✅ Why Choose Our Fire Rated Decking System?

🔥 A1 Fire Rated Balcony Decking

Our porcelain decking boards are made from vitrified extruded ceramic, achieving the highest Euroclass A1fl-s1 fire rating. Fully non-combustible, this system meets all UK building regulations for use in high-rise residential and commercial developments—making it a reliable solution for fire rated balcony decking.

🪵 Natural Wood Look, Zero Maintenance

Porcelain boards offer the aesthetic of real wood with none of the upkeep. Resistant to staining, fading, and weathering, they maintain their finish for decades without painting or sealing.

🧱 Robust Aluminium Substructure

The Aslon aluminium joist system provides a stable, corrosion-resistant base that is quick and easy to install. Aluminium joists remain straight over time—unlike timber alternatives—ensuring a long-lasting, level surface.
