking care to follow recognized manufacturers safety procedures for each. Important notes: COR-A-VENT ridge vents should always be installed with soffit/eave/intake vents of equal or greater area. All other vent openings (except soffi ts) should be closed off. The air passage way or Ventilation Chute between the inlet (soffi t/eave/intake) and the outlet (ridge) vent must not be blocked or restricted. COR-A-VENT products meet or exceed all nationally recognized building codes for ventilation. Patent pending #6,039,648 COR-A-VENT, Inc. P.O.

Note: MAXIMUM 1/2" cap overhang required for valve (AWF) to close properly. COR-A-VENT has the answer for stopping all forms of weather infiltration with the X-5 ridge vent: The Complete Solution superior ventilation performance and the ability to stop rain and snow infiltration cold even in weather extremes. X-5 employs dual protection to stop infiltration. First is the AWF the active weather foil, a specially designed, wind-activated, weather impenetrable valve permanently attached to the bottom layer of our X-5 vent material. The AWF will stop wind driven rain from penetrating your roof cavity. Second is the enhanced snow screen, an air-permeable filter that keeps out snow, even at low wind speeds, while still allowing hot, moist air to flow out of the attic.

Specify COR-A-VENT Enhanced X-5 for your next project! X-5 11 & NEW 8 1 /2 ENHANCED RIDGE CAP How does the AWF work? We ve engineered the valve to close at 10 MPH (± 2 MPH). The leading (windward) edge of the AWF, which is shaped like an airfoil, catches the wind blowing at it, whether directly or at an angle, and snaps shut. Meanwhile, on the downwind (leeward) side, the vent remains open and continues to exhaust hot, moist air from the attic. Below 10 MPH, the valve opens completely for positive ventilation from both sides of the vent. The AWF effectively blocks weather from entering through the vent s flutes. Dade County acceptance 1 and our own in house rain tests confirm this. The harder the wind blows, the tighter the AWF seals. How long will the AWF last? Developed from a special formulation of Reemay non-woven with a UV inhibited proprietary coating, it s guaranteed to last. Tested to the same standards as composition shingles, the AWF fabric was subjected to a 5000-hour exposure test from a Xenon Arc weatherometer. That s the equivalent of 25 years exposure to south Florida or Death Valley sun. The results no significant embrittlement or degradation. X-5 is made from a special 4mm sheet of extruded PP. This means less restriction and more airflow. At the same time, it has 17 sq. inches of NFVA (Net Free Vent Area) per lineal foot, which exceeds all national building code requirements. X-5 will work with shingle, metal, tile and cedar roofs and is also a perfect Roof-To-Wall vent. X-5 is available in 11'' and 8 1 /2'' widths and is packaged 9 four foot pieces per box. When performance counts count on X-5. From COR-A-VENT continuing our tradition as The Leader In Innovative Rooftop Ventilation. COR-A-VENT ridge vents must be installed with an equal or greater amount of soffit or intake ventilation to achieve optimal results.

Installation is a breeze. V-300 & FAV-20 are power nailable and go on fast and straight they won t compress or hump like other low profile products. Fold-A-Vent is the perfect 20' solution. It is formed into 5 4' sections. The folds relax as the sections are extended, so the vent goes on flat and smooth. While nailing the first section, our exclusive Yellow Starter Band keeps the remaining 4 sections together. Install with your power nailer and standard 1 1 /2" coil nails. The unique routed center slot allows you to center the vent on the ridge by sighting down it. No need to snap chalk lines. The flexible center hinge allows easy alignment on roofs up to 16/12 pitch. Unlike rolled products, the FAV-20 bundle stays put on the ridge while you install it you won t end up chasing it down the roof or picking it up off the ground. Corrugated rolled vents look nice in the package, but wait until you try to unroll them! They have a built-in curl. That s because the vent is rolled into a package while the plastic is still warm. Roll it out and it wants to come right back. Installation is tougher and you re left with a series of humps to flatten out.

