The SoliD perforated folded underlay is designed to optimize heat distribution for heated flooring systems. This pink-colored underlay comes in a roll with a total area of 8.4 m2, featuring a length of 8 m and a width of 1.05 m, though it is folded to a width of 0.5 m for easier handling. With a slim thickness of 1.8 mm and dimensions of 1050x500 mm per section, the material's perforated surface ensures that warmth spreads evenly across the floor. This makes it a practical choice for anyone installing underfloor heating who wants to avoid cold spots and ensure a consistent temperature throughout the room.
