Grayson Building Products are delighted to introduce FireBlox™ Plus, the next generation of cavity barriers specifically formulated for masonry facades.
FireBlox™ Plus is a new and improved version of the extremely popular FireBlox™ close-state cavity barrier.
It is a non-ventilated cavity barrier made from A1 non-combustible plain stone mineral wool. It is suitable for use within external wall cavities of up to 450mm and is designed for both masonry-to-masonry and SFS-to-masonry applications.
Its standard slab size (1200mm wide x 1000mm long x 100mm deep) is designed to minimise wastage when installed into popular cavity sizes. Manufactured from mineral fibres, they are structured to facilitate the required 3mm-5mm compression, making it ideal for ‘green mortar’ applications. The barriers standard foil casing prevents the spread of cold smoke. This market-leading two-hour solution is fire-rated for up to 120 minutes (EI120).*
The system has undergone some of the most wide-ranging and rigorous testing to date, with multiple tests, numerous SFS build-ups, lintel and masonry support interfaces and balcony stub details. FireBlox™ Plus also has full test data for smaller cavities (20mm-70mm) with just a 3mm compression.
Designed for masonry applications, FireBlox™ Plus is more compressible than previous products, whilst losing none of its market-leading performance. Making is ideal for green mortar installation.
FireBlox™ Plus has, without a doubt, raised the bar within non-ventilated cavity barriers.
