De-Coupling membrane
DHQ – Decoupling + UFHHQ 2mm Loose wire = A perfect installation.
Decoupling membrane protects tiled floors from cracking. We are now stocking and distributing the
CI-FH membrane to be used with our extensive range of loose cable systems. This membrane is the
only one to accommodate our HQ 2mm superior wire.
When is this product required?
If installing tiles on a wooden sub-floor it is recommended that a de-coupling membrane is installed.
Wooden sub-floors can have excessive movement that can cause cracking to the tiles. Fitting this
membrane stops cracking and is also a very quick way of installing our loose wire system.
How to install
1. Make sure the sub-floor is free of any loose material that could impair adhesion. It must be
level and able to bear weight. Any levelling must be completed before its
installed. The adhesive should be chosen dependent on the nature of the sub floor. The
adhesive must be capable of bonding to the sub floor surface and to the backing fleece of
the mat
2. For most surfaces use a water-based thin bed adhesive (C2 quality). The adhesive is applied
to the sub floor using a serrated trowel (6 x 6 mm) and the matting bedded into it.
3. As soon as the matting has been installed and the adhesive has cured, the
electrical heating system can be installed at 75mm Spacing.

1050 Watt 5.25 to 7.0m2 200 to 150 Watt
1500 Watt 7.5 to 10m2 200 to 150 Watt
5. Tiles can then be installed using a thin bed adhesive appropriate to the flooring.
Practically, it is advisable to apply adhesive in one operation, embedding the heating cables in that
process. Install the tiles after pre “buttering” the underside. The tiles must be embedded in
the adhesive to achieve solid bedding. The depth of the serrations on the trowel must be
appropriate to the tile format. Make sure this is all done while the adhesive is still fresh and
within its “open time”.
