DOLLE RF90 is fire resistant for 90 minutes and complies with EN 4102-2. The hatch is insulated with 50mm rockwool + 10cm gypsum. The hatch has a beautiful finish in white HDF plate with hidden hinges and has a high-quality lock. The DOLLE RF90 Loft ladder is made of a sturdy quality pine with 12 non-slip beech steps with black non-slip plastic feet to protect the floor. The 19 cm high housing is equipped with sealing strips to prevent heat loss. The wooden ladder is easy to operate, high quality, stable and easy to use.
It is important that a house is built in such a way that the structure is protected for a short period of time in the event of a fire. Building regulations therefore set different requirements for the fire resistance of construction parts in a building or home. That is why we test our fire-resistant staircases according to the highest requirements in Europe and they comply with EN 4102-2. DOLLE RF90 has a fire resistance of 90 minutes.
A fire-resistant staircase is tested in a fire test in which the staircase is built into a combustion chamber and exposed to a real-life fire situation. DOLLE's fire-resistant ladders have been tested according to the new common European method for testing the fire resistance of building components. The DOLLE fire-resistant staircase has been tested at the MPA Braunschweig Institute in Germany.
The new European fire requirements are described for the fire-resistant attic stairs:
R (resistance) carrying capacity during fire.
E (integrity) ability to keep out flames and gases.
I (insulation) ability to keep warm outside.
After the classification, the DOLLE RF90 indicates the period for which the loft ladder is fire-resistant, so that the fire-resistant stairs are fire-resistant for 90 minutes.
