Why A1 Fire-Rated Products Are Essential for Modern Building Safety

In today’s construction industry, safety and compliance are non-negotiable, especially when it comes to fire performance. That’s why A1 fire-rated products have become a top priority for architects, specifiers, and contractors alike. Offering the highest level of fire resistance, A1 materials are classified as non-combustible and do not contribute to fire at any stage – a critical requirement in both high-rise and high-risk developments.

What Makes a Product A1 Fire-Rated?

According to the EN 13501-1 standard, A1 is the highest possible fire classification for building materials. Products with this rating will not ignite, spread flames, or produce smoke or flaming droplets. This makes A1 fire-rated materials ideal for cladding, rainscreens, sheathing boards, and structural framing applications.

At STCS, we specialise in providing a comprehensive range of fully certified A1 fire-rated products, including our new Luxe Clad A1 Façade Systems, helping hand framing, SFS systems, sheathing boards, and membranes. Each product is carefully selected and tested to meet strict UK Building Regulations and to offer peace of mind across the design and build process.
