Fibre-free EcoTherm Eco-Versal PIR Insulation is a rigid polyisocyanurate (PIR) insulation core with aluminium foil composite facings on both sides. EcoTherm Eco-Versal can be used in both new build and upgrading the thermal performance of existing building elements, providing a cost-effective means of reducing CO2 emissions and for compliance with Building Regulations/Standards.
Ideal for use in, floors, pitched roofs, cold flat roofs, timber frame walls, solid walls, dormer check, ceilings and room in the roof applications.
THERMAL PERFORMANCE
The thermal conductivity (λ-value) of Eco-Versal is 0.022W/mK, thermal resistances are shown in table 1. The low emissivity surface of the reflective foil facing can cut radiant heat transfer across an adjoining air-space.
DURABILITY
When correctly installed, Eco-Versal has an indefinite life and its durability depends on the background/supporting structure and conditions of its use. It should not be used to isolate dampness nor be used in continuously damp/humid conditions.
FIRE PERFORMANCE
EcoTherm Eco-Versal achieves BS476-7: 1997 Class 1 rating. The specific fire resistance of the system will depend upon the conditions of use.
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.
ENVIRONMENTAL
EcoTherm PIR insulation is manufactured with a blowing agent that is CFC/HCFC free and has zero Ozone Depletion Potential (ODP) with a low Global Warming Potential (GWP). Eco-Versal corresponds to the BRE Global Green Guide generic specification which achieves a summary rating of A. EcoTherm Eco-Versal is approved as an Energy Savings Trust (EST) Listed product. Eco-Versal is not classified as a dangerous substance, so no special provisions are required regarding carriage. The fibre-free insulation core and facings resist attack by mould and microbial growth and do not provide any food value to vermin.
