John Newton & Co. Ltd | Basement Drainage Systems
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.“
Newton® Fibran XPS 500-C boards are used to form a 50mm insulated 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.
Newton® Fibran XPS 500-C is supplied in Packs of 8 Boards.
Each Board Dimensions: (W) 600mm x (L) 1000mm x (H) 50mm - (0.6m²).
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).
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.
As the spacer below Cavity Drain Flooring Membranes.
Protection of liquid applied waterproofing membranes applied externally to retained walls.
Insulated support below Newton® 403 HydroBond waterproofing membrane.
Parking decks and green roofs.
Full external envelope insulating of subterranean structures sited permanently within the water table.
The Basedrain and Floordrain drainage channels that the Insulated Spacer is placed adjacent to, can develop a maximum of 50mm of water pressure when at full capacity. To prevent flotation of the floor the floor build must exert a force (weight) that is greater than 50mm of water pressure.
The weight is calculated by multiplying the density of the floor elements by the height of the floor elements. For example:
65 mm of Screed:Screed density is 1.7. Multiply by the thickness: 1.7 x 65 mm = 110 mm. Weight, of screed is twice the weight of the water pressure.
18 mm of T&G Chipboard:Chipboard density is 0.65. Multiply by the thickness: 0.65 x 18 mm = 11.7 mm. Weight of chipboard is not sufficient. Fibran XPS 500-C boards must be mechanically fixed.
The shrink film should be removed immediately before application of Newton® Fibran XPS 500-C.
Stagger boards and ensure that the drainage slots are lined up to allow for unhindered drainage.
Cut to size with a saw, knife or hot wire device.
The Fibran boards are mechanically fixed to the slab / raft using 90mm Insulation Fixings, 5 fixings per board, one at 100mm in from each corner and one in the centre of the board.
Sensitive to materials containing solvents.
Possible incompatibility with PVC waterproofing membranes.
