Cavity Wall Insulation
Cavity Wall Insulation
Cavity Wall Insulation stores the heat within the inner walls, bouncing it back into the room and holding it for longer. This gives you a more even temperature and gets rid of the draughts that come down from the walls.
How does this work?
The cavity is located between the inner and outer brickwork of the property
The main materials used by NIA installers are Mineral Wool (Glass or Rock Wool), EPS Bead (Polystyrene bead) and PU Foam (Polyurethane Foam)
Cavity Wall Insulation can lower your heating bills, lower wear and tear on your boiler and reduce global warming and climate change
CIGA (Cavity Insulation Guarantee Agency) issue an independent 25-year guarantee covering defects in materials and workmanship.
There is also a 25-year insurance backed guarantee available for PU Foam.
The recommended cavity width is 50mm
Cavity Wall Insulation can give you an annual saving of up to £275. There are a number of grants and schemes available to homeowners which can substantially reduce the cost of installing this product.
Your Eligiblity for this Grant?
If your property was built after 1995 then it might have been partially insulated and you are probably eligible for a cavity top-up.
You need to receive an ECO3 benefit and have an empty or partially filled brick cavity wall.
The property should be located in England, Scotland or Wales and be heated by a gas, oil, LPG, electric boiler or electric storage heaters (ESH).
You must be the Homeowner, Landlord or a Private Tenant. Private Tenants must have their Landlord permission. Landlords must have an eligible ECO3 Tenant living in the property that requires insulation.
Also, Housing Associations can claim insulation grants if their properties are heated by any type of electric heaters and they have eligible ECO3 Tenants.
Your property is less than 3 storeys high.
If your property has already had cavity wall insulation over 15 years ago and is heated by electric then we can extract this old material and fill it again with the latest energy saving insulation.
Note: You must have 67% or more of the cavity walls available to be insulated. Unfortunately, we cannot just insulate a new extension of the property under this funding.
You may also be eligible for a FREE A-rated replacement boiler if you are the homeowner living in your property and have an older gas, oil or LPG boiler.
