Foil Faced Rigid Insulation Fire Rating

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.

Foil faced rigid insulation fire rating. The other is a tri plex facer consisting of a three ply laminate of durable kraft. Iko enerfoil sheathing wall insulation is a rigid polyisocyanurate foam insulation board with high thermal properties. 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. It is constructed from closed cell polyisocyanurate foam core bonded on each side to aluminum foil facers during the manufacturing process.

Rigid polyurethane and polyisocyanurate foams are effective insulation materials that can be used by architects builders and contractors to meet today s stringent energy code requirements 1 depending on product specific composition factors the fire performance characteristics of polyurethane. We suggest foil faced foam insulating board with the joints sealed with foil tape. Roxul safe is a lightweight semi rigid stone wool insulation that provides superior fire resistance and sound control. This wall covering must have a minimum fire rating to protect the insulation from quick combustion during a fire.

Thermax sheathing can be installed exposed to the. Roxul safe is ul and intertek approved as a forming material for numerous firestop systems. 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. The glass fiber reinforcement provides improved fire performance and dimensional stability.

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. 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. Thermax sheathing specially designed to hold a class a fire rating. 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.
