3 Versa-Span Flashings and Details Guide Notes to Designer/Installer Taylor Commercial Products is providing the following details as an aid in design. The details in this guide are not inclusive to all design situations. The designer/installer is responsible for modifications and should take into consideration all aspects of the project including climate conditions, such as, snow and wind, as well as, building code requirements, building design, building usage and maintenance requirements. Installation should be performed only by qualified installers familiar with metal roofing systems and industry standards. For details not shown in this guide, refer to the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) architectural sheet metal manual for proper design. The Standard gauge for all products in this guide is 24 gauge and the standard finish is Kynar 500 /Hylar We recommend specifying all flashings be the same gauge, color, and finish as the panels to insure long-term durability and color match. Substrates Details in the manual are all shown over solid substrate. Versa-Span can be used over spaced purlins. For solid substrate, Taylor Commercial Products recommends 5/8 plywood or metal decking. Underlayments Minimum underlayment requirements are 30 lb. ASTM rated felt, a synthetic underlayment with Class A and ASTM UV protection technology or a high temperature self-adhering rubberized membrane. When choosing the underlayment, consider the roof slope, roof design, roof panel, and the climate. Drag Load Requirements All panels must be pinned at the top to resist the drag load caused by snow loads, live loads, and the weight of the panel. Drag load is a function of roof slope, actual load and length of panels. Contact Taylor Commercial Products for specific drag load requirements. 2 Taylor Commercial Products - Phone: or ~ Fax: ~

4 Versa-Span Flashings and Details Guide Ventilation/Insulation It is the responsibility of the designer to determine the material types needed to control condensation and to insulate and ventilate the roof system. Applications over rigid insulation may require blocking for solid attachment and framing the perimeter for installation of perimeter flashings. Oil Canning Flat metal surfaces will display waviness commonly referred to as oil canning. Oil canning is caused by a variety of conditions: Steel mill tolerances, variations in or uneven substrates and roofing underlayments. Oil canning is a characteristic of metal roofing, not a defect and is not a cause for rejection. Taylor Commercial Products offers Versa-Span with striations or accent ribs to help minimize oil canning. Thermal Movement The Panels and the flashings must be allowed to expand and contract, especially with longer length panels. The panel may need to have a slight gap where the panel hooks the offset cleat to allow for thermal movement of the panels. Snow Design The following details do not address all conditions for snow environments. Consult with the designers, engineers, and others for acceptable details to accommodate your project and climate conditions. When possible, gutters, valleys, pitch changes or other penetrations should be minimized in snow areas. All roof penetrations should be located as close to the ridge or top of roof. Snow country requires special designs for valleys to accommodate accumulation of snow and ice from uphill panels. Roof design should be considered in snow areas. Roof design should help resist the melting and freezing of snow and ice. A fit for purpose roof design has the greatest impact on maintaining a damage free roof system in snow areas. Please contact a Taylor Commercial Products representative for assistance in detail designs and appropriate panel selection for specific climate and building conditions. 3 Taylor Commercial Products - Phone: or ~ Fax: ~

5 Versa-Span Flashings and Details Guide Handling / Storage & Safety Handle materials with care when off-loading or moving materials to avoid damage to panels or flashings. Long panels may require two or more pick-up points, properly spaced to avoid damaging panels. Plan ahead; contact Taylor Commercial Products for recommendations on handling/hoisting long panels. Store the panels, flashings and accessories in a dry, well ventilated area, off the ground. If covering, allow ventilation around panels. Elevate one end of bundle to allow drainage of wet materials. Wear clean, soft-soled shoes when walking on roofing panels to avoid damage to the painted finish. Take care that sand, gravel, dirt, etc. sticking to your shoes is not carried onto the roof, scratching or otherwise damaging the finish on the roofing material. Walking on asphalt impregnated felt paper, especially on a hot day, can cause the asphalt to stick to your shoes and be tracked on to the roofing material. Take care when painting to avoid getting over spray on the roofing material. Remember that wind can carry paint particles some distance. Over spray can cause the finish of the roofing material to look dull and may void your warranty. Secure materials, especially when leaving the site, on the ground or roof to prevent winds from moving the materials. Wind-blown materials may cause damage to the material, property or persons. Always use proper safety equipment and attire to minimize risk of cuts or other injuries. Do not walk on panels that have not been completely installed. Do not walk on major ribs of panels. Metal roofs that are wet or dusty can be extremely slippery. Wear soft soled shoes and a safety harness to minimize risk of falling. Avoid installing metal panels in windy conditions. Safety considerations are the responsibility of the installer and his crew. Be sure to use common sense and generally accepted safety practices when installing roofing materials. 4 Taylor Commercial Products - Phone: or ~ Fax: ~

