Foil Faced Rigid Insulation Fire Rating

Rigid foam insulation packs a lot of r value into a thin package but not all rigid foam performs the same.

Foil faced rigid insulation fire rating.

It is constructed from closed cell polyisocyanurate foam core bonded on each side to aluminum foil facers during the manufacturing process. Rigid foam insulation whether it is expanded or extruded polystyrene does have to be covered if it is installed in the interior of a building. Thermax sheathing specially designed to hold a class a fire rating. Thermax sheathing can be installed exposed to the.

Tuff r polyisocyanurate insulation consists of high performance high r value closed cell polyisocyanurate foam core boards sandwiched between a choice of durable exterior foil facers. On tuff r insulation one facer is a continuous sheet of aluminum foil. Roxul safe is ul and intertek approved as a forming material for numerous firestop systems. Choose rigid insulation wisely and consider the effect its characteristics will have on the performance of the your project overall product cost and the best way to get the bang for your buck.

Depending on whether or not the foil backing on the existing foil backed gypsum board is perforated or not the perm rating of that surface could be near zero that is very resistant to moisture movement forming a moisture barrier in the wrong place. Thermax sheathing is a nonstructural rigid board insulation with a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum faces. Roxul safe is a lightweight semi rigid stone wool insulation that provides superior fire resistance and sound control. The other is a tri plex facer consisting of a three ply laminate of durable kraft.

The glass fiber reinforcement provides improved fire performance and dimensional stability. This standard is used solely to measure and describe properties of products in response to heat and flame under controlled laboratory conditions and should not be used to describe or approve the fire hazard of materials under actual fire conditions. This wall covering must have a minimum fire rating to protect the insulation from quick combustion during a fire. Iko enerfoil sheathing wall insulation is a rigid polyisocyanurate foam insulation board with high thermal properties.
