In-Screed Heating Cable Under All Floor Coverings

In Screed Heating Cable can be installed under any floor. The perfect option for new build or extension projects, designed to be laid into a 50mm -100mm liquid or sand and cement screed substrate.

Easy to install and can be used in any room size or environment. To aid the efficiency of the heating, the cable should be laid directly on to a Celotex or Kingspan thermal insulation.

Alternatively, it can be laid on to our Cement Coated Tile Backer Boards, or XPS Hard Thermal Insulation Boards. The cable also comes with high adhesion fixing tape and easy to follow step by step instruction guide. This includes an equation to work out your exact wire spacing.

For peace of mind, the heating is also covered with a full 15-year manufacturers warranty. When being used as a primary heat source, it is recommended a floor coverage of at least 90% with the cable is achieved. The cable can be spaced as close as 70mm within your concrete substrate (providing approximately 260w/per sqm).

This makes the In screed cable the most powerful and responsive form of heating available under any floor.

Electric Vs Water - What is the difference?

The common misconception is that electric underfloor heating is far more expensive than it's water/gas counterparts. In truth, they are super efficient, when controlled correctly and installed on to thermal boards.

Unlike water based heating, which is predominantly regulated off an air sensor, electric heating should always be controlled off a floor sensor. This enables the heating to be far more efficient and responsive, far quicker than the more expensive and unreliable underfloor water heating.

The main benefit of underfloor heating is that there are no unsightly radiators required in most instances. Electric heating can be also used in many ways. It can used as a comfort heat source, taking the chill off the floor in the colder months, or as a primary heat, with 100% of the floor covered with the Loose wire or In screed cables.
