Roof Insulation

Spray foam roof insulation is one of the most efficient thermal insulation products available on the market today, around twice the value of glass fibre for the same thickness. Polyurethane spray foam is applied as a liquid to the inside of your roof, allowing it to seek and seal any gaps and get into any nook and crannie, before rapidly curing to form a continuous layer of rigid foam insulation which also bonds and seals your roof preventing any slippage of slates/tiles.

  • Keep your loft warmer in winter and also cooler in summer
  • Stop dust and wind blown rain being blown into your loft
  • Prevent old mortar pointing falling off the inside of your roof
  • Turn your loft into a cleaner more useable space
  • Prevent condensation problems
  • Help prevent allergens entering your property
  • Extend the life of your roof

With the increasing amount of concern regarding global warming, one of the most important elements of change identified by the Government is the insulation of older properties. Modern Building Regulations set stringent standards for the insulation needed in new buildings, however older buildings are not covered by these standards yet still produce an enormous amount of this country’s carbon emissions. Therefore the Government has identified older properties as a major area for improvement in our fight against global warming. Using spray foam insulation you can not only drastically improve the insulation in your home, thereby cutting your carbon emissions, you can also improve your peace of mind and gain valuable space at the same time.

Foam insulation applied to roof

Roof Sprayed


Roof foam insulation can be applied either directly onto the inside of slates/tiles, or alternatively to the inside of a roof membrane. When applied directly to the inside of a roof membrane, spray foam insulation will provide excellent thermal insulation without the need for cutting, fitting and sealing which is found with rigid board insulation. When used on the underside of a domestic roof, spray foam insulation will turn your roof from a cold to a warm-roof, allowing you to transform your loft into a more useable space. As the foam is applied to the roof rather than the floor of your loft, the loft space will be warmer, cleaner and more draught-free, making it a much more pleasant area to be used for any purpose. Installing spray foam insulation to your roof allows insulation values to be achieved without the need to install mineral wool insulation above the level of the floor joists, allowing your roof space to have a solid floor to be used for storage without having to install extra joists.

Sprayed foam roof insulation also has the added benefit of preventing both water ingress from the outside and condensation build-up on the inside, increasing the comfort of the loft and the longevity of the roof itself. Due to the nature and installation technique of sprayed foam, condensation – both surface and interstitial – is negligible even in the most severe winter conditions. Coupled with our guarantee on your roof, spray foam insulation should drastically increase the longevity of your roof and comfort of your loft space.
