Would you like to reduce home heat loss?


The best way to do this is by installing loft insulation and roof insulation. Roof and loft insulation can help with condensation problems, which causes mold.

Loft rafters are often a part of the roof structure, so it's important that they are insulated as well! Keep reading for some tips on how to properly install these products in your home!

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft, attic, or flat roof is an effective way to reduce heat loss and reduce your heating bills.

Installed correctly, loft insulation should pay for itself many times over in its 40-year lifetime.

Loft insulation also helps with condensation, which causes mold. Loft rafters are often a part of the roof structure, so it's important that they're insulated as well!


Great resistance against heat loss makes foam one of the best insulators

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

Loose-fill loft insulation is the most popular type of loft insulation, it's usually made from wool or cellulose. It can be installed by a professional in about an hour and will need to be replenished every five years or so with more loose fill. which probably is not the best for a long-term investment.


Open-celled foam is breathable, when applied to any surface it allows any moisture present to dry out through evaporation, this is important as timber and masonry surfaces need to breathe to ensure that no damp or rot problems are caused.

Protective vapor-permeable membranes are normally used in conjunction with open-cell foam. These create a moisture barrier and provide protection for both the insulation itself, as well as preventing condensation from damaging timber or masonry surfaces below.

Ventilation is very important when insulating lofts because any enclosed space can get hot and humid.

What is Spray Foam Insulation?

Spray foam is an insulation product that comprises two compounds. These compounds are blown through hoses that meet at the spray gun combining the compounds into a single composite as they are sprayed onto the underside of the roof lining, felt, paper, boards, etc, between the rafters.

The spray foam insulation will reduce the cost of heating and cooling as well as provide a barrier against condensation from damaging timber or masonry surfaces below. Spray Foam Insulation can be installed in tight spaces such as lofts, where it is not possible to use other forms of insulation products. It does not require gaps for installation so perfect.
