New Timber Frame Wall Insulation

Our timber frame wall insulation ensures that unwanted air leakage and infiltration in your residential or commercial property is minimised, whilst sound-proofing is improved.

Polyurethane foams such as ours are hypo allergenic, which means that they contain no fibres, dust or noxious vapours. Mechanical and electrical services can be fixed between the foam and the plasterboard, so the efficiency of your building is never compromised. Spray foam insulation is very quick to install, minimising on overhead costs, site storage and waste - the perfect solution for improved thermal efficiency!
