Description

Impact reducing sound insulation, supplied in rolls composed of granulated extra resilient EPDM rubber bonded to a tough, non-woven waterproof backing.  G8 is a specifically formulated resilient insulation designed to specifically comply with the requirements of the Approved Document E.  In particular with regard to the following:

 

Maximum dynamic stiffness - Minimum thickness under loading

Weighted reduction in impact sound pressure level (∆Lw) of not less than 29dB

Applications

Impact reducing sound insulation for separating floors.  Designed for use beneath sand/cement screeds on concrete floors.

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.
