Easy to Install Minimal build height—3mm thick Suitable under ceramic, porcelain & natural stone tiles Document E Compliant 18dB Impact Sound Improvement without covering Good Thermal Properties Suitable for Refurbishment & New Build

A resilient layer made of waste rubber and cork mixed with a polymer binder which is suitable for use under most floor finishes such as ceramic, porcelain and natural stone tiles and soft floor coverings such as vinyl, wood and carpet. The matting has been developed for use in both commercial and residential buildings such as apartments, hotels, hospitals etc. The product has been developed to meet the current Building Regulations and is Document E compliant. The matting also has exceptionally good insulating qualities. Resistance to the Passage of Sound (Part E) Effective from July 1st 2004 Part E was introduced to deal with the problem of noise and to improve the resistance of structures to the passage of transmitted sound. Insulation standards are specified for walls and floors: a minimum of 45dB for airborne sound and a maximum of 62dB for impact sound on floors

Fixing Norcros Acoustic Matting With a suitable vinyl trowel, apply Norcros Acoustic Adhesive to the substrate and push the acoustic matting firmly into the adhesive. Allow to dry.

ACOUSTIC MATTING

Fixing Tiles Prime the Acoustic matting with undiluted Norcros Prime Bond and allow to dry. Tiles should be fixed using Norcros Thick Bed Stone & Porcelain Adhesive. Only mix enough adhesive that can be used within 20 minutes. Apply the adhesive to the floor using an appropriate notched floor trowel. Push the tiles into the adhesive ribs with a firm twisting action and check by lifting a tile that the adhesive is in total con-tact with the floor and that void free solid bed fixing is achieved. Apply in temperatures above 5oC. When used in high temperatures a shortened application time will result. Once the adhesive has dried, (generally after 3 hours at 20oC) tiles may be grouted using either Norcros 4 into 1 or Norcros Flexible Floor & Wall Grout. Movement Joints Movement joints should be provided as specified in British Standard BS 5385: Part 3.
