ARC Eco-Closer - All Thicknesses

ARC Eco-Closer offers up to 60 minutes of fire integrity while effectively closing the cavity around window and door reveals, preventing cold bridging. Its integral DPC helps eliminate moisture, mould, and staining from around windows and doors. The product is insulated with non-combustible rockfibre and is available in cavity widths ranging from 50 to 150mm, with an Eco-Closer Plus option for widths between 150 and 300mm. A single flange version is available for check reveal details, and the product is third-party certificated by IFC.

The ARC Eco-Closer is designed to close the cavity around window and door openings in masonry walls:

Fire Integrity: One of the primary advantages of the ARC Eco-Closer is its ability to provide up to 60 minutes of fire integrity. This means it can effectively prevent the spread of fire through the cavity around window and door openings for up to an hour, enhancing the overall fire safety of the building. In the event of a fire, this time can be critical for allowing occupants to evacuate and for fire services to respond.

Cavity Closure: The Eco-Closer seals the cavity around windows and doors, which is essential for preventing the passage of flames, smoke, and heat in the event of a fire. This closure also helps to maintain the building’s thermal and acoustic performance by eliminating gaps that could lead to heat loss or sound transmission.

Thermal Insulation: By closing the cavity, the Eco-Closer helps to reduce thermal bridging around window and door openings, which can otherwise be weak points in the building's insulation. This contributes to improved energy efficiency and helps to maintain a stable indoor temperature.

Ease of Installation: The ARC Eco-Closer is designed for straightforward installation in masonry walls, making it a practical solution for builders and contractors. Its design allows it to be easily integrated into the construction process, ensuring that cavities are effectively sealed without the need for complex procedures.

What is the ARC Eco-Closer?

The ARC Eco-Closer is an insulated cavity closer designed for use around window and door openings in cavity wall constructions. It provides a thermal break, reducing heat loss and preventing cold bridging while also offering a damp-proof course.

What materials are used in the ARC Eco-Closer?

The ARC Eco-Closer is typically made from a rigid PVCu profile that houses a polystyrene insulation core. This combination ensures thermal efficiency, durability, and ease of installation.

How is the ARC Eco-Closer installed?

The ARC Eco-Closer is installed around window and door openings in cavity walls. It is designed to be easily cut to size on-site and then fitted into the cavity, with the rigid profile providing a secure and neat finish around openings.
