Cavity wall insulation

WALLTITE cavity wall foam insulation is used to reduce the heat loss of existing and new build cavity walls consisting of masonry inner and outer leaf construction. Installed as a liquid through a pattern of 12mm pre-drilled holes it expands within the cavity to gently fill each void eventually setting as a rigid polyurethane high-density insulation. WALLTITE seals the cavity thereby preventing air leakage. The increased airtightness effect adds to the systems already superior thermal performance helping to reduce energy bills and creating a more comfortable living environment. WALLTITE insulation is also used to restore the structural stability of existing cavity walls in which conventional wall ties have corroded and in new build and reform construction where its resistance to flood water is of importance. WALLTITE stabilises the wall by adhering to the inner surfaces of the cavity and providing a continuous structural connection between the two leaves. It has excellent resistance to driving rain and can be installed in all geographical exposure zones.

Timber frame insulation

WALLTITE foam insulation is spray applied directly between timber studwork onto the OSB at the required thickness. Ordinarily a 25mm cavity will remain between the insulation and vapour control layers to allow for services. 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. WALLTITE Polyurethane spray is hypo allergenic and so contains no fibres or dust and no noxious vapours. BASF WALLTITE is very quickly installed by Foam Master contractors sing specialist equipment.

Masonry wall insulation – steel stud

WALLTITE spray foam insulation can be applied directly onto a solid dry masonry wall, between steel studwork fixed floor to ceiling. This allows for a layer of WALLTITE to remain unbridged by studwork thereby helping to reduce u-values further. The foam will engage any light steel framework to provide a more solid, secure wall when compared to other insulation methods. Ordinarily a 25mm cavity will remain between the insulation and vapour control layers to allow for services. WALLTITE guarantees additional support and stability for the whole of the wall construction. The resulting continuous insulation and air barrier system will provide a cleaner, healthier more comfortable environment for any “hard to treat” home situation.

Masonry wall insulation – timber stud

WALLTITE spray foam insulation can be applied directly onto a solid dry masonry wall, between timber studwork either fixed directly to the wall or anchored floor to ceiling. The latter method allows for a layer of WALLTITE to remain unbridged by timber thereby helping to reduce u-values even further. Ordinarily a 25mm cavity will remain between the insulation and vapour control layers to allow for services. 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.

New pitched roof insulation

WALLTITE spray foam insulation is applied directly to the underside of breathable roofing membrane between timber rafters in tiled or slated pitched roofs. The spray insulation material can be installed to any thickness to achieve preferred u-values and demonstrates an impressively high level of airtightness thereby adding to the systems superior thermal performance. WALLTITE has a measured water vapour permeability and so does not compromise the performance of any breathable roof membrane. WALLTITE is installed by trained and accredited Foam Master contractors throughout Ireland using specialist spray foam equipment. Certain refurb scenarios may involve a non-breathable roof membrane. A rafter-slide it installed to the underside of the roofing felt to act as a separator between the foam insulation and the felt underside. This allows for a 50mm ventilated airgap as required by building regulations.

Existing pitched roof insulation

WALLTITE spray foam insulation is applied directly to the underside of breathable rafter slide between timber rafters in tiled or slated pitched roofs. The spray insulation material can be installed to any thickness to achieve preferred u-values and demonstrates an impressively high level of airtightness thereby adding to the systems superior thermal performance. WALLTITE has a measured water vapour permeability and so does not compromise the of the breathability of the roof structure. WALLTITE is installed by trained and accredited Foam Master contractors throughout Ireland using specialist spray foam equipment.. The rafter slide is installed to the underside of the existing roofing felt to act as a separator between the foam insulation and the felt underside. This allows for a 50mm ventilated airgap as required by building regulations.

Soffit insulation

WALLTITE spray applied foam insulation can be applied directly to the underside of either concrete or steel hollow rib design, soffit structures. This rigid polyurethane insulation system is airtight and remains permanently adhered to the substrate even in exposed situations. BASF WALLTITE spray foam has a thermal conductivity 0.025 W/mk thereby achieving the maximum insulating performance for a given thickness. Ribbed or waffle shaped soffits can be rapidly, economically and seamlessly insulated and made airtight with WALLTITE foam. 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 by thermal bridging. WALLTITE spray foam is installed by trained and accredited Foam Master contractor using specialist spray machinery and is Class 1 surface spared of flame rated.
