The ARC T-Barrier Foundation is designed for installation at the foundation level, before brickwork begins, to close the external cavity and provide crucial thermal and acoustic insulation.

Thermal Efficiency: By closing the cavity at the foundation, the T-Barrier Foundation helps to prevent cold bridging, which occurs when heat is lost through the junction between the foundation and the wall. This is essential for maintaining the building's overall thermal performance and energy efficiency, contributing to a lower U-value at this critical junction.

Acoustic Insulation: The T-Barrier also includes mineral wool, which is effective in reducing sound transmission, helping to meet acoustic insulation requirements where the foundation meets the external wall. This is particularly important in preventing noise transfer between different parts of a building or from external sources.

Moisture Control: The T-Barrier Foundation also serves as a protective barrier against moisture ingress at the base of the cavity, safeguarding the structure from potential damp issues that could arise from ground-level moisture.

What is the ARC T-Barrier Foundation?

The ARC T-Barrier Foundation is a thermal and fire barrier designed to prevent the spread of fire and smoke through the foundation walls of a building. It also helps to reduce thermal bridging at the foundation level, improving the building's overall energy efficiency.

How is the ARC T-Barrier Foundation installed?

The ARC T-Barrier Foundation is installed within the cavity of foundation walls, usually at the intersection between the external wall and the foundation. It is designed to be friction-fitted to create a continuous barrier, effectively preventing gaps that could allow the passage of fire or heat.

Where is the ARC T-Barrier Foundation typically used?

This product is used in the foundation walls of buildings, particularly at the junction where the foundation meets the external walls. It is suitable for both residential and commercial buildings, ensuring fire safety and thermal insulation at the foundation level.
