Isocheck Impact Mat 300

INSTALLATION
Prior to installation of the system, the following considerations and preparations must be taken:
  • the products should be fixed between the carpet or timber floor and sub-floor,
  • the sub-floor must be dry, clean and smooth,
  • any floor coverings must be removed,
  • all timber floorboards must be securely fixed and evened,
  • concrete floor must be free of any gaps or holes which can be properly filed with some type mortar or silicone sealant,
  • any doors opened into the room must be removed.

The mat is rolled directly onto the sub-floor surface, so that it covers the entire area and turned or butted up at all perimeter walls. If the mat is installed on top of the finished floor, the skirting must be removed and replaced, while when installed on top of a carpet, the mat should go all the way through to the gripper rail edge.

The mat should be bonded to the sub-floor surface by using the adequate adhesive, while the adjoining edges should be butted to the walls with building tape. The mat must be properly protected from any type of potential mechanical damage whereas timber and vinyl coverings and carpets can be laid directly on the mat, but solid timber flooring should be pinned to min 12mm plywood.

CERTIFICATION

The product is in compliance with Approved Document E of the Building Regulations.
