EcoTherm Eco-Versal

Ecotherm’s Eco-versal insulation board, The 5 in 1 solution 

As part of the EcoTherm insulation range, Eco-Versal comprises a fibre-free rigid polyisocyanurate (PIR) insulation core face with an aluminium foil composite on either side. Eco-versal can be used in both new build and existing building applications allowing the thermal performance to be upgraded as well as providing a cost-effective way of lowering CO2 emissions all while complying with Building Regulations and standards. The Eco Versal insulation board comes in a vast range of thicknesses allowing it to be flexible to your specification (25mm-150mm) which makes it the ideal insulation solution for pitched roofs, floors, walls, dormer cheeks & ceiling.

Description

Eco-Versal comprises a fibre free rigid polyisocyanurate (PIR) insulation core with aluminium foil composite facings on both sides.

Applications

Applications include 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. 

■  Floors
■ Pitched roofs
■ Cold flat roofs
■ Timber frame walls
■ Solid walls
■ Dormer cheek
■ Ceilings
■ Room-in-the-roof applications

EcoTherm Eco-Versal achieves typical U-values as shown in tables 2, 3 and 4.

In a floor application the U-value will be dependant on the P / A ratio (exposed Perimeter / Area).

WATER VAPOUR RESISTANCE

Eco-Versal has an integral vapour control layer to minimise the risk of interstitial condensation.

The foil facings have a high water vapour resistance and will, therefore, provide a significant resistance to water vapour transmission.

If required, apply proprietary self adhesive foil tape at board joints to complete the vapour control layer and to maximise thermal performance.

The requirement for a vapour control layer should be assessed to BS5250: 2002 (Code of Practice for control of condensation in buildings).

COMPRESSIVE STRENGTH

The typical compressive strength of Eco-Versal is 140 kPa when tested at 10% compression to BS EN 826: 1996 Thermal Insulating Products for Building Applications – Determination of Compression Behaviour.

SPANNING

When fixed to timber framing, metal channels, rafters or battens, the maximum board span should be 600mm.

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. For advice on the correct specification please contact EcoTherm Technical Services.

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).
