ARC Eco-Closer PLUS - All Thicknesses

The product provides up to two hours of fire integrity, effectively closing cavities around window and door reveals in larger cavities up to 300mm. It prevents cold bridging and helps eliminate moisture, mould, and staining from around windows and doors. The insulation is made from foil-faced non-combustible rockfibre, and the plastic profile serves as a damp proof course (DPC), making it suitable for cavity widths up to 300mm.

ARC Eco-Closer PLUS closes wider cavities around window and door openings in masonry walls, providing up to two hours fire integrity:

Extended Fire Integrity: The ARC Eco-Closer PLUS provides up to two hours of fire integrity, making it particularly suitable for applications where enhanced fire resistance is required. This extended protection helps prevent the spread of fire through the cavity around window and door openings, giving more time for safe evacuation and fire service intervention.

Wider Cavity Compatibility: Unlike standard cavity closers, the Eco-Closer PLUS is designed to accommodate wider cavities commonly found in modern masonry wall constructions. This makes it a versatile solution for a range of building designs, ensuring that even larger gaps are effectively sealed.

Cavity Closure: By closing the cavity around windows and doors, the Eco-Closer PLUS helps to prevent the passage of fire, smoke, and heat. This not only enhances fire safety but also maintains the building’s thermal and acoustic integrity, reducing heat loss and noise transmission through these critical junctions.

Thermal and Acoustic Performance: In addition to fire protection, the Eco-Closer PLUS also helps to reduce thermal bridging around window and door openings. This improves the building’s energy efficiency and contributes to a more comfortable indoor environment by minimising heat loss and sound transmission.

Ease of Installation: The Eco-Closer PLUS is designed for straightforward installation, even in wider cavities. Its flexible design allows it to be easily integrated into the construction process, ensuring a secure fit that provides both fire safety and insulation benefits.

What is the ARC Eco-Closer PLUS?

The ARC Eco-Closer PLUS is an advanced insulated cavity closer designed for use around window and door openings in cavity wall constructions. It offers enhanced thermal performance to prevent cold bridging and reduce heat loss, contributing to better energy efficiency in buildings.

What is the difference between ARC Eco-Closer and ARC Eco-Closer PLUS?

The ARC Eco-Closer and ARC Eco-Closer PLUS are both insulated cavity closers designed for use around window and door openings, but the PLUS version offers superior thermal performance. While the standard Eco-Closer provides effective insulation and is suitable for general residential and commercial projects, the Eco-Closer PLUS features enhanced insulation materials to achieve lower U-values, making it ideal for energy-efficient and sustainable building projects. The PLUS version is particularly beneficial for applications where higher thermal efficiency is required, such as in low-energy or passive house constructions.

How is the ARC Eco-Closer PLUS installed?

The ARC Eco-Closer PLUS is installed similarly to the standard version, around window and door openings in cavity walls. It is cut to size on-site and fitted into the cavity, providing a secure thermal break and damp-proof course.

In what types of construction projects is the ARC Eco-Closer PLUS typically used?

The ARC Eco-Closer PLUS is particularly suited for projects that require enhanced energy efficiency, such as low-energy homes, passive houses, and other sustainable building initiatives.
