A straight run of perimeter tape can't wrap an inside or outside corner cleanly, so you're left folding and fudging — and every gap is a spot where bedding mortar can touch the wall and form a sound bridge that carries footfall noise straight into the structure. Blanke TRIBOARD Corners solve it with pre-formed pieces shaped to fit those corners exactly.\u003c\/p\u003e\n\u003cp\u003eChoose the inside corner (CORN-I) for internal wall corners and the outside corner (CORN-A) for external corners and step-downs. Each carries the TRIBOARD uncoupling and impact-sound layer through the corner continuously, so the decoupling stays intact and the perimeter stays sound-isolated.
