Loft and Roof Insulation

Loft insulation is located between the joists on the loft floor of your property, usually consisting of Glass or Rock Wool, Blown Cellulose or Quilted Mineral Wool it can reduce your energy bills by as much as 25%.

It can last for up to 40 years, can be funded by energy saving schemes and with the right installation ensure that your loft and roof space is still usable for storage.

What is Loft Insulation?

Loft insulation stops the heat from your house escaping through your roof. With heat naturally rising a poorly insulated roof or loft space can be increasing your bills by as much as 25%.

Layers of mineral or glass wool are laid between the joints. 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!!

If your loft is easy to access and has no damp or condensation problems, it should be easy to insulate.

Are there any Risks?

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 provides 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.

Loft InsulationHow it works?

Loft and roof insulation work by re-directing the heat that would escape from your home through the roof back into your home. The insulation often made of Glass or Rock Wool, Blown Cellulose or Quilted Mineral Wool is laid between the joints to act as a barrier for the heat slowing down the transfer of heat between your living space and outside world.

Even with insulation laid between and across the joists, you can still have a usable space by laying boards across this. This can be done by any qualified joiner who will raise the joist levels with one of a variety of products, this will allow for a useful storage space for other household goods. This is service Heat Insulation can offer