35 Q.E.D. Inc. / QEDLAB: AAMA Accredited Laboratory & Field Testing Agency Project ID: # 2086 Ref: Taylor Metal DATE: Purpose The purpose of the conducted tests was to evaluate the performance of Taylor Metal s Versa Span line of roof panels. The tests performed enable evaluation of the roof panel s resistance to air infiltration, water penetration and provided valuable information regarding the panels structural performance. 2 Test Specimen Manufacturer: Taylor Metal Dimensions: 156 x 24 GA Panel: 17 wide Support: Steel purlins with 5 oc. span 3 Test Apparatus Chamber: Vacuum (Air and Water tests), Positive (Structural) Differential Pressure Measurement: Electronic pressure transducers w/ 25 WC capacity Air Flow Measurement: Laminar Flow Element Deflection Measurement: String potentiometers The test apparatus was constructed by embedding six, 2 inch by 4 inch beams between the existing perimeter of the specimen and then securing four OSB panels to enclose the chamber. As seen below, the OSB panels were cut with viewing windows such that the ability to detect water penetration remained. The windows were sealed throughout the duration of the tests and then removed to allow for visible inspection of the specimen. The seams of the test chamber were sealed using a structural silicone, ensuring that the chamber remained as air and water tight as possible. A gutter system was placed at one end of the specimen to allow for controlled ponding of the product during water testing. This was accomplished by creating panel width drain slots at.5 above the surface of the specimen. The lengths of the specimen were placed in a bed of sealant and then fastened to an on end 2 inch by 4 inch beam. The photographs below show the apparatus used to test the Versa Span metal roof specimen. Fully Accredited by AAMA The American Architectural Manufacturers Association Q.E.D.

Inc. / QEDLAB: AAMA Accredited Laboratory & Field Testing Agency Project ID: # 2086 Ref: Taylor Metal DATE: Figure 1 Apparatus used to test the Versa Span metal roof specimen 4 Air Infiltration 4.1 Theory of Procedure ASTM E provides a method for determining the rate at which air flows through a product when it is introduced to a difference in air pressure. 4.2 Results Air was exhausted from the test chamber at a rate enabling pressure differences of 1.57 psf, 6.24 psf and 12 psf. At all pressures, the air flow through the entire system was measured using a laminar flow element. The measured value was recorded and then used in correlation with the air flow acquired when the chamber was sealed to inhibit all possible air flow through the specimen itself. The photos below depict the pressure and airflow measurements garnered during testing. Fully Accredited by AAMA The American Architectural Manufacturers Association Q.E.D.

38 Q.E.D. Inc. / QEDLAB: AAMA Accredited Laboratory & Field Testing Agency Project ID: # 2086 Ref: Taylor Metal DATE: Water Penetration 5.1 Theory of Procedure ASTM E provides a method for determining the resistance of metal roof panel systems to water penetration when water is allowed to hit the outside face of the panel and an air pressure difference is applied such that the water would be drawn through the specimen should any breaches exist. 5.2 Results A water spray rack was mounted to the top of the chamber system in a fashion that allowed for total coverage of the specimen s outdoor face. Air was exhausted from the chamber at a rate enabling pressure differences of 2.8 psf and 6.24 psf. Once these differentials were obtained, water was sprayed at the specified rate onto the roof panels. An overflow system was utilized such that a ponding level of.5 was maintained during the entire test. After 15 minutes, both air and water were removed from the specimen to enable the evaluation of water penetration. The entire underside of the specimen was checked and it was verified that no leakage had occured. The table below provides information regarding the surface and water temperature during the implementation of the water test.

The figure below is indicative of these locations. Figure 5 - Potentiometer locations ASTM E specifies that the product experiences a pattern of loading in which it is exposed to the test pressure for not less than 60 seconds until increasing deflection is no longer apparent. The product is then allowed to relax for a time period not more than 5 minutes. This is repeated for a minimum of 6 times to create a deflection vs. load curve.

40 Q.E.D. Inc. / QEDLAB: AAMA Accredited Laboratory & Field Testing Agency Project ID: # 2086 Ref: Taylor Metal DATE: Q.E.D. has the capability to garner a continuous input of deflection readings throughout the entirety of the structural test. This enables not only the establishment of a deflection vs. load curve but also a deflection-over-time curve. The second curve is useful in the sense that it gives information regarding the products performance under stress as time progresses. The product was tested at the following pressures in accordance to ASTM E ; 25 psf, 35 psf, 45 psf, 55 psf, 65 psf. One of the seam clips disengaged as pressure was increased to 65 psf. This created a large pathway for airflow, inhibiting the maintenance of air pressure. The photographs below indicate this result.
