Lemahieu Group and LDCwood will be closed from December 22 until January 2, 2026. We will reopen on January 5, 2026.
This architectural masterpiece, aptly named Ter Willer (derived from the local dialect for Waltwilder), is a showpiece for Bilzen. The new hall will provide a significant boost to the cultural and social life in Waltwilder and beyond.
Fire-Retardant ThermoWood® Ayous
For the cladding of the new event hall, LDCwood® ThermoWood® ayous was chosen, which has been treated with Burnblock® to achieve the required fire reaction class.
The fire-retardant treatment with Burnblock® is carried out under pressure in our autoclave. The fire retardant is 100% natural and biodegradable. Moreover, the product is Cradle-to-Cradle™ Gold certified. The fire-retardant treatment ensures the maintenance of the fire reaction class over time, so no re-treatment is necessary.
Durability Class 1
Naturally, ayous is not a durable wood species, but thanks to the thermal modification by LDCwood® in Ostend, this tropical softwood becomes resistant to weather influences and achieves durability class 1. After treatment, the wood has a soft brown color and warm appearance that will gradually turn into a beautiful uniform grey.
LDCwood® guarantees sustainable wood; we only modify wood from sustainably managed forests.
