Retrofitting flat underfloor heating when the installation height is limited and the construction process needs to remain predictable.
When retrofitting underfloor heating in older buildings or during renovations, the installation height is usually the decisive factor. At the same time, the demand for energy-efficient systems is increasing, often in combination with heat pumps. Therefore, low-profile floor constructions with good thermal conductivity that can be implemented quickly and easily are in demand.
Safetec decoupling membrane revolutionizes underfloor heating
Modern underfloor heating with only 10 mm thin screed
IDEAL TOP 15 is the ideal solution when a floor heating system with minimal installation height is required. This water-based system requires only 15 mm of installation height, including insulation, heat-conducting plate, and heating pipe, and forms a stable foundation for both renovation and new construction projects.
SAFETEC decoupling membrane is perfectly matched to the overall structure. It ensures decoupling, even load distribution, and optimal heat transfer. Only 10 mm of leveling compound required on top of SAFETEC.
This results in a total construction thickness of 25 mm including thermal insulation. The system combination is ideally suited for those seeking a low-profile underfloor heating system with short installation times, clean interfaces, and complete freedom from floor coverings.

IDEAL TOP 15 plus SAFETEC,
only 25 mm overall structure
The IDEAL TOP 15 underfloor heating system is the ideal solution when every millimeter counts, with a total installation height of just 15 mm, including insulation, heat-conducting plate, and heating pipe. The TOP 15 elements adhere to the IDEAL system technology, featuring insulation plus fixed aluminum heat-conducting plates, high heat output, and a practical pipe spacing of 150 mm.
The SAFETEC decoupling membrane complements the structure; the membrane is particularly thin, ensures optimal heat transfer, and allows for minimal installation heights. It is ideal for small, irregularly shaped areas such as hallways. For larger areas, SAFETEC can also be combined with pumpable leveling compounds for faster installation.

Thin screed is groundbreaking! Take advantage of this progress!
Why use outdated methods when SAFETEC and IDEAL TOP 15 offer a better solution?
SAFETEC is designed as a decoupling membrane for thin layers and is suitable for all common floor coverings, including mega-format tiles, parquet, and vinyl. The surface is smooth and designed for direct installation of the coverings.
The system offers clear advantages in the construction process. The surface is walkable after a short time and ready for covering in a short period. Simultaneously, a defined handover between trades is created; the heating contractor hands over a prepared surface to the flooring or tiling contractor.

Questions & Answers
Plan with good information
Here you will find answers to frequently asked questions about retrofitting flat underfloor heating systems with IDEAL TOP 15 and SAFETEC . This information will support you in planning, execution, and the safe coordination of the various trades involved.
IDEAL TOP 15 and SAFETEC products are sourced through selected specialist and distribution partners. As an OEM manufacturer, we assist with product classification and can connect you with the appropriate contact person for your project.
With IDEAL TOP 15 as a dry system and SAFETEC as a decoupling membrane, a total construction thickness of just 25 mm possible. Only 10 mm of leveling compound is required on top of SAFETEC. This is a clear advantage when door connections and transitions offer little margin for error.
Both are true in practice. IDEAL TOP 15 is a dry-construction underfloor heating system. SAFETEC applies a thin layer of leveling compound on top, ensuring a smooth, ready-to-cover surface. This allows for clean planning and reliable installation by all trades.
SAFETEC is designed for all floor coverings , including mega-format tiles, parquet and vinyl; even designer floor coverings are supported. This provides planning certainty for floor covering approval and reduces the need for special constructions.
Clear timeframes are defined for the construction process: walkable after 6 hours , for covering after 24 hours . This facilitates the scheduling of subsequent trades. In practice, the usual boundary conditions apply, such as material system, temperature, and site climate.
The SAFETEC layer forms a defined, smooth surface. This allows the heating engineer to hand over a perfectly prepared surface, while flooring and tiling installers have a clean base. This reduces coordination loops and rework.
Yes. SAFETEC is also very well suited for use in small and awkwardly shaped areas such as hallways. The membrane can be cut to size and flexibly adapted to the geometry of the space. This makes the system suitable not only for large, continuous areas, but also for renovation projects with many transitions, doorways, and changes of direction.
Yes, SAFETEC can be combined with pumpable leveling compounds. This is relevant when area coverage and speed of installation are paramount.
Yes. There is an assembly video for the SAFETEC system. The video shows the setup and the sequence of individual steps and provides support for planning, instruction, and coordination on the construction site.
