It’s important that a house is built so that the structure is protected for a short time in the case of a fire. Therefore, the building regulations set several requirements regarding the fire resistance on constructions parts in a building or house. This includes a standard for loft ladders. Therefore, we test our fire-resistant loft ladder program according to the highest demands in Europe and they comply to EN 13501-2. DOLLE REI 45 has a fire resistance of 45 minutes.
A fire-resistant loft ladder is tested in a fire test where the loft ladder is built into a fire chamber and exposed to a real-life fire situation. DOLLE's fire-resistant loft ladders have been tested according to the new common European method for testing fire resistance for building parts REI. The fire-resistant loft ladder from DOLLE REI 45 has been tested at MPA Braunschweig institute in Germany.
The new European fire requirements are described from the loft ladders:
R (resistance) carrying capacity during fire.
E (integrity) ability to keep flames and gases out.
I (insulation) ability to keep warm out.
After the classification, the time period for which the loft ladder can withstand fire is indicated by the DOLLE REI 45 so that the fire-resistant loft ladders are fireproof for 45 minutes.
All loft ladders from DOLLE are tested in accordance with EN 14975.
