System 8000W
For adjustable height 95 – 470 mm, excl. Floor covering.
A subfloor system made of a specially developed wooden beam, primarily for CLT and other types of wooden flooring, which provides effective step and airborne sound insulation for different sound classes. This wooden beam is much more dimensionally stable than a normal wooden joists. Provides a dry and fast installation where many installations can be hidden in the space between the CLT and the upper floor. An even more environmentally friendly alternative than our steel girders with a 50% lower CO2 impact compared to concrete screeds of various kinds.
