Description

Closed cell spray foam insulation designed for external walls, floors, roofs and soffits and provides a seamless airtight insulation solution. Unlike conventional insulation materials, Walltite is spray applied by a nationwide network of trained and accredited BASF Foam Master contractors.

The spray foam makes a significant contribution to a comfortable indoor environment for building occupiers by creating a draft free climate and reducing the overall rate of heat loss from a building. It provides the building owner with superior performance due to the combination of insulation and complete airtightness.

Walltite is a continuous spray foam that is fast to apply and quick to cure, leaving a minimal amount of surface area without insulation. The result is an airtight building envelope of low permeability, without the need for supplementary material. The closed cell structure helps control the movement of vapour and moisture throughout the building, reducing the risk of condensation and mould. It is sustainable over the life span of the building and can even prolong the buildings life as it protects against premature deterioration of building materials.

Features and benefits:

  • Insulation with no joints or gaps.
  • Maximum insulating performance at minimum thickness.
  • Insulation of components in hard to treat areas.
  • Excellent adhesion to the substrate.
  • Prolongs the life of buildings.
  • Rapid installation times.
  • Safe, professional installation.
  • Increases comfort in the home.
  • Low material weight.
  • Quality assurance through self-monitoring.
  • Easy to transport and store.

Applications:

  • New pitched roofs.
  • Existing pitched roofs.
  • Rooms within in a roof.
  • New timber frame walls.
  • External soffits.
  • External roofs.
  • Refurbished masonry walls (timber frame).
  • Refurbished masonry walls (steel stud).
  • Concrete slab ground floors.
