2400MM X 1200MM X 37.5MM PIR BACKED PLASTERBOARD
£58.80
The typical compressive strength of the insulation is 140 kPa when tested at 10% compression to BS EN 826:2013 Thermal Insulating Products for Building Applications – Determination of Compression Behaviour.DURABILITY
The product is stable, rot proof and durable and when correctly installed has an indefinite life. Durability depends on the method of application, the supporting structure and conditions of use. It should not be used to isolate dampness nor be used in continuously damp/humid conditions. The fibre free insulation core and facings resist attack from mould and microbial growth and do not provide any food value for vermin.RESISTANCE TO SOLVENTS
PIR insulation resists attack from alkalis, dilute acids, mineral oil and petrol. The fibre free insulation core is not resistant to ketonic solvents. Damaged boards should not be used.
THERMAL CONDUCTIVITY
The thermal conductivity (lambda/λ – value) of the insulation is 0.022W/mK.
The 12.5mm gypsum plasterboard element has a thermal conductivity (lambda/λ – value) of 0.19W/mK.
WATER VAPOUR RESISTANCE
Eco-Liner has an integral vapour control layer to minimise the risk of interstitial condensation. If increased water vapour resistance is required, apply 2 coats of a proprietary sealer in drylined/taped/jointed systems.
The insulation facing has a high water vapour resistance and will, therefore, provide a significant resistance to water vapour transmission.
