DECC forecast for solid wall insulation measures under Green Deal and new ECO

Industry Overview Opportunities • Green Deal – Insulation measures will play a key role

• ECO – Major focus on solid wall insulation will result in growth

• Kitchen/bathroom upgrades – Key opportunity to upgrade insulation of solid walls

• Funding available square metre basis – ThermoShell IWI can potentially attract funding for every square metre installed – Huge opportunity for sales

Industry Overview Internal Wall Insulation (IWI)

 No scaffolding required  Greater flexibility for installation  Generally less expensive than EWI

Industry Overview Internal Wall Insulation options – Aerogels – Insulated wallpaper – Rigid foam boards – Mineral wool installed in between timber studs – Mineral wool installed in between metal studs

Industry Overview What an IWI system needs to provide: – Thermal performance • U-value of 0.30 W/m2K for compliance with Part L1B 2010

– Acceptable thickness – Minimised risk of condensation – Minimal disruption during installation – Low environmental impact

Industry Overview What an IWI system needs to provide:





– Thermal performance



• U-value of 0.30 W/m2K for compliance with Part L1B 2010



– Acceptable thickness

– Minimised risk of condensation



– Minimal disruption during installation – Low environmental impact

EcoStud Extruded Polystyrene (XPS) + 15mm OSB 

No thermal bridging



Unaffected by moisture



Lightweight but with high compressive strength



Excellent pullout strength



Moisture resistant OSB

Earthwool EcoBatt Water repellent glass mineral wool • Manufactured with ECOSE® Technology • Compression fits between studs, allowing no air gaps preventing air movement and condensation • Glass mineral wool with a generic A+ Green Guide rating

ThermoShell Vapour Control Layer 

Vapour control membrane +  Standard plasterboard

Main benefits of the ThermoShell IWI system – Reduced thickness due to insulation properties of EcoStud – Can potentially attract funding for every square metre installed

– Cost effective – BBA certified system – LABC approved meaning no separate sign off or approval for each project – OFGEM recognised allowing funding allocation – High performance environmental credentials
