CDM Fibran XPS-500C

Multi-Functional Insulation: CDM Fibran XPS-500C provides thermal insulation, drainage, and protection within one product, making it ideal for various waterproofing applications.
Certified Environmental Impact: With an Environmental Product Declaration (EPD) certified to ISO 14025, the product’s lifecycle environmental impact is transparently reported, showcasing its sustainability.
High Compression Strength: Rated at 500 kPa, these boards offer robust support and stability, ensuring reliable performance in demanding conditions.
Integration with Newton CDM System: Specifically designed to work within the Newton CDM System, the slotted insulation boards enhance the effectiveness of BaseDrain and FloorDrain channels, ensuring optimal drainage and support.
Versatile Protection: Suitable for use as protection for liquid-applied waterproofing membranes on new earth-retained structures or retained walls, providing comprehensive insulation and drainage solutions.

Newton CDM Fibran XPS-500C 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.”

CDM Fibran XPS-500C has been certified to ISO 14025 standard with an Environmental Product Declaration (EPD). This reports the full value chain from material extraction to the manufacturing of the product, usage and end of life, declaring the products environmental impact from a lifecycle perspective.

Produced exclusively for Newton Waterproofing Ltd, CDM Fibran XPS-500C insulation boards are used to form a 50mm spacer adjacent to the CDM BaseDrain and CDM FloorDrain drainage channels within the Newton CDM System 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 the Newton CDM System 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.
