The increased stress within the installation caused by thermal movement can cause problems to the installer. Separation or Isolation Membranes are ideal for removing shear stress from tiled installations. This removes a major obstacle to fixer confidence in installing these systems.

 

By absorbing this stress the membrane allows the tiled surface to remain intact. The air spaces under the membrane have two benefits, they allow residual moisture to gradually escape therefore helping to prevent cracks forming in the substrate. The air spaces also allow the heat to be spread evenly across the floor surface making the heating action more general and effective.

 

CI matting requires no special precautions when used within a heated installation.

 

The only requirement is the selection of an adhesive suitable for use with the substrate. This adhesive must be capable of bonding to the substrate and achieving a mechanical fix with the fleece on the underside of CI matting.

 

The electrical heating elements should be installed underneath the CI matting following the manufacturer’ instructions. Standard thin set adhesive can be used to fix tiles in place.  A modified flexible grout should be used to complete the installation.
