Product Summary
Today's Schluter Systems installation systems allow the incorporation of ceramic and stone tile on virtually any surface. In addition to traditional projects such as bathrooms and kitchens, popular tile applications now include countertops, exterior balconies, and even bedrooms.
Schluter-KERDI is a bonded waterproof membrane with limited crack-bridging capabilities. It is made of soft polyethylene, which is covered on both sides with a special fleece webbing to anchor the membrane in the thin-set mortar.
Schluter-DITRA is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration, and an anchoring fleece laminated to its underside.
Construction and Materials
Schluter Systems offers a range of innovative solutions designed to enhance the installation and longevity of tile. While a specific product name isn't provided, based on the category of "Tile - Floor/Wall (Underlayment)" and the brand name, the following description outlines the typical construction and materials associated with Schluter Systems' underlayment products, drawing from general knowledge of their offerings.
Schluter Systems' underlayment products are engineered to provide a stable, waterproof, and insulating layer beneath tile installations. These systems are crucial for preventing common issues such as cracked tiles, moisture damage, and uncomfortably cold floors.
Construction and Materials
Schluter underlayment membranes are typically constructed from a closed-cell foam core, often polyethylene or a similar closed-cell foam material. This core provides several key benefits:
- Waterproofing: The closed-cell nature of the foam inherently resists water penetration, creating a reliable barrier against moisture from the substrate or from spills on the tile surface.
- Crack Isolation: The foam's flexibility allows it to absorb movement and stress between the substrate and the tile. This prevents minor structural shifts or drying shrinkage in the subfloor from transferring to the tile assembly, thus preventing cracks.
- Thermal Insulation: The foam core offers thermal breaks, reducing heat transfer. This results in more comfortable floor temperatures, especially in conjunction with radiant heating systems.
- Sound Deadening: The foam can also contribute to reducing impact sound transmission, offering a quieter environment.
The foam core is typically laminated on both sides with a special anchoring fleece or reinforcing fabric. This fleece serves multiple purposes:
- Mechanical Bonding: The fleece provides a textured surface that allows for excellent mechanical bonding with thin-set mortar. This ensures a secure connection between the underlayment and both the subfloor and the tile adhesive.
- Reinforcement: The fleece adds tensile strength to the membrane, further enhancing its crack-isolation capabilities and overall structural integrity.
Schluter Systems often incorporates integrated sealing features within their underlayment systems. This may include:
- Sealing Tapes: Specific sealing tapes are designed to overlap and bond with the underlayment membranes at seams, corners, and penetrations, creating a seamless waterproof envelope.
- Preformed Corners and Sealing Elements: For critical areas like corners and changes in plane, Schluter offers preformed pieces that integrate seamlessly with the underlayment and sealing tapes, ensuring complete waterproofing.
The overall design of Schluter underlayment products aims for ease of installation while delivering robust performance. The materials are lightweight and can be cut to size easily with standard tools. The anchoring fleece allows for direct application of thin-set mortar, eliminating the need for separate bonding agents in many cases.

- Benefit: Prevents tile and grout cracking caused by substrate movement and moisture.
- Benefit: Functions as a waterproofing layer in wet areas.
- Benefit: Simplifies installation and provides a stable substrate for tiling.
- Schluter-DITRA-HEAT: Integrates heating cables within the uncoupling membrane for warm floors.
- Benefit: Provides customizable comfort heating for tiled floors.
- Benefit: Offers the same uncoupling and waterproofing benefits as DITRA.
Waterproofing Membranes
For critical wet areas like showers and bathrooms, Schluter offers robust waterproofing solutions.

Options-Styles
Schluter Systems offers a range of underlayment products designed to provide a reliable and waterproof foundation for tile installations. These systems are engineered to address common challenges in tiling, such as moisture management, crack isolation, and thermal breaks, ensuring the longevity and performance of the finished tile floor or wall.
The core of Schluter's underlayment offering revolves around their innovative uncoupling membranes. These membranes are specifically designed to absorb the stresses that can occur between the substrate and the tile assembly. Movement within the building structure, such as expansion and contraction due to temperature changes or minor settling, can cause cracks in tile and grout. Schluter's uncoupling membranes, such as SCHLUTER-DITRA, are engineered with a grid-like structure of cavities that allow for independent movement of the tile covering from the substrate. This effectively prevents stress from transferring to the tile and grout, thus preventing cracks.
Beyond uncoupling, these underlayments provide crucial waterproofing and vapor management. The integrated waterproofing membrane within systems like DITRA acts as a continuous barrier, preventing moisture from reaching the substrate below. This is particularly vital in wet areas like bathrooms and showers, protecting the building structure from water damage. The vapor management aspect is also important; DITRA, for example, allows moisture vapor to escape from the substrate through its air channels, mitigating the risk of moisture buildup and related issues.
Schluter's underlayment solutions also offer thermal break capabilities. When installed over concrete slabs that are subject to significant temperature fluctuations, the uncoupling membrane can help reduce the transfer of heat or cold. This can contribute to a more comfortable living environment and may even lead to energy savings.
The product line includes various options tailored to specific project needs:
* **SCHLUTER-DITRA:** This is the flagship uncoupling membrane, providing uncoupling, waterproofing, and vapor management. It is suitable for a wide range of applications, including floors and walls in residential and commercial settings. DITRA is typically made of a special plastic material and is designed to be bonded directly to the substrate with thin-set mortar.
* **SCHLUTER-DITRA-HEAT:** This system builds upon the functionality of DITRA by integrating heating cables directly into the membrane. This allows for the creation of heated floors and walls, providing comfort and warmth. DITRA-HEAT provides the same uncoupling, waterproofing, and vapor management benefits as DITRA, with the added advantage of radiant heating.
* **SCHLUTER-KERDI:** While primarily known as a waterproofing membrane, KERDI can also be used in conjunction with other Schluter products or as a standalone waterproofing solution for wet areas. It is a sheet waterproofing membrane made of soft polyethylene, specifically designed for waterproofing walls and floors in wet areas.
* **SCHLUTER-BEProfessional:** This is a drain board system designed for showers and wet rooms. It combines drainage, waterproofing, and support for tile installations, creating a cohesive and reliable shower base.
The installation of these underlayment systems is designed to be straightforward, typically involving bonding the membrane to the substrate using thin-set mortar and then tiling directly over the membrane. Specific installation details and product recommendations are available for each system to ensure optimal performance.
