Spray Roof Foam Insulation

Spray Roof Foam Insulation



Welcome to The Eco Home Group. We are installers of high quality spray roof foam insulation.

For all of our customers we are pleased to offer a free home assessment and quotation for our Spray Roof Foam Insulation.


Spray foam roof insulation is one of the most efficient thermal insulation products available on the market today, twice the U 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. Rigid foam insulation is not only one of the most efficient forms of insulation available, saving you money on heating, but also offers:


  • A 25 Year written guarantee on your roof (Lifetime)
  • 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 usable 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.


The Eco Home Group Spray 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.


The Eco Home Group spray roof foam 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.


Spray roof foam insulation


Spray foam roof insulation is a 2 component expanding H20 foam system, consisting of 2 specialised liquid components. These components are contained in steel drums transported to site on our specially equipped vehicles, and are contained on the vehicles throughout the installation process. Once any required roof work is completed our highly trained installers begin the process of setting up and installing the spray foam. Along with the chemical components, our vehicles also contain all the specialised machinery required to install the finished foam product. This machinery is only used by installers trained to set up and dispense the foam system, as the temperature, pressure and proportioning of the machinery are critical to the correct installation of the foam.


When setting up to install foam insulation, the liquids are pumped from their containers into the proportioning area of the machinery, this ensures that the liquid components are sprayed at exactly the right proportion to give a high quality foam with the best insulation values. Once the components are proportioned they are then pumped through to the heating area, again the components must be heated up to the correct temperature to reduce viscosity and deliver a high quality polyurethane foam to the roof. When the components are correctly proportioned and heated they are then pumped down the hose, which again is heated to ensure high quality, to the triggering mechanism which by now will be in the loft. Only when our installers are happy that everything is correct will they begin to install the foam insulation to your roof.

Machinery used to deliver foam insulation.


In order to install the foam insulation to your roof, our installers ensure that the correct air pressure is reaching the triggering mechanism before beginning the installation. When the triggering mechanism is initiated the 2 chemical components are pumped from the hose through the mixing chamber, this mixes the components together before they are pumped at high pressure onto the roof. As the chemicals reach the roof they are still in their liquid form, allowing them to seek and seal gaps and form a continuous bond with the roof, almost immediately they will begin to expand and cure to form a rigid polyurethane foam which adheres to the roof and bonds the roof together to provide extra strength and rigidity.


Once the foam is applied to the roof, within a few minutes it will be touch dry and look more like the finished product. After 24 hours the foam will be completely cured and will form the lasting bond with your roof, allowing us to provide our 25 Year guarantee.
