Understanding 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.

Solid Wall Insulation

If you live in a home with solid walls, 45% of your heat is escaping through the walls which is costing you money.

Loft Insulation

As much as a third of the heat you pay for could be escaping through your roof. It’s an easy way to save money.

Draught Proofing

Draught proofing is one of the most inexpensive and effective energy efficiency measures for the home.

Spray Foam Insulation

Polyurethane (PU) Foam helps to reduce heat loss so reducing your energy bills.
