About TECSOUND TUBE S
TECSOUND TUBE S is a dedicated wrap for building soil/waste downpipes (bajantes), cutting drainage noise and structure-borne transmission to rooms below and alongside.
It combines the high-density TECSOUND membrane with a high-tenacity polyester non-woven felt, plus two self-adhesive bands that speed installation and seal the overlap — no separate adhesive needed.
Suitable for PVC, fibre-cement and metal pipes, it provides an insertion loss of IL 13–15 dBA (EN 14366, flow 1–4 l/s).
Applications
