Blanke TRIBOARD handles both in a single 1\/8\" layer — it uncouples the tile from the subfloor and it cuts impact noise by up to 17 dB.\u003c\/p\u003e\n\u003cp\u003eAs an uncoupling membrane, it isolates in-plane movement between the substrate and the tile, so when the subfloor shifts or cracks, that stress doesn't transfer into your finished floor. As an impact-sound layer, it's tested to DIN EN ISO 140-8 for up to 17 dB of footfall-noise reduction — the kind of number that matters in condos, multi-level homes, and anywhere a hard floor sits over occupied space. And it does it thin: just 1\/8\" of added height, with low mass, so it fits under doors and at transitions where thicker systems won't.\u003c\/p\u003e\n\u003cp\u003eDon't let the thinness fool you: it has high compressive strength for traffic loads up to 104.4 psf, so it holds up under real use with ceramic and natural stone. It bonds in thin-set over concrete, wood, screeds, old tile, radiant floors, and more (load-bearing, dry, and flat), and it's a very low-emission, odorless product.
