Thermal Insulation Board For Roof

Achieving greater r values in exterior walls.

Thermal insulation board for roof.

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. 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. In exterior walls add insulating sheathing to achieve a greater r value in your wall system. 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.

The higher the r value the better the thermal performance of the insulation. It s light weight provides ease of handling. 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. With excellent thermal conductivity coefficient they make an unrivalled solution allowing you to reduce the insulation thickness by half.

A cover board is a relatively thin substrate that s placed over the primary thermal insulation in a roofing system. An exceptional fire barrier thermal barrier and re cover board used in various commercial roofing systems. This is a very universal and efficient solution for all kinds of exposed roofs. Thermal insulation is becoming an increasingly important part of construction performance.

Densdeck roof board. 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. Rigid roof insulation 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.

It is best to use thermal insulation materials in the form of boards with profiled edges which allow joining boards with overlap. Spray polyurethane foam has created an alternative for thermal insulation boards. We supply flat roof insulation boards that are compatible for both adhered and mechanically fixed single ply roofs and also felt roof systems. 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.

You can achieve better thermal performance in your attic by adding an additional layer of insulation.
