A unique material, RETICULATED WOOD® "Reticulated wood®". Cross-linked wood composite, a family defined by the CSTB (Centre Scientifique et Technique du Bâtiment), during the elaboration of the NF standard. Cross-linked wood® is obtained using an exclusive process: the dual action of heat (200°C) and pressure (450 t) causes the resins contained in a mixture based on beech flour to react.

The NF standard for toilet seats (NF XP D12-207 and NF 240) held by OLFA was developed by AFNOR and CSTB in collaboration with toilet seat manufacturers and ceramists.

Fire / Smoke classification of OLFA cross-linked wood Reaction to fire: M2 according to NF P92-507 Smoke emission: F1 according to NF F 16-101 and NF F 16-102

Resistance in humid environment Over 200 hours in an oven at 50°C and 99% of relative humidity. Total immersion in water heated to 65°C for more than 2 hours (NF standard requirement = 1 hour).

Mechanical resistance Mechanical endurance: 100,000 cycles, much higher than the 30,000 cycles required by the NF standard. Static loads 200 Kg (NF standard: 150 Kg). Dynamic loads 75 Kg for more than 60,000 cycles (NF Standard: 30,000 cycles).

Chemical resistance Resistant to sulphamic acid, uric acid, caustic soda, bleach and various products on the market. Unaffected by eosin. Required by the NF standard.

Maintenance Cleaning: Sponge cleaning with standard toilet seat cleaning agents. It is recommended to lift the seat when cleaning the bowl. The use of strongly chlorinated substances, acids and abrasive products is not recommended.
