Loft Insulation
Around 25% of heat is lost through the roof.
Loft insulation is a barrier of material installed between the joists or in the rafters, and is a great way to improve heat retention and save on energy bills. Insulating an uninsulated loft with 270mm of loft insulation can help you save over £500 on energy bills per year.
Room-in-Roof (RIR) Insulation
Like loft insulation, Room In Roof insulation (RIR) will act as a barrier to keep the heat down in your home where it belongs.
If you use your loft or attic space as a living area, we can secure RIR insulation funding. We can make sure that all areas are fully insulated, maximising the energy efficiency of the space utilised.
Cavity Wall Insulation
Around 35% of heat is lost through uninsulated walls.
Cavity wall insulation fills the gap between your external and internal walls, providing a barrier between the cold outside and your warm home. Adding this type of insulation is essential in saving energy, and the correct cavity wall insulation can help you save over £600 per year on your energy bills.
Solid Wall Insulation
If your home was built before the 1920s, its external walls are likely solid rather than cavity walls. Solid wall homes are especially vulnerable to heat loss due to their design and construction materials. They can be insulated from either the outside or inside, which can cut heating costs considerably.
