ARC Soffit Slab - All Thicknesses

• Provides fire stopping within the soffit at the party wall junction
• Excellent thermal and acoustic properties
• One size fits most roof pitches and soffit dimensions
• Manufactured from foil-faced mineral wool

To fill the void within the soffit: The ARC Soffit Slab is an effective solution for filling the void within the soffit, providing essential fire, thermal, and acoustic protection between dwellings.

Fire Protection: The slab is made from rockfibre mineral wool, a material known for its high fire resistance. When installed in the soffit void, it acts as a fire barrier, helping to prevent the spread of flames between adjacent dwellings. The reinforced foil facing enhances this protection by serving as a smoke barrier, ensuring that smoke cannot easily pass through the void.

Thermal Insulation: The ARC Soffit Slab also contributes to thermal insulation between dwellings. By filling the void in the soffit, it helps to reduce heat loss, maintaining energy efficiency and ensuring a stable indoor temperature. This is particularly important in reducing energy costs and improving the overall comfort of the building.

Acoustic Barrier: In addition to its fire and thermal properties, the slab provides acoustic insulation. It helps to dampen sound transmission between dwellings, ensuring greater privacy and reducing noise disturbances. This is especially valuable in multi-occupancy buildings where noise control is a priority.

Custom Fit: The ARC Soffit Slab can be easily cut and shaped to create an exact fit within the soffit void, ensuring that there are no gaps or weak points in the barrier. This adaptability makes it an effective and reliable solution for providing comprehensive protection at this critical junction.

What is the ARC Soffit Slab?

The ARC Soffit Slab is a high-performance insulation product designed for use on the underside of concrete soffits. It provides excellent thermal insulation and fire protection, making it ideal for applications in both residential and commercial buildings.

How is the ARC Soffit Slab installed?

The ARC Soffit Slab is mechanically fixed to the underside of concrete soffits using appropriate fixings. It can be installed with or without an additional vapour control layer, depending on the specific requirements of the project.

What are the key benefits of using the ARC Soffit Slab?

The ARC Soffit Slab provides excellent thermal insulation, reducing heat loss through the soffit and improving the energy efficiency of the building. It also offers superior fire protection, with the ability to resist fire for up to 240 minutes, depending on the thickness of the slab.
