It has not only soundproofing properties, but is also a significant insulator inside the room, 20 mm XPS is enough to compare in terms of thermal insulation with 370 mm brickwork, 180 mm wood and 270 mm cellular concrete. In addition, polystyrene serves as a waterproofing layer for MDVP and does not allow it to get wet (when sealing the joints between the panels). Therefore, the Comfort panel perfectly combines both insulation and waterproofing - it can be safely used in wet rooms: bathrooms, washing rooms and showers. The panels are fastened with soundproofing dowels or ordinary dowels without flats + self-tapping screws with a press washer. RPG BAND 100mm tape and ACR 130 ACR 198 compounds are used to level the joint between the panels and waterproofing. • Item: RPG4CF28#2/1250 • Weight, kg: 9.48 • Volume, m3: 0.027 • Area, m2: 0.74 • Name of material 1: Base 1 • Thickness, mm, of material 1: 6 • Name of material 2: FIBERBOARD • Thickness, mm, material 2: 12 • Name of material 3: Membrane • Thickness, mm, material 3: 4 • Name of material 4: Base1 • Thickness, mm, material 4: 10 • Reinforcement: 2 sides • Edge shape: quarter • Color: blue/brown Advantages High heat and sound insulation characteristics. Protection from air and impact noise - 20 dB. Easy installation of the material, it does not require the construction of a frame, even non-specialists can cope. The shape of the edge of the panel "in a quarter" (overlapping), this solution allows the material to fit together as tightly as possible, eliminating the passage of noise at the joints of panels. Has a light weight (for walls no load). Creating a ready-made base of walls for finishing on any surface. Versatility of application - noise insulation of both walls and ceilings. Resistance to high humidity and fungus formation on walls. Suitable for noise and heat insulation in wet rooms: bathrooms and sanitary facilities. High tensile strength under high loads. The material has no linear expansion.
