The ARC Flexi-Closer is a practical solution for closing the cavity around window and door openings in masonry walls.

Adaptable Design: The Flexi-Closer is designed to accommodate varying cavity widths, making it highly versatile for different masonry wall constructions. This flexibility ensures a snug fit around window and door openings, effectively sealing the cavity regardless of the specific dimensions.

Thermal Insulation: By closing the cavity, the Flexi-Closer helps to prevent thermal bridging, which is the transfer of heat through materials that are more conductive than the surrounding materials. This improves the thermal efficiency of the building, helping to maintain consistent indoor temperatures and reduce energy costs.

Fire Resistance: The ARC Flexi-Closer incorporates a fire-resistant insulated core, which helps to prevent the spread of fire through the cavity around window and door openings. This added safety feature is crucial for meeting building regulations and enhancing the overall fire protection of the structure.

Moisture and Draft Prevention: By effectively sealing the cavity, the Flexi-Closer also prevents the ingress of moisture and drafts, protecting the building from potential dampness and ensuring a more comfortable living environment.

Easy Installation: The Flexi-Closer is designed for easy and straightforward installation, fitting securely into place without the need for additional fixings. This ease of installation makes it a convenient choice for builders and contractors, ensuring that cavities around window and door openings are properly sealed during the construction process.
