Efficient, environmentally- friendly insulation for your new or existing home

With heat lost easily through a poorly insulated roof, we recommend opting for airtight insulation to provide the best level of energy efficiency for your new build. Icynene spray foam can be installed far quicker than traditional insulation and offers an exceptionally high level of airtightness - eliminating convected heat loss. To achieve the u-value required by current building regulations, a 150-275mm layer of foam is required.

Typically, new timber framed houses are built with a 145mm x 45m frame which is filled and trimmed before plasterboard is fitted. However, this often neglects the service zone for cables and structural elements such as cripple studs and lintels. To address this problem and improve the efficiency of your timber frame our technical team recommends installing 45mm x 50mm timber branders so we can install 45mm of insulation over all structural timbers, which greatly improves the performance of your building.

For suspended floors, 100-150mm of Icynene spray foam applied to the underside of the floor delivers full airtightness eliminating the draw-in of cold air completely.

Traditional homes usually have open attics - which are straightforward to insulate - or rooms in the roof space with sloping ceilings (coombs) and dormers - which almost always creates a cold house.

We insulate open attics with a nominal 100-150mm of Icynene sprayed on to the underside of the sarking boards and the interior gable walls. This creates a warm roof space and improves the energy performance of your home substantially.

Attic rooms and loft conversions can be more difficult to treat - as traditional insulation has usually not been installed in the coombs - but Icynene can easily be sprayed into these hard to reach areas either from the small attic space above or by making access in the ceiling lining. Vertical walls and dormer windows can also be treated with the removal of selected linings.

In existing houses cold air being drawn in from beneath suspended floors is caused by heat escaping from the roof and walls above. Access-permitting, Icynene insulating foam can be applied directly to the underside of your flooring. Where there is little space under the floor, a sub floor can be installed with Icynene applied where the floor has been lifted.

From solid masonry walls with lath and plaster linings to poured concrete, brick cavity, solid block, steel frame, and modern timber frames, there are numerous different methods of wall construction. To assess the suitability of installing Icynene spray foam insulation our technical team will conduct a thorough survey, assessing the wall build, condition and humidity levels to ensure that installing Icynene is the correct measure for your home.

Applying spray foam insulation to modern timber frames is relatively straightforward, requiring existing insulation to be removed. For those with solid masonry walls with lath and plaster linings, our skilled spray team can inject Icynene through 13mm holes drilled in a grid pattern from in the room.

Icynene spray foam will insulate your walls better than any existing insulation, with huge long term financial and environmental benefits, so it is something we recommend to those looking to improve the energy efficiency of an existing property.
