DOLLE REI 60 has a fire-resistance of 60 minutes and complies with EN 13501-2 and has a component-tested U-value of 0.77 W / m² · K, tested by Technological Institute. Standard in 2 sizes. For other sizes see made to measure.
DOLLE REI 60 has a fire-resistance of 60 minutes and complies with EN 13501-2. The trapdoor is insulated with 70 mm rockwool plate, which is made of non-combustible, moisture and water-repellent Rockwool stone wool.
The 76 mm thick trapdoor of the DOLLE REI 60 vario is insulated with 70 mm rockwool plate, which is made of non-combustible, moisture and water-repellent Rockwool stone wool. This insulation not only withstand fire but also hold onto heat in winter and reduce heat efficiently in the living area during summer. The trapdoor is coated with a robust laminate CPL which is significantly more abrasion, scratch and impact-resistant than other surfaces. The secret lies in the top layer, which consists of melamine resin. It withstands light scratches as well as normal dirt, it's solvent and heat resistant, smudge-proof and easy to clean. The trapdoor fits discreetly into the ceiling and remains in pristine condition. The white CPL surface is UV-resistant and therefore maintains the bright white colour for a long time.
DOLLE REI 60 wooden loft ladder is made in a solid quality of pine with 12 non-slip beech treads with black non-slip plastic feet to protect the flooring. The 19 cm high casing comes with sealing strips to prevent heat loss. The wooden ladder is easy to operate, high quality, stable and easy to use.
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 60 has a fire resistance of 60 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 60 has been tested and is certified at DBI (Danish Fire and Security Technical Institute.)
