Heat rises, and in an uninsulated home, a quarter of your heat is lost through the roof. Insulating your loft, attic, or flat roof is a simple and effective way to save that waste and reduce your heating bills – you can even do it yourself.
Loft insulation is effective for at least 40 years and it will pay for itself over and over again in that time.
If your loft is easy to access and has no damp or condensation problems, it should be easy to insulate.
If access is easy and your joists are regular, we use rolls of mineral or glass wool insulation. The first layer is laid between the joists – the horizontal beams that make up the ‘floor’ of the loft – then another layer is cross-laid at right angles to cover the joists and make the insulation up to the required depth which is currently 270mm or 11 inches!!
Insulation stops heat escaping from living spaces, so it will make your loft space cooler – which could make existing damp or condensation problems worse. Get professional advice before installing insulation, to see if you can fix the damp problems first.
Insulating between the joists of your loft will keep your house warmer but make the roof space above colder. Pipes and water tanks will be more likely to freeze, so you will need to insulate them. Heat Insulation provide this within the funding obtained for you.
The cooler air in your insulated loft could mean that cold draughts come through the loft hatch. To prevent this, we install UPVC strips of draught-excluding material around the edges of the frame.
