Walltite CL100 Spray Insulation

Airtight and Fire Retardant Spray Insulation

WALLTITE closed cell spray foam insulation is manufactured by BASF Polyurethanes  at their manufacturing facility in Alfreton, UK. It provides an efficient insulation solution for commercial and domestic buildings. With its low thermal conductivity and high vapour resistivity WALLTITE provides the building owner with superior performance combined with complete airtightness and a Class 1 Fire rating.

This high performance spray insulation system provides a fast and easy apply alternative to more traditional methods of insulating and when cured gives a seamless airtight system that will contribute significantly to the overall heat retention performance of the building envelope. WALLTITE is a continuous spray foam that is rapidly applied by BASF Foam Masters and is 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. Each FoamMaster must undergo initial training at Alfreton and subsequent site audits in Ireland.

Key Benefits of Walltite Cl100

WALLTITE® CL100 Closed cell insulation for internal roofs, floors and walls providing a seamless airtight solution, which is spray applied to offer superior all round performance compared to conventional insulations.

Energy efficiency

Spray foam is a speedy, efficient insulation solution coupled
with significantly lower U-values than other conventional
insulation materials.
Spray foam has a thermal conductivity as low as 0.025W/mK.

Air tightness

The continuous spray leaves a minimal amount of surface area
without insulation resulting in an airtight building envelope of low
permeability, and without the need for supplementary material.
The foam is fast to apply and quick to cure. Spray foam
therefore offers the specifier an all in one solution to meet and
exceed latest Building Regulations requirements.


By virtually eliminating air leakage, spray foam helps control the
movement of vapour and moisture throughout the building,
reducing the risk of condensation and mould. Sustainable over the
life span of the building, spray foam can even prolong the
buildings life as it protects against premature deterioration of
building materials.

Design freedom

Spray foam 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.

Occupier comfort

For building occupiers, spray foam makes a significant
contribution to a comfortable indoor climate by creating a
draft free environment that prevents the infiltration of pollutants,
toxins and allergens.


BASF spray foam is only installed by BASF-trained professionals.
A nationwide network of Approved Contractors is available
throughout the UK and Ireland