Balanced ventilation The right proportion of venting. COR-A-VENT has promoted and taught balanced ventilation from the day we started. It s a concept all vent manufacturers readily endorse. Unfortunately, that information doesn t always end up in the hands of the person designing the building or installing the vents. Balanced venting helps ensure the performance you expect from ridge venting uniform, increased airflow through the roof cavity without weather infiltration. Balanced Venting: An equal or greater amount of vent opening (sq. in. net free vent area/nfva) in the soffit (intake) than at the ridge. For example, our V-300 & FAV-20 products have 13.5 sq. in. NFVA per lineal foot. To balance this, you need 2 soffit/eave/intake vents of at least 6.75 sq. in. per lineal foot. Balanced Venting: Continuous soffit vents are recommended, especially for venting cathedral ceilings. Wherever there is ridge vent above, there should be soffit/eave/intake vents on the structure below. USE BALANCED AMOUNTS OF SOFFIT VENT TO RIDGE VENT Also, COR-A-VENT strongly recommends using one of our V-300 or FAV-20 products (available in 11", 8 1 /2" or 7" widths) on cathedral ceiling and hip roof applications. V-300 & FAV-20 deliver 13.5 sq. in. net free vent area. Because the volume of space to be vented in cathedrals is smaller, a lower profile ( 5 /8") vent is needed to further reduce the chance for infiltration. When installing a ridge vent system, all other vent openings (except soffits) must be closed off. 1. Measure a 3" slot, 1 1 /2" each side of ridge centerline. This allows for a 2x ridge board or smaller. Snap chalk lines the entire length of the ridge. Cut slot with a circular saw and clean out debris. Set saw depth so as not to cut roof rafters. Stop the slot 12" short of any ridge end, intersecting ridge or obstruction (such as a chimney). 2. Cut the 3 clear bands leaving the colored band to hold all but the starter section together. Turn the vent bundle upside down to expose the underneath side of the starter section end. Follow steps 3 4 to create its own Folded End Cap. If Architectural Shingles, Shakes or roofing with an irregular surface is used, apply a bead of caulk to roof deck before installing vent. This will seal any gaps that could allow weather penetration under the vent. A B 3. Use a utility knife to cut out a V shaped notch from the centerline approximately 1 3 /4" in from edge and remove loose material (A). Cut through the bottom 3 layers of the vent as pictured (B) (located approx. 1 3 /4" from & parallel to the end). Remove loose pieces. Be careful not to cut into top layer. A B C 4. Fold flap under and secure with a 2" roofing nail. This allows the nail to penetrate an extra layer of vent material (inset). Align starter end 1 /2" in from edge of roof, and centered on ridge. Be sure to caulk between bottom edge of vent and roof. Nail the starter section at points A, B & C, 2" up from edge. For the best appearance, install V-300 & FAV-20 products continuously the entire length of the ridge. Figuring Your Ventilation Needs: V-300 & FAV-20 have 13.5 sq. in. NFVA/lineal foot. V-300: Square footage of building footprint X.48 = Lineal Feet V-300 or FAV-20 13.5 or FAV-20 needed Example: 24' x 70' = 1,680 Sq.F. 1,680 x.48 = 806 806 13.5 = 60 L.F. V-300 or FAV-20 needed The above formulas will give the amount of COR-A-VENT ridge vent needed for a 1/150 vent ratio, provided an equal or greater amount of soffit venting is used. For a 1/300 ratio, (building code minimum) use half the amount of ridge vent. Note: Code interpretation may vary. Consult your local building dept. Note: Should you need any assistance in designing your ventilation system, fax or mail a sketch and information to our technical services department. COR-A-VENT will respond with recommendations for your particular building design. 5. Continue applying FAV 20 by walking out remaining sections. Pull firmly to fully extend, center vent on ridge and nail other end down. Make sure vent matches roof pitch before nailing both sides in place. If necessary add FAV 20 until entire ridge is covered. Use a utility knife to cut last section to length. Fold end to finish (steps 3 4). Caulk between bottom edge of vent and roof. 6. Continue to tack nail both sides of entire length of vent. Use nail pattern shown in step 4. Center shingle cap on vent and nail. Continue nailing until all vent is covered with ridge caps. Be careful not to overdrive nail. Nail head should be flush with top of shingle, without indenting it. Pre-forming caps in cold weather helps avoid cracking.

