WALLTITE®
Spray Foam Insulation

External soffit insulation

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.
