New pitched roof
Description
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.
Certification
BBA Certificate No. 11/4816.
WALLTITE has undergone various performance tests. Certificates are available on request.

Features and benefits
- Energy efficiency - the continuous spray leaves a minimal amount of surface area without insulation resulting in some cases, a 30% decrease in thermal transmission and an airtight building envelope of low permeability without the need for supplementary material.
- Sustainability - sustainable over the life span of the building, WALLTITE can even prolong the buildings life as it protects against premature deterioration of building materials.
- Design freedom - WALLTITE also provides the specifier with complete design freedom as the spray foam adapts to the shape of the substrate providing an ideal solution for insulating difficult areas such as profiled and curved roofs. The product is self-adhesive and stays fully bonded to the substrate, preventing any possible detachment, common with other types of insulation.
- Occupier comfort - for building occupiers, WALLTITE makes a significant contribution to a comfortable indoor climate by creating a draft free environment that prevents the infiltration of pollutants, toxins and allergens.
- Reliability - WALLTITE is only installed by trained professionals approved by BASF in the UK.
