b'Caulk/Sealant, Insulation,Water and Air Barriers 16 1716. CAULK SEALANT-Sealants meeting industrystandards AAMA 800 or ASTM C920 enable provisionof a water and air-tight barrier between two surfaces.Be sure the adhesion properties match the two surfaces to be sealed.17.SPRAY PU FOAM - Low pressure, flexible foammeeting AAMA 812 specification and ASTM D 2842for water absorption is injected between the roughopening and the new window or door to establish athermal, air and water barrier around the perimeterof the newly installed product. 18 1918. WEATHER RESISTIVE AIR BARRIER,BUILDERS TAPE & PLASTIC VAPOR BARRIER -Weather Resistive Barriers, Air Barriers and WaterResistant Barriers are used on exterior walls. VaporBarriers and Builders Tape are used on warm sideinterior walls. They need to integrate with new windows and doors to work in concert with them.19. FOAM INSULATION BOARD -Sometimes calledstyro-foam (brand) or foam core (another brand),these rigid boards and others like them are used as a sheathing product underneath stucco or otherapplied exterior finishes. They provide air and20 21moisture and water resistance and a good substratefor the applied finish.20. BATTE INSULATION - While not recommendedfor most installations, can be used to insulatebetween the new window or door product and therough opening. Water and/or compressing the fiber-glass material can diminish the insulation value.21. COMPRESSED FOAM SEALANT TAPE - AEuropean developed product, this sealant tape slowlyexpands and fits the contours of both surfaces of therough opening and the door or window frame andmakes a complete seal with minimal pressure. 22 2322. LIQUID FLASHING - Liquid applied flashing isideal for new construction Cement Masonry Unitsand when old frames remain in place. Liquid flashingcan be applied around wood bucks and to create aseffective sill drainage pan alternative.23. BACKER ROD - It is unwise to fill a gap greaterthan 1/8 inch with caulk without using backer rod.In this way, the sealant sticks to the two surfacesand the backer rod acts as a buffer to allow expansion, contraction and movement without breaking the bond.Note:This list of tools and hardware and application materials is typical but may not reflect the exact tools and hardwareprovided by the manufacturer or needed to install all of the window products. The list is for guidance and to be sure thatwhen the products are ready to be installed, all necessary materials are on hand or readily available.Window Fitters Guide to Window Installation42020 AWDI, LLC Do not reproduce without permission'