COR-A-VENT Simple Solutions for all Your Eave Venting Details. The science of a good ridge and soffit vent system depends upon the equalization or balance of its two components the soffit/eave (intake) air and the ridge (exhaust) air. This principle of good venting practice works well with most traditional roof designs. However, many contemporary house and roof designs are limited in how well they can be naturally ventilated. This is a result of restriction in the amount of, or placement of critical intake ventilation. In the interest of modern architecture and good ventilation practices, COR-A-VENT has developed various unique soffit venting applications using our S-400 Strip Vent. All ridge vents, work best with soffit/eave (intake) vents. For the top performance, place the intake vents low on the structure, typically at the overhangs. With new construction or when re-roofing, all other attic exhaust vents such as gable-end, roof, or turbine vents should either be blocked off or removed. The stack effect (rising warmer air) is enhanced and thus maximum updraft (ventilation) is obtained when no other opening(s) can distort the air pattern between the intake and the exhaust vents. * Net Free Vent Area S-400 STRIP VENT 2 x 2 FIRING STRIPS @ O.C. - RAFTERS CONTINUOUS WATERPROOFING MEMBRANE 2" -WAY 2 x 2 INSULATION RAILING 2 x 6 ROOF RAFTER V-400E RIDGE VENT FLOW FLOW FLOW RIGID FOAM INSULATION ORIGINAL SHEATHING Cold Roof Application RIDGE CAP S-400 Soffit/Eave Vents S-400 STRIP VENT FLOW INSULATION RAFTER VENTILATION CHUTE There really are as many ways to install S-400 Strip Vent as there are eave construction details 1" x 11/2" x 4' cross section gives you maximum soffit/eave ventilation in a minimum space 10 sq. in.

Standing Seam. This is becoming the preferred roofing system for builders of low-rise commercial, industrial and institutional buildings. More than 50% of these types of structures erected in the past several years have standing seam roofs and more than 1 billion square feet of standing seam metal roofing has been installed. This roof-style is designed to be weather-tight, with a clip-fastened system beneath the steel panels to cut down on roof penetrations. Paired up with COR-A-VENT ridge vents, it s a beautiful roof that will last. Profile. Also known as screw down roofing, this system is durable, lightweight and relatively inexpensive compared to other types of metal roofing and is installed over and fastened directly to the decking underneath. Profile panel is widely used with industrial and agricultural structures like garages and utility buildings, or horse and animal barns. COR-A-VENT is a perfect match for this investment the one on the roof and everything underneath it. Metal Shake. With the look of shingle and the durability of metal, this alternative to typical residential roofing has plenty of options. Choose from metal shakes that resemble cedar wood or tile, or stone-coated products that resemble asphalt shingles, like the inset photo of stone-coated shingles from COR-A-VENT customer Gerard Roofing Technologies. COR-A-VENT comes in a variety of widths to match the cap sizes of today s popular metal shake roofs. *Crush test results of 7,653 PSF (# S per square foot) per RADCO Test Report RAD-2376 Purlin Vent.

