Product Information
The Flush White Prefinished 1LOS Clear Glazed Fire Door offers contemporary simplicity and certified fire protection in one robust package. Designed for both commercial and light industrial environments, this crisp white model brings a clean, modern finish to corridors, offices, and utility spaces where safety can’t be compromised.

A single clear glazed panel, positioned off-centre for a more architectural look, gives visibility between rooms without breaking the sleek lines of the flush surface. Framed by distinctive raised hockey-stick beading on both sides, the door with its 6mm pyro-glass panel is tested for up to 30 minutes of fire resistance, helping to protect escape routes and shared spaces.
Built with a durable particleboard core and clad in a Prime+ MDF face, this door is supplied prefinished in white, ready to hang straight from the packaging. It can also be top-coated in another colour, giving you full control over the final look. With 18mm hardwood lippings around all four edges, you’ll have up to 12mm of trimming flexibility in each direction for a reliable fit.
Supplied in a full selection of popular imperial and metric sizes, this fire door meets the needs of both refurbishment and new-build projects. Also available in matching internal flush and prefinished oak variants, this door is part of a wider collection designed to maintain consistency across multi-door installations. As always, FSC® (INT-COC-003944.500) mix certification confirms that all timber components come from responsibly managed forests.
Sizing
Offered in both imperial and metric sizes, this 44mm thick fire-rated door includes 18mm lippings on all sides, supporting up to 12mm of trimming per edge to accommodate tight openings or uneven frames.
Sustainability
