WALLTITE
spray & injection foam insulationWALLTITE closed cell spray and injection foam insulation is manufactured by BASF Polyurethanes at one of their systems houses located in Alfreton, UK. With its low thermal conductivity and high vapour resistivity WALLTITE provides the building owner with superior performance achieving lower U – Values and higher water resistance constructions in an airtight system. This high performance spray insulation system provides a fast and easy apply alternative to more traditional methods of insulating.

WALTITE closed cell foam can be applied directly to the underside of a slate or tile roof covering. In all applications of this nature it is important that the existing roof covering is made water-tight prior to the spraying process. In the event that water passes though the slate or tile covering it will normally lodge between the roof covering and the water resistant foam and so any leak may go undetected. It is also important to not that this process will significantly increase the attachment of the slates or tile covering. With this in mind the likelihood of future alterations to the roof to include the removal of the slates or tiles should be considered.
WALLTITIE is applied between rafters beginning at the eaves and working towards the ridge area in a “flash coat” of less than 10mm in thickness. This ensures that the void between the roof covering and the upper face of the rafter is completely filled. Subsequent coats not exceeding 20mm in thickness are applied until the desired final thickness has been achieved. WALLTITE is BBA Agrément certified for this application.
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 can be applied directly onto a solid masonry wall, around the frame/channel brackets, without the need for traditional adhesion promoters or mechanical fixings.
This method greatly reduces repeating thermal bridges through the insulation caused by either timber studs or metal frames.
The resulting continuous insulation and air barrier system will provide a permanent solution for any ‘hard to treat’ solid wall situation.
WALLTITE can be applied directly onto a solid masonry wall, between 90mm or 140mm timber studs, without the need for traditional adhesion promoters or mechanical fixings.
Mechanical and electrical services can be fixed between the foam and the plasterboard.
WALLTITE guarantees additional support and stability for the whole of the timber frame construction.
The resulting continuous insulation and air barrier system will provide a cleaner, healthier more comfortable environment for any “hard to treat” home situation.
WALLTITE is used to restore the structural stability and reduce the thermal transmittance of existing cavity walls, with masonry inner and outer levels, in which the conventional wall ties have corroded. It is also used in new construction where its superior thermal performance and resistance to flood water is of importance. It has excellent resistance to driving rain and can be installed in all geographical exposure zones.
WALLTITE is also ideal where the need to reduce air leakage is important. The foam seals the cavity, does not shrink or allow air to pass through it, therefore air leakage through the cavity can be reduced to zero. WALLTITE stabilises the wall by adhering to the inner surfaces of the cavity and providing a continuous structural connection between the two leaves.
The system can also be used on random stone walls that form uneven cavities.
