Thermal Insulation Board For Roof

Rigid roof insulation board.

Thermal insulation board for roof.

It is one of the most suitable insulation types for adhered roof systems and can also be used in ballasted roof applications. Composed of a closed cell polyisocyanurate foam core bonded in the foaming process to 1 2 thick duraboard an expanded perlite mineral aggregate board on one side and a fiber glass reinforced facer on the other. In exterior walls add insulating sheathing to achieve a greater r value in your wall system. Achieving greater r values in exterior walls.

It s made of environmentally sound closed cell polyisocyanurate foam bonded to a durable white matte non glare aluminum facer and a reflective reinforced aluminum facer. Spray polyurethane foam has created an alternative for thermal insulation boards. The higher the r value the better the thermal performance of the insulation. This is a very universal and efficient solution for all kinds of exposed roofs.

It is best to use thermal insulation materials in the form of boards with profiled edges which allow joining boards with overlap. Not only do we withstand hail damage but our roof boards maintain their bond to the roof membrane lowering the likelihood of a catastrophic roof failure. The national roofing contractors association nrca endorses the use of cover boards in nearly all low slope roof assemblies to relieve some of the negative attributes the insulation has such as moisture absorption face. We supply flat roof insulation boards that are compatible for both adhered and mechanically fixed single ply roofs and also felt roof systems.

A cover board is a relatively thin substrate that s placed over the primary thermal insulation in a roofing system. It s light weight provides ease of handling. Densdeck roof board. R matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation r matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation board.

Exceptional dimensional stability and rated for extreme hail rockwool stone wool insulation roof boards have meet both the fm severe hail and the ul 2218a standard for impact resistance. An exceptional fire barrier thermal barrier and re cover board used in various commercial roofing systems. With a warm roof the usual process is to split the insulation into two layers. If 180mm is to be installed then 100mm board might be introduced between the rafters there has to be a minimum 25mm air gap between the insulation and the underside of the tiles or slates with an 80mm board running across the rafters.

Thermal insulation is becoming an increasingly important part of construction performance.
