Newton Fibran XPS-500C is a 50mm deep, closed-cell thermal insulation board made from rigid extruded polystyrene foam (XPS). They are used to form a 50mm spacer adjacent to the BaseDrain and FloorDrain drainage channels within the Newton CDM cavity drain waterproofing system.

Fibran 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 product is manufactured in accordance with EN 13164 – “Thermal insulation products for buildings – Factory made products of extruded polystyrene (XPS)-specification.”

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.

• Excellent thermal insulation characteristics with a very low coefficient of thermal conductivity

• Closed cell structure with no connecting capillaries resulting in extremely high resistance to water absorption and diffusion of water vapour

• Capable of permanent submersion in water

• Fully inert when subjected to climatic variations

• High mechanical and compressive strength and high dimensional stability

• Contains no CFC or HCFC’s

• Life expectancy is equivalent to the building in which it is installed (estimated 50 years)

• 100% recyclable

• Easy to transport, cut and apply

• Completely rot proof and does not develop any mould or other efflorescence

• No nutritional value for rodents, insects, etc

• Good resistance to acids, alkalines, aggressive ground containments and inorganic gases

Typical Applications

• As the spacer below Newton cavity drain waterproofing floor membranes

• Protection of Newton liquid applied waterproofing membranes applied externally to retained walls.

• Insulated support below HydroBond 403 Plus

• Parking decks and green roofs

• Full external envelope insulating of subterranean structures sited permanently within the water table

Suitable Substrate

• Compacted, clean, and level surfaces

• Basement concrete floor slabs and rafts

• Earth retained walls of concrete, mortar or ICF

• Compacted blinding
