    Waterproofing a New-Build Basement and Swimming Pool, West Sussex

  • Newton Fibran XPS 500-C is a 50mm deep, closed-cell thermal insulation board made from rigid extruded polystyrene foam (XPS). The product is manufactured in accordance with EN 13164 – “Thermal insulation products for buildings – Factory made products of extruded polystyrene (XPS)-specification.” 

    Produced exclusively for Newton Waterproofing Ltd, Newton Fibran XPS 500-C insulation boards are used to form a 50mm spacer adjacent to the Basedrain and Floordrain drainage channels within the Newton System 500 cavity drain waterproofing system. The insulation boards are rated at 500 kPa and feature specifically designed slots to the underside of the boards, that in combination with the perimeter and spine drainage channels of Newton System 500 form a fully drained supporting spacer below the floor drainage membrane.

    The insulation boards can also be used as a protection for Newton liquid applied waterproofing membranes applied externally to new earth retained structures or retained walls, uniquely offering protection, insulation and drainage within one product.
