Loft and Roof Insulation
Most of the heat lost in a property is lost through the roof. Loft insulation can help to retain heat in your home and reduce your energy bills by as much as 25%, saving you money in the long term as roof insulation can last for up to 40 years.
We are often asked how much loft insulation costs. Roof insulation can typically be funded by the energy-saving scheme and the price of loft insulation will often depend on the type of loft insulation used. Attic insulation can consist of glass, rock wool, blown cellulose, or quilted mineral wool.
Our experienced and friendly loft insulation installers will come to your property and assess the amount of room between the joists on the loft floor. They will then advice on which type of roof insulation material should be used and how best to create the most space in your attic so that you have adequate room for storage.

What is Loft Insulation?
Loft insulation stops the heat from your house from 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 from 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.
How Does It Work?
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 the 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 useful storage space for other household goods. This is a service Heat Insulation can offer.
It is possible to insulate your loft yourself, providing it does not have any damp problem, is not a flat roof and is easy to access. However, we don’t recommend you do this as electric cables and ventilation must be treated in a specific way to avoid damage to your property.
We use the highest standard of insulation to ensure maximum efficiency. This cannot be bought from your local DIY store meaning doing it yourself may not always prove the best results.
Usually, completion of the insulation can be done within a few hours, and the benefits can be felt almost instantly.
