Dura Original is the professional choice for electric underfloor heating installations. The revolutionary system acts as two products in one. Firstly the mat is a decoupling membrane which guards against sub floor movement and stress.
Dura Original Decoupling and Underfloor Heating Cable Carrier Mat
It is of vital importance that the installation of any underfloor heating system is preplanned. Care must be taken to understand the requirements of the heating system of your choice. The heating cable layout must be pre-planned to avoid any “cross overs”. The positioning of sensors and the power supply must be predetermined.
For general room heating we recommend that cables be installed in the membrane at 75mm.
Advantages of Dura Heating Wire Carrier Matting:
DURA ORIGINAL PREPARATION
The subfloor must be free of any loose material that could impair adhesion. It must be level and able to bear weight. Any levelling must be completed before DURA Matting is installed. The adhesive should be chosen dependent on the nature of the subfloor. The adhesive must be capable of bonding to the sub floor surface and to the backing fleece of the DURA mats.
Maintaining the stud pattern alignment, the matting sections should be cut to size to cover the desired surface. If subject to heavy traffic it is recommended that they be protected from damage by over laying walk boards.
For most surfaces a water-based thin-bed adhesive (C2 quality) can be used. The adhesive is applied to the sub floor using a serrated trowel (6mm x 6mm).
In wet areas it is advised to seal junctions between mat sections with tape. Pre-formed corner sections can be used for internal and external corners.
As soon as the DURA Original matting has been installed and the adhesive has cured, the electrical heating system can installed to the manufacturer’s instructions.
Tiles can 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”.
Dura Original matting is not suitable for external use.
Where movement joints are required, follow professional guide lines – BS 5385. TTA Guidelines or contact our technical team.
NOTES
When used with 2mm cable it is advisable to incorporate a 3 stud locking loop every 30cm. This ensures the cable is retained under tension.
Dura Original is supplied in rolls of 5m, 10m, and 15m rolls. The nominal width of these is 1m.
Due to unavoidable trimming of the material to ensure the production pattern is maintained the width may be reduced by up to 25mm.
Suitable for heating cables of 2mm - 5.5mm
