The versatility of in-situ applied WALLTITE® insulation foam makes it an ideal material for use in loft conversions.
It can be applied to external solid or cavity walls, separating or party walls, knee or side walls, flat and pitched roofs.
WALLTITE® automatically provides designers with a more airtight roof. It prevents the ingress of wind blown rain, snow and dust and other forms of airborne pollution.
BBA Certificate No. 11/4816.
WALLTITE® has undergone various performance tests. Certificates are available on request.
Existing pitched roof, ceiling at rafter line
WALLTITE is applied between the rafters in sloping ceiling areas, either directly onto the underside of slates or tiles, or onto a membrane of low vapour resistivity.
Plasterboard is then fixed to the face of the rafters.
Habitable space: plasterboard and skim/VCL with taped joints VCL to be carefully cut and sealed around struts, ceiling joists and penetrations); batten/counter batten rafters as necessary to achieve insulation depth, confirm rafter strength sufficient to receive counter battening and boarding if required.
Loft space only, non habitable: insulated between and over rafters to achieve target U-value. WALLTITE® may remain exposed.
