Effective solution for closing the cavity around window and door openings:

Effective Cavity Sealing: The ARC Contract Closer is specifically designed to close the cavity around window and door openings, ensuring that gaps are sealed. This prevents drafts, moisture ingress, and potential thermal bridging, which are critical for maintaining the building’s overall energy efficiency and comfort.

Thermal Performance: By closing the cavity, the Contract Closer helps to minimise heat loss around window and door openings. This is essential for improving the thermal performance of the building, contributing to energy savings and a more stable indoor environment.

Fire Protection: The Contract Closer provides an additional layer of fire protection by including an insulated core that helps to resist the spread of fire through cavities. This feature is particularly important in meeting building regulations and enhancing the safety of occupants.

Versatile Application: The ARC Contract Closer is suitable for use with a variety of window and door frame types and can be adapted to different cavity widths. This makes it a versatile solution for various building projects, ensuring that the closure is effective regardless of the specific construction details.

Easy Installation: Designed for straightforward installation, the Contract Closer can be quickly and securely fitted around window and door openings. This ease of use ensures that the cavities are properly sealed without adding complexity to the construction process.

• What is the ARC Contract Closer? - The ARC Contract Closer is a cost-effective cavity closer designed to provide thermal insulation and damp-proofing around window and door openings in cavity walls. It helps to prevent cold bridging and condensation, improving the building's energy efficiency.
• What materials are used in the ARC Contract Closer? - The ARC Contract Closer consists of a rigid PVCu profile encasing a core of polystyrene insulation. This combination ensures both durability and effective thermal performance.
• How is the ARC Contract Closer installed? - The ARC Contract Closer is installed by positioning it around window and door openings in cavity walls during construction. It can be cut to the required size and fixed using masonry fixings or adhesive. Detailed installation instructions are provided to ensure proper fit and performance.
