Heat rises, so a quarter of your heat is wasted through the roof. Insulating your loft is an effective way of reducing your heating bills.
Having effective roof insulation installed can reduce the heat lost from your home by 20% or more. You may already have loft insulation in place, but if this is not thick enough (or is incorrectly fitted) it may be allowing heat to escape – and the colder it is outside, the faster heat will escape from your home.
Loft insulation is effective for at least 40 years so the savings made on your energy bills will pay for the cost of having it installed over and over again in time.
Even if your loft is already insulated it is worth getting a survey carried out to check that there is enough insulation to enable you to get maximum savings. The depth of insulation that is required is 270 to 300mm. If you have less than that is possible to have insulated topped up. Providing that your loft is easy to access and has no damp or condensation problems it should be easy to insulate.
If the loft has easy access and the joists are regular then it can be insulated with rolls of mineral wool.
If you want to use your lost as storage you will probably want to lay boards . With the current depth of insulation required you will not be able to do this without carrying out the following:
Raising the Level the joists to allow for the insulation.
If your lost is hard to access, you can have blown insulation installed. This involves using a specialist machine to blow the insulation material in to the loft. This material is fire retardant material which is made of recycled newspaper.
