Heated Floors

Tiled floors are ideal for any room in the home. But when you add warmth to your tiled floor, you add a touch of luxury that brings your flooring experience to a whole new level. Imagine bare feet walking across a nice cozy floor that also has all the benefits associated with tile. An allergen-free floor covering, tile is available in endless designs, colors, and sizes, and offers easy-maintenance too.

When properly installed, a heated tile floor is practically indestructible. To protect the integrity of your investment, tiles need to be protected from multiple angles: from underneath, at perimeters and transitions, and within large expansions.

Uncoupling

The frequent fluctuations in temperature caused by a floor warming system lead to more expansion and contraction of materials in the floor assembly. These frequent changes create greater movement stresses in the tile covering and increase the need for uncoupling. Existing installation methods require the installation of two separate systems – a floor warming system and an uncoupling system.

DITRA-HEAT is the only system that provides floor warming and uncoupling in a single layer. Uncoupling refers to the act of preventing any movement and stress that occurs in the subfloor from transferring through to the tile above, thus preventing cracked tiles and grout.

Let’s have a look at two scenarios for heated floors, both featuring the DITRA-HEAT system. Each of the two applications below is a complete DITRA-HEAT floor warming system, but cover two different flooring substrates to optimize their use: DITRA-HEAT for use on plywood or OSB substrates and DITRA-HEAT-TB for use on concrete substrates.

1. Uncoupling and waterproofing membrane: Schluter®-DITRA-HEAT

In this floor warming installation the DITRA-HEAT matting is being used because the substrate is plywood. The DITRA-HEAT has been specifically designed to allow for the DITRA-HEAT-E-HK heating cables to be snapped into place, while providing the same effective uncoupling protection as DITRA to prevent cracked tiles and grout. Made of polyethylene, DITRA-HEAT also serves as a waterproofing layer that protects moisture-sensitive substrates, such as plywood/OSB. Free-space on the underside of the matting provides a route for excess moisture and vapor to prevent damage to the tile layer above. DITRA-HEAT performs all these functions while still providing adequate support/load distribution for the tile covering.

2. Electric heating cables: Schluter®-DITRA-HEAT-E-HK

DITRA-HEAT-E-HK are heating cables that can be snapped into place, without the use of clips or fasteners. The entire tile floor can be heated, or cables can be placed to create customized heating zones. The DITRA-HEAT-EK cables are held securely within the DITRA-HEAT mat, so no self-leveling compounds are needed to encapsulate the heating cables. The installer has complete flexibility on where the cables are placed so every installation is customized to suit the exact requirements of the owner. And instead of waiting for a leveling compound to set, tile installation can begin immediately, resulting in a much faster installation.

3. Digital Thermostat: Schluter®-DITRA-HEAT-E-RT

DITRA-HEAT-E-RT is programmable touchscreen thermostat, that allows you control your electric floor warming system any way you want. The thermostat features a 5 mA built-in ground fault circuit interrupter (GFCI) with indicator light, and includes a floor temperature sensor.

1. Uncoupling and waterproofing membrane with integrated thermal break: Schluter®-DITRA-HEAT-TB

In this floor warming installation the DITRA-HEAT-TB matting with its integrated thermal break is being used because the substrate is concrete. This system has been designed to allow for the DITRA-HEAT-E-HK heating cables to be snapped into place, and provide the same effective uncoupling protection as DITRA to prevent cracked tiles and grout. The integrated thermal break directs heat up into the tile rather than down into the subfloor, resulting in tiled floors that warm up to 70% faster over concrete substrates. By preventing the loss of heat to the subfloor, DITRA-HEAT-TB provides considerable energy savings and complete comfort even with tiled floors that are traditionally cold when installed over concrete. Free-space on the underside of the matting provides a route for excess moisture and vapor to prevent damage to the tile layer above. DITRA-HEAT-TB performs all these functions while still providing adequate support/load distribution for the tile covering.

Movement Joints

Movement joints are an integral part of any tile assembly. The various components of a tile assembly (tile, mortar, substrate, etc.) expand and contract according to each component’s intrinsic physical properties with changes in moisture, temperature, and loading, resulting in internal stresses. Schluter®-Systems’ prefabricated movement joint profiles protect tile edges and prevent sound bridges and surface water penetration, resulting in a permanent, maintenance-free installation.

Transition Profiles

Because ceramic and stone tiles are inherently brittle, their exposed edges can chip and crack if left unprotected. Transitions between floor surfaces and at thresholds are particularly vulnerable to damage. Schluter®-Profiles provide edge protection and transitioning at thresholds and between adjacent surfaces, resulting in durable, maintenance-free tiled coverings.
