What is cavity wall insulation?

Cavity wall insulation involves placing insulating material in the gap between the inner and outer bricks of your property. This makes it more energy-efficient by preventing heat escaping.

Over a third of all the heat lost in an uninsulated home escapes through the walls. Cavity wall insulation lowers your energy costs and helps reduce harmful emissions being released into the environment.

Which materials are used to insulate walls?

Expandable polystyrene (EPS) is a lightweight cellular material consisting of fine spherical shaped particles which are comprised of 98% air and 2% polystyrene. It is a rigid cellular plastic containing an expansion agent called pentane.
EPS Bead has low thermal conductivity and low moisture absorption. It is lightweight, safe and easy to use.

What are the benefits?

Insulating your walls can reduce your energy bills by up to 1/3 whilst increased energy-efficiency helps lower your impact on the environment.

How do Insulation grants work?

Under the Government led ECO grant scheme the major energy companies have been asked to set aside funding for grants.

Grant funding is used to install energy saving measures for homeowners and private tenants where someone in the household claims any of the following benefits or tax credits –

• Armed forces independence payment
• Attendance allowance
• Carer’s allowance
• Disability living allowance
• Income support
• Income-based JSA
• Income-related ESA
• Industrial injuries disablement allowance
• Industrial injuries disablement benefit
• Pension Credit Guarantee Credit Element
• Personal independence allowance
• Personal independence payment
• Severe disablement allowance
• Universal Credit
• War pensions mobility supplement
• Working tax credit
• Child Tax Credit
• Child benefit (dependant on income & dependants)

If your home was built after the 1920’s there is a good chance it has cavity walls. It shoul;d be noted that timber framed properties and solid walls are not suitable for cavity wall insulation.

About the ECO insulation grant scheme

Government wall insulation grants are designed to prevent your home losing heat.

In England it is estimated that over 30% of emissions come from domestic properties

The government has committed to reducing carbon emissions by 100% by 2050 compared swith 1990 levels (Climate Change Act 2008). This is part of an international effort to cut emisions and to improve the environment on a worldwide level
