Full Product Overview

The DOLLE REI 60 Fire-Resistant Loft Ladder – 1150 × 550mm is a premium folding timber loft ladder designed for properties where certified fire resistance, thermal performance and a more compact ceiling opening are required.

The complete assembly provides 60 minutes of fire resistance with an REI 60 classification and testing to EN 13501-2. At the centre of the design is a substantial 76 mm insulated trapdoor containing 70 mm of non-combustible Rockwool stone wool.

This insulation contributes to both the fire performance and a component-tested U-value of 0.94 W/m²K, while EN 12207 Class 4 airtightness helps reduce unwanted air leakage through the loft opening.

Despite its narrower 1150 × 550 mm opening, the ladder retains a comfortable three-section timber design with 12 solid beech treads measuring 383 mm wide × 83 mm deep.

The white CPL-coated trapdoor provides a clean, durable finish when closed, while the compact opening makes this model particularly useful where available ceiling width is restricted.

With a 150 kg maximum load, FSC® certified timber and manufacture according to EN 14975, the REI 60 combines certified fire performance with practical everyday loft access.
