Key Features & Benefits

Enhanced Durability: The patented acetylation process makes the timber highly water-resistant, rot-resistant, and prevents moisture absorption. Accoya timber is from sustainable sources and outperforms traditional hardwoods.
User-Friendly Operation: Designed for easy, single person use. StormMeister Accoya Timber Flood Doors are the only timber flood doors compliant with Building Regulations for thermal efficiency and the Building Safety Act 2022.
Flood Protection: Flood tested to 400mm, and flood sealed all the way around the door for ongoing flood and storm protection.
Compliance: StormMeister® Accoya Timber Flood Doors comply with BS EN 12217 for door handle operating forces, enabling usability and accessibility.
Custom Configurations: Available in custom sizes and designs to suit your requirements. Can be manufactured to replicate existing doors in conservation areas.
Bespoke Finishes: Can be finished to a range of wood stains, coloured to your choice, or colour finished to match your existing colours. Treated with Remmer (Remmers.co.uk), our Accoya doors use a five-coat system including an end grain sealer to block the pores in the timber structure and prevent the wood from absorbing any water. This protects the timber and the paint. The topcoats are water-based UV resistant paint which is specifically formulated for our Accoya timber products. We use SW-900 Pre Primer (deluge) colourless so we can stain or colour, M-425 Weis ZW-425 Primer (in white, RAL 9016) or coloured to suit the top coat and DW-601 Aquastop Top Coat, Sheen level 35 is standard. Colours available are RAL Classic, Little Greene and Farrow and Ball.
Ease of Access: Available as inward or outward opening, and can be provided with Part ‘M’ compliant low threshold for wheelchair access.

Technical Information

Accoya is widely recognised as the benchmark in the timber industry for its outstanding performance and sustainability. No other wood matches its unique combination of exceptional durability, dimensional stability, and versatility.

Sustainably sourced from fast-growing forests and with a low whole-life carbon footprint, Accoya supports a circular, bio-based economy and stands as one of the most genuinely sustainable building materials available today.

Using a precise, patented acetylation process, Accoya wood is transformed at a molecular level. By treating the timber with acetic anhydride under carefully controlled heat and pressure, the process replaces water-attracting hydroxyl groups with moisture-resistant acetyl groups. This advanced modification dramatically improves the wood’s resistance to moisture, swelling, and decay.

The result is an ultra-high-performance, highly stable timber that is ideal for demanding applications — including flood protection products, cladding, decking, windows, doors, and outdoor structures.