SPACER FOR METAL ROOFING OVER ASPHALT SHINGLES

Introducing COR-A-VENT s Latest Soffit Vent Innovation A 22 1 /2 Eave Vent Designed to Fit Between the Rafters Providing soffit ventilation for openrafter construction has long been a headache for many builders. The options have been few, consisting mainly of a couple of screened-over holes in the blocking or a few metal grates every two or three rafter bays that don t provide nearly enough ventilation and, quite honestly, don t look very good. But COR-A-VENT has the answer with its newest product, Raft-A-Vent, a 22.5" long vent strip designed to fit between the rafters, on top of the blocking. Raft-A-Vent is the ideal product for this situation. At only one inch thick, Raft-A-Vent will virtually disappear under the eave, but still provides 18.75" of Net Free Vent Area per piece and is designed to run continuously in every rafter bay* to provide the superior intake ventilation you need for a balanced vent system. Good ventilation helps reduce moisture buildup and the possibility of mold growth. For an unmatched system, pair Raft-A-Vent up with any one of COR-A-VENT s ridge vents, like V-300 8 1 /2" or FAV-20 8 1 /2", both UL Class A fire rated products. *See the back of this flyer or go to cor-a-vent.com for more information about using COR-A-VENT ridge and soffit ventilation products in areas that require more stringent design of roof diaphragms in accordance with IBC requirements for wind and/or earthquake loading. Raft-A-Vent is available in either white or black. You can power-nail or screw down Raft-A-Vent and pre-attach to the blocking for fast installation!

S-400 Strip Vent: The original, continuous soffit venting solution is still the best choice for venting overhangs and eaves and once architects find out about it, they spec it on every job!

COR-A-VENT Roof-2-Wall Installation Instructions. One person can easily install the handy four-foot Roof-2-Wall sections. All you need is a hammer, circular saw, chalk line, utility knife, tape measure and a caulking gun. These instructions are typical for a standard shingle roof application. Check our web site (www.cor-a-vent.com) or call our technical dept. for advice on your specialized application, or send us a print and we ll mark up where and how to vent it. Typical Counter Flashing (This flashing not provided in Roof-2-Wall kit.) DO NOT cut slot within 6" of any end point Cut 1" slot Add 3/8" bead of flexible caulk beneath & on top of vent Close ends with EC-400 Roof-2-Wall End Cap 1. Start by cutting 1" wide clear slot in roof deck at or near the top. Stop slot no less than 6" from the ends of the roof section to be ventilated. In areas that have seismic requirements, 1" holes may be drilled. Spacing to be determined by local building officials. 2. Apply 3 /8" bead of flexible caulk (NOT roofing cement) beneath Roof-2-Wall Vent pcs. and nail down with 2 1 /2" nails provided*. Run vent at least 6" past slot in decking and close off ends with EC-400 Roof-2-Wall End Caps provided. Use a flexible caulk to seal all seams, then run another 3 /8" bead of flexible caulk along the top of all vent pcs. IMPORTANT For AWF to close properly, roof covering must not overlap edge of vent by more than 1 /2". Caulk all flashing seams IMPORTANT: DO NOT overlap edge of vent by more than 1 /2" See note below 1/2" MAXIMUM OVERHANG ON CAP CLOSED OPEN 3. Use Roof-2-Wall flashing provided to cover vent, up onto wall. Nail flashing securely to the wall and overlap flashing with housewrap or felt paper/water-proof membrane. 4. Cap or cover Roof-2-Wall assembly with shingle tabs or heavygauge/decorative metal cap. Be sure to caulk all ends and joints to ensure a water-tight installation. A minimum 3/12 roof pitch is required for Roof-2-Wall application. NOTE: Installer is responsible for sealing ends of vent for each specific application. Due to the wide variety of material choices and possible installation options, it is the installer s responsibility to seal the vent assembly s ends with appropriate method and materials to prevent weather infiltration. 2006 COR-A-VENT, Inc. 10/11 Roof-2-Wall Flier * Be sure to use nails long enough to penetrate vent and roof deck. Heavyweight, architectural and re-roof installations may require a longer nail than the 2 1 /2" ones provided. COR-A-VENT, INC. P.O.

