Pro-mat Pro-mat decoupling membrane for electric underfloor heating – 1, 5 and 10 m²

Pro-mat decoupling membrane for electric underfloor heating

The Pro-mat decoupling membrane is designed for the easy and even installation of a loose electric heating cable beneath a tiled floor. The studs hold the cable securely in position and allow the cable spacing and heat output per square metre to be adjusted.

The membrane also creates a decoupling layer between the subfloor and tiled surface. This helps reduce the direct transfer of stress and minor movement from the subfloor to the tiles.

Available sizes

• 1 m² sheet: suitable for small rooms and additional sections.
• 5 m² roll: practical for medium-sized floor areas.
• 10 m² roll: suitable for larger rooms and projects.

Choose the required heat output

The studs have a spacing of 30 mm. When used with the Pro-mat heating cable rated at 13.78 W per metre, the heat output can be adjusted by installing the cable closer together or further apart.

• Two-stud spacing, approximately 60 mm: around 230 W/m².
• Three-stud spacing, approximately 90 mm: around 150 W/m².
• Four-stud spacing, approximately 120 mm: around 115 W/m².

For most applications, we recommend a three-stud spacing and a heat output of approximately 150 W/m².

Benefits of the Pro-mat decoupling membrane

• Easy and even installation of the heating cable.
• Flexible installation around drains, toilets and other obstacles.
• Choice of different cable spacings and heat outputs.
• Helps absorb stress between the subfloor and tiled surface.
• Easy to cut to the required size.
• Suitable for renovation and new-build projects.

Installation overview

1. Ensure that the subfloor is level, clean and structurally sound.
2. Cut the membrane to size and bond it using a suitable flexible tile adhesive.
3. Install the floor sensor inside a separate conduit between two cable runs.
4. Press the heating cable between the studs using the chosen spacing.
5. Measure the cable resistance before, during and after installation.
6. Fully cover the membrane and heating cable with a suitable flexible tile adhesive.
7. Install the tiled floor finish.

Important information

This product contains only the decoupling membrane. The heating cable, thermostat and floor sensor are not included and can be ordered separately or as part of a complete kit.

The heating cable must never be shortened, extended, crossed or laid over itself. The electrical connection should be installed or checked by a qualified professional.
