btf-Flüstermatte 8mm

Art. no. 2514 with a Separating Layer; Art. no. 2517 without a Separating Layer

The Innovation with Reduction in Impact Sound!

The most convincing arguments for the btf-SILENT LAYER MAT are its minimal thickness and above-average sound insulation, even with the high load resistance of up to 4 kN/m².

The extremely thin and light btf-SILENT LAYER MAT is laid directly from the roll. The btf-SILENT LAYER MAT already comes with a separating layer (ca. 10 cm overlap). The separating layer is to be made of PE foil of at least 0.1 mm thickness or glass matting of at least 50 g/m³ surface weight. The btf-SILENT LAYER MAT are to be laid close together and fixed in place with the appropriate adhesive tape (such as btf connection strips) so that there are no gaps in the joint area. In order to possibly avoid sound bridges on the rising walls, appropriate insulation strips are necessary.
