Drainage board EPSEPS board with or without non-woven fabric for drainage and insulation of basement walls
For warm, cozy basements
Basements are often used for living, which demands thermal insulation and comfort. Exterior insulation is the best solution, which is why our EPS board is diffusion open to remove water and moisture. Made of EPS with first-rate thermal properties. It protects against heat, cold and moisture, which help lower heating costs. EPS is 98% air, which makes it extremely light.
Drainage board S80 with fabric
Allows interior moisture to escape and stops exterior moisture. It keeps the foundation wall dry and warm and improves the indoor climate. The board has a special seam that simplifies assembly and minimizes the risk of thermal bridges and downdraughts. The attached non-woven fabric prevents backfill from clogging the drainage grooves.
Drainage board S80/S200
Grooved EPS board that should be provided with a non-woven fabric to prevent backfill from clogging the drainage grooves. S80 is recommended for depths 0-2.5 meters and S200 below 2.5 meters.
EPS is 100% recyclable and at BEWI we collect, compress and extrude used EPS and reuse it as raw material for new EPS. It’s a closed-loop that saves natural resources, minimize waste, lowers CO2 emissions and water use.
