Sub Slab Insulation Board

Some floors have an empty space or a basement underneath. Cold air and moisture can come up through the slab. Your room feels cold and damp. Our sub slab insulation board stops this. You put it under the floor slab. It blocks cold air from below. It also blocks moisture. The room above stays warm and dry. We have made XPS since 2003.

Also, these boards are perfect for basement renovations, garage floors, and warehouse floors. They resist moisture from the ground and prevent rising damp. We have supplied them for many industrial projects. The boards do not deform under heavy forklift traffic because of their high compressive strength (up to 500 kPa on request). We also provide installation training videos. If your workers have questions, our technical team answers within 24 hours. Choose our sub slab insulation board for durable and dry concrete slabs.
