Foil-faced, Polyisocyanurate (PIR) rigid board insulation is created via a continuous foaming process that creates a tight cell structure and an inseparable bond between the foil and board. The yellow foam insulation comes in standard sizes 2400 x 1200 and thicknesses range from 25mm to 150mm.
The Polyisocyanurate (PIR) foam core has an extremely low thermal conductivity, making the required thickness of insulation less than for most other types of insulation and making it an ideal choice where you are restricted with depth. The foil laminate facings also contribute to improved thermal performance and the low emissivity surface of the reflective foil can cut radiation heat transfer across an adjoining space.
The board is a strong, rigid board suitable for self-supporting applications in floors, walls and roofs.
In the event of a fire, the board will remain stable at temperatures up to 400 degrees centigrade and has achieved class 1 surface spread of flame. If temperatures reach higher than 400 degrees, a protective char forms on the surface on the boards to slow the spread of flames, the board may be used behind non-flammable materials such as plasterboard.
The insulation boards have a low thermal conductivity, which means less of the product is needed to achieve the desired thermal resistance and the tight-cell, rigid construction is designed for longevity.
Biological and Moisture Resistance
Created to be mould, pest and insect free, the boards will never rot, they have a low moisture absorption capacity and high vapour resistance.
The strong rigid construction gives the board the ability to withstand the weight of load bearing floors, when the product is installed according to the manufacturers specifications and industry codes of practice, the insulation boards have a service life comparable to that of the rest of the building.
