ROOF APPLICATIONS

2.1-new-pitched-roofNew pitched roof
WALLTITE is applied directly to the breathable roofing membrane between timber rafters in tiled or slated pitched roofs. WALLTITE has a measured water vapour permeability, therefore it does not compromise the performance of any breathable membrane, or the timbers to dry out when subjected to periods of solar radiation. The system minimises unwanted air leakage and air infiltration.

WALLTITE can be applied directly onto the underside of existing slate or tiled roofs. It seals any air gaps, preventing the ingress of windblown snow, rain, dust and unwanted air infiltration. The water vapour permeability of WALLTITE permits all roof timbers to dry out following periods of solar radiation. The simulations include building humidity class 4, meteorological data for solar irradiation (direct & indirect) and rainfall for standard reference years, material moisture storage functions, porosity, specific heat capacity and long term projections of material moisture contents.

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 & pitched roofs. WALLTITE automatically provides designers with a more airtight roof. It prevents the ingress of wind blown rain, snow & dust & other forms of airbourne pollution.

WALL APPLICATIONS

New timber frame wall

WALLTITE is applied directly between the studs onto the OSB. The stud is sufficient to meet the recommended elemental U-value. Unwanted air leakage and air infiltration are minimised, and sound attenuation improved. Polyurethane foams are hypoallergenic and contain no fibres or dust and no noxious vapours. Mechanical and electrical services can be fixed between the foam and plasterboard. WALLTITE is quick to install minimising on overhead costs, site storage and waste.

 

Refurbished solid masonry wall with timber frame

WALLTITE can be applied directly onto a solid masonry wall, between 90mm or 140mm timber studs, without the need for traditional adhesion promotors 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 comforable environment for any “hard to treat” home situation.

Refurbished solid masonry wall with steel stud

WALLTITE can be applied directly onto a solid masonry wall without the need for traditional adhesion promotors or mechanical fixings. The foam will engage any light steel framework to provide a more solid, secure wall when compared to other insulation methods. The resulting continuous insulation and air barrier system will provide a cleaner, healthier more comforable environment for any “hard to treat” home situation.

SPECIAL APPLICATIONS

Masonry cavity walls

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. WALTITE stabilises the wall by adhering to the inner surfaces of the cavity and providing a continuous structural connection between the two leaves. Because of the greater thermal performance and the reduced air leakage, WALLTITE outperforms all other forms of cavity fill. It is hypoallergenic and so contains no fibres, dust or obnoxious fumes.

 

External Soffits

WALLTITE in-situ applied PUR insulation foam can be applied directly to the underside of either concrete or steel hollow rib design, ground floor structures. This rigid insulation system does not suffer from air erosion problems and remains permanently adhered even in exposed situations. Its low thermal conductivity maximises head room. Ribbed or waffle shaped soffits can be rapidly, economically and seamlessly insulated with WALLTITE. Any penetrations into the soffit such as ceiling or pipe hangers and cable trays can easily be sealed by a WALLTITE application, preventing heat loss and cold spots.

Concrete slab ground floor

WALLTITE is applied directly to the concrete. Under-floor heating pipes can be fixed to the foam with the normal clips. A layer of tamped or self-levelling screed is applied, usually to a depth of 75mm. The process is extremely quick to apply compared to other methods and the problems of insulation boards lifting are avoided. Site overhead time and material waste from off-cuts are minimised.

Existing timber suspended floor (cellars)

WALLTITE floor insulation is advisable where underfloor heating is installed. The foam barrier separates heated and unheated rooms and in this way, reduces any loss of valuable heating energy into spaces where it is not needed. Rooms with just occasional use benefit from WALLTITE insulation, as the floor heats up more rapidly.
