• Integrated stud structure securely accommodates Schluter DITRA-HEAT-E-HK electric radiant heating cables, ensuring even heat distribution across floors.
  
• ncoupling layer neutralizes substrate movement to prevent tile and grout cracking in residential and commercial high-traffic areas.
• Waterproof and vapor management system protects moisture-sensitive substrates while allowing vapor escape to prevent mold growth.
• Immediate walkability after installation, enhancing jobsite efficiency and reducing labor downtime.
• Compatible with diverse substrates, including concrete, gypsum, plywood, OSB, and existing flooring.
• Eliminates the need for self-leveling compounds, with cables embedded directly into membrane channels.
• Suitable for vinyl, WPC, LVT, LVP, SPC, laminate, and tile installations, ensuring versatile project applications.
• Covered by Schluter’s system warranty when installed with approved cables, thermostats, mortars, and accessories.
• No thin-set required to install membrane means a faster and easier installation.
• The membrane can easily be repositioned until pressure is exerted.
• Less mess, less cleanup, and fewer tools required.
• The stud structure of DITRA-HEAT-PS is specifically designed to allow for the easy installation of DITRA-HEAT-HK heating cables.
• Nominal 1/4" (5.5 mm) thickness minimizes tile assembly thickness and reduces transitions to lower surface coverings.
• Self-leveling compounds are not required to encapsulate the cables into the membrane.

Product Description:

The Schluter®-DITRA-HEAT-PS Peel and Stick Membrane simplifies radiant floor heating installation for residential and commercial spaces using an advanced pressure-sensitive adhesive (PSA) backing. This peel-and-stick system bonds directly to clean, load-bearing substrates, eliminating thin-set mortar and reducing installation mess while speeding up project timelines.

This uncoupling membrane features an integrated studded structure that securely holds DITRA-HEAT-E-HK heating cables, providing customizable, energy-efficient underfloor heating with even heat distribution beneath tile, stone, LVT, vinyl plank, and laminate. The membrane’s low-profile 5.5 mm thickness minimizes floor buildup, allowing flush transitions to other surfaces for seamless room designs.

Functioning as a crack-isolation system, DITRA-HEAT-PS neutralizes substrate movement to prevent cracked grout and tiles while maintaining surface stability under heavy loads in high-traffic residential and light commercial environments, including bathrooms, kitchens, laundry rooms, basements, offices, and hospitality spaces.

Waterproofing and vapor management are integrated into the system to protect moisture-sensitive substrates. Vapor channels allow excess moisture to escape, reducing the risk of mold and substrate deterioration in wet environments. For ANSI A118.10 waterproofing, the system can be paired with Schluter KERDI products for showers and spa applications. Compatible with thin-set mortars and multiple floor finishes, DITRA-HEAT-PS provides a reliable underlayment for radiant heating systems while improving energy efficiency as a primary or secondary heat source. The system pairs seamlessly with Schluter thermostats in 120V and 240V configurations to optimize heat control, comfort, and energy consumption.

This innovative underfloor heating membrane system embodies German engineering efficiency, combining underfloor heating, uncoupling, waterproofing, vapor management, and crack prevention into a single product that is easy to install for professionals and homeowners. Whether used in a full bathroom renovation, kitchen remodel, or a commercial project, DITRA-HEAT-PS delivers long-lasting performance, consistent warmth, and peace of mind backed by Schluter’s system warranty.

For those seeking the benefits of both Ditra Heat and uncoupling membranes, the DHPS512M is a great option. This model combines the uncoupling properties of the Ditra matting with the electric floor heating functionality. The DHPS512M provides a sturdy and reliable foundation for tile installation while allowing for the incorporation of the Ditra Heat cables. The DHPS512MDITRA-HEAT-PS is a peel-and-stick membrane that features a pressure-sensitive adhesive to bond the membrane to the substrate, eliminating the need for thin-set mortar.

Quick and easy to install, DHPS512M integrates customizable, comfortable electric floor warming with the same functions associated with DITRA-HEAT: uncoupling, waterproofing*, vapor management, and load support to ensure a long-lasting tile installation. Simply remove the transparent release film from the fleece side of the membrane to expose the layer of adhesive, and embed it into the substrate. Schluter-DITRA-HEAT-PS is a peel and stick membrane that features a pressure-sensitive adhesive (PSA) to bond the membrane to the substrate, eliminating the need for thin-set mortar. Quick and easy to install, DITRA-HEAT-PS integrates customizable, comfortable electric radiant floor heating system warming with the same functions associated with DITRA-HEAT: uncoupling, waterproofing, vapor management, and load support to ensure a long-lasting tile installation.

DITRA-HEAT-PS is suitable for applications with engineered wood (plywood), vinyl, wood plastic composite (WPC), luxury vinyl tiles (LVT), luxury vinyl planks (LVP), stone plastic composite (SPC) tiles and planks, and laminate flooring. See the Alternate Floor Coverings over DITRA-HEAT Technical Bulletin for more information, including requirements and limitations. Please note that all substrates must be entirely clean, even, and load bearing. Bond inhibiting surfaces (residue) must be removed prior to the application of DITRA-HEAT-PS. Note: Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application. Minimum tile format is 2" x 2" (5 cm x 5 cm).
