Insulation for use with all types of Roofing Membranes
Rmax Multi-Max FA is a rigid, foam plastic, thermal insulation board composed of polyisocyanurate foam bonded to glass fiber/organic mat facers on each side. This roofing insulation is suitable for use in insulated roofing system constructions utilizing built-up roof, modified bitumen or single-ply membranes and metal panel roofing systems. Multi-Max FA is approved for use in new roofing constructions and limited retrofit/recover roofing constructions over steel, wood, non-combustible and certain types of nailable roof decks.
Multi-Max FA is available in standard four (4) foot wide panels. Standard panel lengths are four (4) and eight (8) feet. Contact Rmax Sales for availability. See "Thermal Properties" for standard thicknesses and thermal resistance values of Multi-Max FA.
Multi-Max FA is shipped in bundles that are approximately 48 inches high and wrapped in plastic for easy handling.
Multi-Max FA is applied to the roof deck in order to provide a layer of thermal insulation and a suitable substrate for the application of the many different kinds of roofing membranes available in the market today.Multi-Max FA must be secured to steel or wood decks with FM listed mechanical screw and plate fasteners. Multi-Max FA may be secured to other types of "nailable" decks with suitable mechanical fasteners for that type of “nailable” deck. Multi-Max FA may be secured to a concrete deck with suitable mechanical screw and plate fasteners as an alternate method of attachment. Refer to “General Notes for Use and Installation of Rmax Roofing Insulations.” Multi-Max FA may be adhered to properly prepared concrete roof decks with hot bitumens or air-cured polyurethane foam adhesives. |
