Packing & Storing
Pallet dimension 1.05 X 1.05M
Number of rolls per pallet: 40

Each pallet is wrapped in polythene pallet wrap. Although the wrapping is waterproof, inside storage is recommended to reduce the possibility of water ingress through the joints of the packaging.

Installation Instructions

The rolls should be laid parallel to each other with the joints overlapped by 4cm. The rubber should be underneath with the backing fabric on top. The insulation must be lapped up the walls by approximately 20cm to contain the screed. Any surplus can be trimmed down to finished floor level once the screed has cured. See link to Application Instructions below.

Health and Safety

This is not a dangerous material and so is not subject to the European directive 67/648/CEE. This product does not contain any hazardous component such as formaldehyde, carbide fluorine, mercury or any other similar elements and does not generate toxic fumes or smoke.
