Application of Reed Panels as Floor Insulation

General Information

In civil engineering we generally distinguish between unfinished and finished floor. The unfinished floor is the base layer (e.g. the concrete slab), whereas the finished floor is the floor build-up and covering on top of this base. The build-up of the floor depends on the usage of the respective building. For residential buildings a soundproof and heat-insulated floor build-up is a good solution. Requirements:
EnEV: U-value = 0.50 W/m²K
DIN 4108: R = 0.90 m²K/W Avoid the addition of new concrete slabs in old buildings. There is the risk that water which previously could diffuse through the floor to the air is blocked and thus has to escape into the walls (rising moisture) =>bloom and moist walls. Always let a specialist check for pressurised water. Casting a new concrete floor has led to considerable moisture damages, especially where old buildings are concerned.

Build-up: Starting at the bottom 300 mm of rubble or gravel as an anti-capillary layer, 200 mm concrete slab (can be thinner), PE-film as moisture barrier, 80 mm Hiss Reet panel extra as insulation, oiled paper, 80 mm cork-clay floor screed for ground levelling and moisture control, floor battens, floor boards. Details on the Use and Application of Hiss Reet Panels as Floor Insulation:
  1. The moisture barrier should overlap by at least 20 cm at the joints.
  2. The cork-clay floor screed should be dry before the floor battens are placed.
