Newton® 603 Flooring Membrane (3mm Stud)

Newton® 603 Flooring Membrane (3mm Stud)

John Newton & Co. Ltd | Damp Proofing

Damp Proofing Membranes Flooring Membranes Newton 603

Newton® 603 is a high quality flooring membrane suitable for use above new and existing floors. The 3mm studs allow for pressure equalisation of dampness within the floor below, allowing for dissipation at the room perimeter and subsequent drying of the floor.

The studs also give slight compression to footfall, making the floor very responsive, comfortable and ideal as the floor membrane for performance sports floors.

Newton® 603 Membrane uncouples the floor finish from the substrate so that movement is not transferred to the floor finish above.

This Newton Membrane also bridges small cracks, allowing for quick floor installation above less than ideal substrate.

This Newton® Membrane is guaranteed against deterioration for 30 years, and has a life expectancy of at least 50 years (DIN 9001:2000) and is inert with high compressive loading stability. It is highly resistant to water, alkalies, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and other small organisms.

Newton® Membranes can be finished over with screed, 18mm or 22mm T&G chipboard or partical board. Laminate and timber flooring should be installed over a layer of 18mm or 22mm T&G chipboard

Available in Roll sizes ranging from 20M² to 40M².
