LF5 STRIPS are adhesive perimeter strips in closed-cell expanded polyethylene that isolate the floating screed from walls, pillars and every vertical element. Without them the screed touches the walls and footstep noise passes straight into the structure.
A hot-pressed crease lets the strip fold neatly into an L shape: one part against the wall, one on the underlay. The release film can be removed partly, so the top stays protected and the excess is trimmed after the floor is laid without leaving adhesive on the plaster.
