Floor Insulation

As heat escapes from the house, something must replace the warm air, and in many cases cold air is drawn in from under suspended floors making a cold draughty house.If access permits, we can spray Icynene directly to the underside of the flooring; a depth of 500mm or more is required. If there is very little space under the floor then one approach is to install a sub-floor, which can be installed by lifting some of the floor boards and fastening a thin plywood sheet into battens nailed to the sides of the joists, we can then install the Icynene through the gaps in the floor where the boards have been lifted. 

Extra joinery work must be allowed for if a sub floor has to be installed, but the end results are worth it. 

Depending on the scope of any renovation work, one solution might be to 'wrap' the exposed joists with a breathable membrane, such as building paper, to create a substrate onto which the Icynene can be sprayed directly from above. We are happy to offer guidance to joiners and builders to help deliver the best solutions.
