Who we are

Where does the heat go?

• 45% of heat lost through uninsulated solid walls

• 33% of heat lost through uninsulated cavity walls

• 25% of heat lost through the roof/loft space

• 20% of heat lost windows and doors

The Benefits of Insulation

• Solid Wall Insulation

• Save around £375 a year on heating bills• Reduce (CO 2) emissions by around 2 tonnes each year

• Cavity Wall Insulation

• Save around £110 a year on heating bills• Pay back in just 2 years• Reduce (CO 2) emissions by around 560kg each year

• Loft insulation

• Save around £145 a year on heating bills• Pay back in under 2 years• Reduce (CO 2) emissions by around 800kg each year

The Opportunity

Over half the existing housing stock in the UK has inadequate levels of insulation!

• 7m properties have solid walls that are not insulated

• 8m properties with uninsulated cavity walls

• Around 13m lofts with inadequate insulation

• Most people have some loft insulation but it is not sufficient – to comply with modern standards it should be 270mm deep

+ 4.5m micro/SME businesses

• Carbon Emissions Reduction Target - 2012

• Community Energy Saving Programme - 2012

• Energy Company Obligation - 2013

• Green Deal – October 2012

• Residential and commercial buildings

Market Drivers

Cavity Wall Insulation

• Permanent, maintenance free home improvement, lasting the life of the building

• Most homes built from 1920 onwards have cavity walls

• Cavity wall insulation fills the cavity between the inner and outer walls - reducing the amount of heat that is lost

Cavity Wall Insulation

• Small holes are drilled into the outside walls and CWI material is blown into the cavity

• Holes in the brickwork are filled post insulation

• 3 types of material are used

• mineral wool/polystyrene beads/foam

• CIGA (Cavity Insulation Guarantee Agency) issue an independent 25 year guarantee covering defects in materials and workmanship

Loft Insulation

• Loft insulation reduces the amount of heat escaping through the roof by providing a layer of material with air pockets that trap the heat

• The recommended depth of loft insulation is 270mm (mineral wool)

• There are three types of insulation used:

• mineral wool quilt/blown mineral wool/cellulose and polystyrene boards

Loft Insulation

• Mineral wool quilt is the most common material used

• Quilts are laid down between the joists then another layer of insulation is `cross-laid' to cover the joists

• Insulation makes the house warmer but the roof colder so it is important to insulate tanks and pipes in the loft space

Internal Wall Insulation

• Suitable for installation where the external wall appearance cannot be changed (planning restrictions)

• Can be utilised where there is insufficient external clearance to install external wall insulation

• It can be installed on a room-by-room, single façade or whole house basis, as part of a full refurbishment plan

External Wall Insulation

Adhesive

Decorative Render Finish

Insulation

Insulation Fixing

Render with Reinforcing Mesh

• Very high levels of insulation possible.

• No internal disruption.

• Effective for new and existing buildings.

• Building fabric is protected from the weather (extends buildings life).

• Overcomes cold bridging, condensation and dampness.

• Enables building appearance to be improved / modified.

External Wall Insulation

Hybrid Approach

• Front appearance retained using IWI

• Side/Rear and any extension can benefit from EWI

• The same techniques are adopted for standard IWI/EWI