COR-A-VENT Installation and Information Guide. Easy Installation: One person can easily install the handy four-foot COR-A-VENT sections. All you need is a hammer, circular saw, chalk line, utility knife, tape measure and a caulking gun. Here s an installation overview for a standard pitch* gable roof application: Important close off exposed center openings at both ridge ends to prevent infiltration. 1. Measure a 3" slot, 1 1 /2" each side of ridge centerline. This allows for a 2x ridge board or smaller. Snap chalk lines the entire length of the ridge. Cut slot with a circular saw and clean out debris. Set saw depth so as not to cut roof rafters. Stop the slot 12" short of any ridge end, intersecting ridge or obstruction (such as a chimney). If Architectural Shingles, Shakes or roofing with an irregular surface is used, apply a bead of caulk to roof deck before installing vent. This will seal any gaps that could allow weather penetration under the vent. 2. Nail one shingle cap at each end of the ridge, as with conventional application. Slide end cap (E.C.-400) over exposed end on first and last sections of vent, or use the Folded End Cap Technique shown on back page of this brochure. Center first vent piece on end of ridge and nail through end cap and vent, keeping end of vent 1 /2" from end of roof. Continue to tack nail first vent piece. Place nails 1 /2" from ends, and 2" up from edge, 3 nails to a side. Repeat this step for starter vent piece at the other end of the ridge. 2" 3. Continue applying COR-A-VENT, working from ends to middle. This technique helps remove any dips or sag in the ridge. Align center with previous pieces, making sure vent matches roof pitch before nailing. Continue nailing until entire ridge is covered. Use a utility knife to cut last piece to length. Caulk where bottom edge of end caps rest on roof. 4. Center shingle cap on vent and nail. Nail line for cap shingles is to be 2" 2 1 /2" up from edge. Continue nailing until all vent is covered with ridge caps. Be careful not to overdrive nail. Nail head should be flush with top of shingle, without indenting it. Pre-forming caps in cold weather helps avoid cracking. Be sure to use fasteners** long enough to penetrate vent and roof deck when nailing the vent and ridge cap on. Heavyweight, architectural and re-roof installations require a longer nail than the standard installation. In high wind areas, use a washer headed nail to prevent shingle cap blow off. Or, apply a 1 /4" to 3 /8" bead of roof cement between the ridge caps, 3 /4" up from the bottom edge of shingles parallel to ridge. COR-A-VENT Ridge Vents are sized for residential and light commercial buildings up to 60 feet wide. Please call COR-A-VENT before using our ridge vents on buildings wider than 60 feet. *Standard applications V-300 or V-600 3/12-16/12 pitch. For steeper pitch/wide ridge beam applications see complete installation sheet or see us on the web at www.cor-a-vent.com. **Nail requirements for standard vent and ridge cap installation: V-600-2 1 /2" roofing nail, V-300-1 1 /2" (with 3 tab shingles installed on new construction or after complete roof tear off).

