What is purpose of protection board?
The cover board is adhered using hot asphalt or a specially formulated adhesive that is applied over the top surface of the bottom layer of insulation. Second, the cover board serves to insulate the fastener eliminating energy loss and possible thermal bridging at fasteners and insulation joints.
What do you cover insulation board with?
Once the foam board is in place it can be covered with waterproof concrete board or specially treated sheet rock. These coverings will ensure a good long life for the foam insulation by keeping moisture from its surface.
What is Protection Board?
CCW Protection Board H is a heavy-duty asphalt-impregnated organic mat with a fine mineral applied to the surface to prevent sticking in the roll. CCW Protection Board-H is very tough and provides positive protection to the waterproofing membrane during installation of other work.
Can polyiso be used below grade?
What many builders don’t realize is that, depending on facer type used, polyiso can also be used in below-grade applications in both commercial and residential buildings to protect basement and foundation walls.
What is perlite board?
EnergyGuard™ Perlite Recover Board is a heavier duty 1/2″ (13 mm) thick perlite roof insulation board composed of expanded perlite, cellulose binders, and waterproofing agents.
Can you use fiberboard for roofing?
Fiberboard rigid insulation is a product historically used in roof recover jobs, or jobs where a new roof is being installed over an existing roof. It has an R-value of 4.0 per inch, and is typically installed in thicknesses of ½” to provide a substrate between the old roof and the new roof.
Do I have to cover rigid foam insulation?
A: Yes, but to comply with building codes, all foam plastics must be covered with a 15 minute thermal barrier. Gypsum board, ½” thick is a common covering.
What is protection board made of?
Protectoboard is a versatile asphaltic cover board composed of a mineral-fortified asphalt core between two layers of high-strength reinforcing fiberglass mat.
What is the highest R value for rigid insulation?
Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation. This type of rigid foam usually comes with a reflective foil facing on both sides, so it can also serve as a radiant barrier.
Is rigid insulation waterproof?
Waterproof rigid insulation is used on roofs. Polyiso is a rigid foam board insulation used for roofing and for insulating walls and ceilings. It is a composite insulation made from various chemicals and synthetic materials, which are heated and then cooled to form rigid panels.
What is rigid thermal insulation?
Rigid insulation is a building material used to provide thermal resistance to walls, foundations, and roofs. It is available in formed or extruded sheets of varying sizes, which are made from polystyrene or polyurethane . This material helps to improve the energy efficiency of a home by keeping cold or hot air from penetrating the walls.
What is rigid foam?
Rigid Foam Insulation: Rigid foam insulation consists of solid boards that have a radiant barrier on at least one side. This material is ideal for the attic ceiling, basement walls, and crawl space walls. Rigid foam is extremely durable, making it a great choice for unfinished spaces in the home.
What are insulation panels?
Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board ( OSB ).
