WALLTITE® is applied directly between the studs onto the OSB. The stud depth should be sufficient to meet the recommended elemental U-value.
Unwanted air leakage and air infiltration is minimised and sound attenuation improved.
Polyurethane foams are hypo allergenic and so contain no fibres or dust and no noxious vapours. Mechanical and electrical services can be fixed between the foam and the plasterboard. WALLTITE® is very quick to install minimising on overhead costs, site storage and waste.
WALLTITE® has undergone various performance tests. Certificates are available on request.
Allow for differential movement at ALL openings, i.e. at window cill and window heads, as recommended by the timber frame manufacturer/UKTFA/TRADA: to accommodate differential movement and provide weather resistant and durable joint.
