3 November 2016 ROOF SIPs Installation Manual 1. General Requirements 1.1 Scope The basic design and construction requirements for the Thermapan Structural Insulated Panel (SIP) roof system is set forth in this specification. Criteria for materials, environmental control, design loads, and structural design are included. Where requirements are based on internationally recognized standards and specifications, these standards and specifications are referenced without elaboration. Installers shall reference engineering design package for fastening arrangements. 2. Materials 2.1 The Thermapan Roof SIP is composed of an expanded polystyrene (EPS) foam core laminated between two layers of oriented strand board (OSB) with a structural adhesive. 2.2 Framing Lumber shall be DOC PS 20 or NLGA No.2 or better. 2.3 Wire nails, ring nails, spikes and staples shall conform to CSA B111 or ANSI/ASME B Wood screws shall conform to ANSI/ASME B SIP screws shall conform to ICC-AC Caulking Compounds shall conform to CAN/CGSB or ASTM C Polyethylene Sheeting shall conform to CAN/CGSB-37.2, CAN/ CGSB-37.16, or ASTM D Low expansion foam seal shall conform to AAMA Structural adhesive shall conform to CAN/CGSB 71GP26, APA AFG-01 or ASTM D Electrical Wiring 3.1 An optional furring for electrical passage should be fastened to the underside of the roof SIP between the vapour barrier and the interior finish. See details R-1, R-4 and R-5. Roof SIP - Installation Manual 3

4 November Interior Finish 4.1 The interior of the roof SIP can be finished with any of the common required building code materials. It is recommended that the SIP joints and connections be sealed as per Details AB-1, AB-2 and VB Exterior Roofing 5.1 Consult your local building code and refer to details R-11 and R-12 for roofing applied to SIPs.

5 November 2016 MATERIALS ESTIMATING Roof (Vaulted Ceiling) Estimation Only Lumber Requirements: Perimeter of roof or fascia length Caulking and Sealant Requirements: Every 1200 sqft (111 m 2 ) of SIP equals 1 case of Expandable Foam Every 2000 sqft (185 m 2 ) of SIP requires 1 case of Sealant Fasteners: Recommend 2 (50mm) Ring nail or 2 (50mm) screws for connection to panel ~ 1.25 times the square footage of SIPs... nailing of spline SIP screws use 40% of Roof square footage Roof SIP - Installation Manual 5

6 AIR BARRIER RECOMMENDED DETAILS FOR AIR BARRIER SEALANTS All sealants, FOAM (A) or CAULKING (B), should be applied onto the SIP in a continuous rectangular pattern along the outer most edge of the area to be sealed. (A) A low expansion FOAM SEALANT should conform to the AAMA standard. Apply a 1/2 inch or a 12.5 mm diameter of a continuous bead of expandable foam sealant onto the SIP: Expandable Foam Sealant Bead EPS (B) A CAULKING SEALANT should conform to ASTM C and/or CAN/CGSB M. Apply a 3/8 inch or a 10 mm diameter continuous bead of caulking onto the lumber spline: CAULKING (CONTINUOUS BEAD) Caulking Bead LUMBER STUD OR SPLINE AIR BARRIER DETAILS FOR AIR BARRIER SEALANTS REVISION DWG.

8 VAPOUR BARRIER RECOMMENDED DETAILS FOR VAPOUR SEALING SIP CONNECTIONS The function of a vapour barrier is to control the entry of water vapour into the building assembly. Vapour barriers should not be confused with an air barrier. All SIP seams and connections must be VAPOUR SEALED from the INTERIOR. These are recommended vapour barrier methods: OSB EXTERIOR INTERIOR CONTINUOUS 6 MIL POLY OVER ENTIRE SIP ASSEMBLY SEE AIR BARRIER DETAIL (AB-2) 6 MIL POLY STRIP CAULKED TO OSB SEE AIR BARRIER DETAIL (AB-2) CONTINUOUS 6 MIL POLY RECOMMENDED 6 MIL POLY STRIPS & CAULKING EXTERIOR INTERIOR CAULKING SEE AIR BARRIER DETAIL (AB-2) OSB SEE AIR BARRIER DETAIL (AB-2) SIP TAPE CAULKING SIP TAPE VAPOUR BARRIER DETAILS FOR VAPOUR SEALING SIP CONNECTIONS NOVEMBER 2010 REVISION DWG.
