Board-stacked ceiling & wood-concrete composite

We offer you glulam ceiling elements with acoustic profiling for a visually enhanced look. This attractive design alternative also has improved sound absorption. The possible profiling or joint spacing can be selected between 2, 3 and 4 cm, the standard slot depth is 20 mm with a fixed slot width of 4 mm. Standard elements are produced with a width of 716 mm, resulting in a grid dimension of 720 mm plus the joint. The panels are connected as standard via a butt board inserted in the top rebate (20’/’45 mm). A tongue and groove design of the elements is possible on request. Fitting elements are manufactured as standard elements and must be subsequently tied. The standard element with additional joinery is the billing dimension here.

Wood-concrete composite ceiling

Wood-concrete composite floor slabs are a composite building material made of glulam and concrete. With the help of pin-shaped, glued or form-fitting fasteners, the composite effect of the two building materials is realised. In the composite cross-section, the timber cross-section takes over the load-bearing function in the tension zone and the concrete that in the compression zone. The timber cross-section can be used in the form of a glulam cross-section or as a board stacking element. Due to the composite effect, larger spans can be achieved compared to conventional timber ceiling constructions and the dead weight can be reduced compared to pure concrete constructions. Particularly in areas of increased requirements for serviceability and fire protection, high-performance timber ceiling constructions can thus be realised.