Hip Installation Instructions If the ridge length is too short to install the recommended amount of ventilation, COR-A-VENT V-300E, FAV-20E (Fold-A-Vent ), V-400E, or X-5 may be installed in equal lengths on the upper half of the hips. These instructions can be used for most shingle, shake or slate applications. If jack rafters are 16" on center, cut the slot per our ridge installation instructions. If jack rafters are 24" on center, blocking may be needed to prevent the roof sheathing from sagging. Cut 2" x 4" blocks 8" long, and using 16-penny nails, nail blocks between jack rafters and flush with bottom of roof sheathing. Cut the slot per our ridge installation instructions. The blocks will provide support for the roof sheathing. Nail roof sheathing to blocks with 8-penny nails. See Fig. A below. Note: When using blocking, allow for a loss of 25% in ventilation due to the blocks. The slot normally does not need to be cut more than half way down the hips for open attic roofs. The vent may be run all the way down to the end of the roof for appearance reasons, BUT DO NOT CUT A SLOT UNDER IT! This will insure that the air is drawn in from the soffit inlet vents and exhausted out through the ridge and/or hip vents. If it is an ALL cathedral ceiling roof then the slot must not be cut any closer than 3 feet up from the outside wall of the building. This will prevent any ice build up from leaking back into the building. In areas that receive heavy snowfall, the slot should stop 6 feet up from the outside wall of the house. The vent may be run all the way down to the end of the roof for appearance reasons, BUT DO NOT CUT A SLOT UNDER IT! See Fig. B below for details on how to cut the vent where the hips and ridge come together. The vent can be cut with a utility knife. Caulk all joints with black silicon caulking. Also, caulk end joints on the vent coming up the hip. Using the 20-foot FAV-20E (Fold-A-Vent) will eliminate most joints on the hip itself. (See main drawing below.) If 3 in 1 shingles are used, run a 3 /8" bead of silicon caulking down each side of the slot, centered on the nailing surface of the vent. This will insure that the vent is sealed down across the shingle courses and prevent water from weeping in under the vent. If Heavy Weight Shingles, Shakes, Slate or Tiles are used: see Fig. C below for a detail on how to install a batten strip to provide a level surface for the vent to sit on. Batten strips need to be as thick as the thickest point of the roofing. There MUST NOT BE ANY GAPS UNDER THE VENT or water may leak in. 3/4" 3/4" 5/8" 3/4" 1" 5/8" End Views COR-A-VENT RIDGE VENTS W/ENHANCED SNOW SCREEN END VIEWS TYPICAL 3/4" 3/4" 1" 5/8" 5/8" 5 1/2" 4 1/4" 8 1/2" 4 1/4" A B A 1 3/4 " 1 3/4" V-400E 8 1/2" 17 sq. in.

A 2" V-600 1 3 /4" V-300 STEP 2: Fold Over Flap "A" 90 On Perforated Line. A B STEP 3: Fold Over Flap "B" 90 On Perforated Line. 1. Turn vent piece (V-300 shown) over so routed slot is facing up. Use utility knife to cut out a "V" shaped notch in one end of vent. 2. Measure 1 3 /4" from end of vent and make a parallel cut through bottom 3 layers. For V-600, measure 2" from end and cut through bottom 5 layers. Remove loose pieces. Be careful not to cut off top layer!! Folded End Cap B Front Side 3. Fold end flap under and secure with a roofing nail 2" for V-300 or 2 1 /2" for V-600. This allows for the nail to penetrate an extra layer of vent material. 4. Nail vent pieces to roof per instructions above. Be sure to caulk between bottom edge of vent and roof at both ends of the ridge. End Cap Reversed With Front Side Out, Ready For Application To End Of Vent. Be careful not to touch knife blade. Always cut in a direction away from yourself. Wear proper hand and eye protection. For the best appearance, install COR-A-VENT continuously the entire length of the ridge. Figuring Your Ventilation Needs: V-600 = 20 Sq. inches NFVA/lineal foot. V-300 = 13.5 Sq. inches NFVA/lineal foot. USE BALANCED AMOUNTS OF SOFFIT VENT TO RIDGE VENT V-600: Square footage of building footprint X.48 = Lineal Feet V-600 needed 20 V-300: Square footage of building footprint X.48 = Lineal Feet V-300 needed 13.5 Example: 25' x 50' = 1250 Sq.F. 1250 x.48 = 600 600 20 = 30 L.F. V-600 needed The above formulas will give the amount of COR-A-VENT ridge vent needed for a 1/150 vent ratio, provided an equal or greater amount of soffit venting is used. For a 1/300 ratio, (building code minimum) use half the amount of ridge vent. Note: Code interpretation may vary. Consult your local building dept. Balanced Ventilation is not only having an equal amount of ridge and soffit vents in net free inches, but having the soffit and ridge vents balance each other on the structure. Wherever there is ridge vent above, there should be soffit/eave/intake vents on the structure below. Important notes: COR-A-VENT ridge vents should always be installed with soffit/eave/intake vents of equal or greater area. All other vent openings (except soffits) should be closed off. The air passage way or Ventilation Chute between the inlet (soffit/eave/intake) and the outlet (ridge) vent must not be blocked or restricted.
