Iso Board For Flat Roofs

The various materials used for face sheets include aluminum foil perlite board wood fiberglass board osb and fiberglass mats.

Iso board for flat roofs.

Iso is available in a range of thicknesses that come in increments of 1 inch. Energyguard polyiso roof insulation an insulation board made of glass fiber reinforced cellulosic felt facers bonded to a core of isocyanurate foam. It accounts for over 60 of all installs. Technically iso is liquid foam sprayed against face sheets which then expands to form a board.

Flintboard iso is specifically recommended for hot asphalt or coal tar bur modified bitumen metal and single ply membrane systems. Consists of recycled newsprint to provide strength to the board as well as high recycled content. The thinnest board is 1 inch. Iso is often referred to as composite board insulation when the face sheets consists of a rigid board material.

For a 1 inch board equivalent of 6 r value.

We recommend having at least 20 r value worth of material for optimal energy efficiency. Insulated ceilings retard heat flow into the living areas in summer and contain generated heat in winter providing a comfortable living environment. The most efficient and best insulation used is rigid foam polyiso. It provides a soft protective base for the rubber.
