A underfloor heating system with a hook-and-loop system is no longer a niche solution. More and more builders, craftsmen, and ambitious DIY enthusiasts are opting for the hook-and-loop system – because it is laid faster than classic stapler or knob systems, requires less installation height, and can adapt to almost any construction situation. But how well suited is the hook-and-loop system specifically for new builds? And what do you need to consider when working with it in old buildings or during renovations? This article gives you a clear overview – whether you want to install it yourself or, as a skilled craftsman, are making the best system choice for your project.

How does a hook-and-loop underfloor heating system work?
The principle is as simple as it is ingenious: A thin hook-and-loop fleece is unrolled on the prepared subfloor and immediately adheres to the floor thanks to a self-adhesive release liner. The heating pipe – equipped with a hook-and-loop strip – is then simply pressed onto the fleece and adheres firmly. No stapler, no fastening clips, no second person. The pipe can be removed and repositioned at any time, which offers an enormous advantage for complex room geometries or corrections during installation.
The MC KLETT system from MC Therm consists of three components: the hook-and-loop fleece (in Slim, Silent, or TempusFlat variants), the hook-and-loop heating pipe with integrated hook-and-loop strip, and optionally a suitable manifold and control technology. Everything is available as a complete set and is coordinated – a clear advantage, especially for projects without a specialist company.
Hook-and-loop underfloor heating system in new builds
In new builds, the hook-and-loop system is an excellent choice – both for single-family homes and for multi-family homes and commercial properties. Installation on a fresh concrete slab or on an insulation layer is quick and clean. Thanks to its flexible roll form, the hook-and-loop fleece adapts easily to any room size and floor plan.
MC KLETT Slim in new builds:
The 2 mm thin hook-and-loop fleece is the standard solution for new builds where no special sound insulation requirements exist. The structure consists of 2 mm fleece, the heating pipe (e.g., 16 mm), and at least 10 mm screed cover over the pipe – resulting in a total installation height of 28 mm with a 16 mm pipe. With a slimmer 14 mm pipe, the structure reduces accordingly. This can be easily integrated into standard screed planning.
MC KLETT Silent in new builds:
Those working on concrete slabs in multi-family housing or rental apartments must comply with the requirements of DIN 4109. The MC KLETT Silent achieves exactly that: 5 mm thin, certified with 28 dB impact sound insulation – and thus the only hook-and-loop system solution on the market that offers sound insulation and minimal installation height simultaneously. The structure is identical to Slim, only the fleece is 3 mm thicker: 5 mm fleece + 16 mm pipe + 10 mm screed = 31 mm total installation height. Stapler systems with comparable sound insulation values require significantly thicker insulation boards – this makes the MC KLETT Silent the most economical and fastest solution for skilled tradesmen in multi-story housing construction.
For both new build variants: Installation is possible with genuine one-person assembly. Experience shows that 20–30 m² can be laid in an hour – a value that is difficult to achieve with stapler devices.
Hook-and-loop underfloor heating in old buildings and for renovation
Perhaps the greatest advantage of a hook-and-loop underfloor heating system is evident in renovation and old buildings. Here, the available installation height is usually the decisive criterion – and it is precisely here that the hook-and-loop system scores over all classic alternatives.
The problem in old buildings:
Doors, stair landings, and connections to adjacent rooms often allow only a few centimeters of clearance. Stapler systems with insulation boards and cement screed quickly reach a total installation height of 70–90 mm – simply not feasible in many existing buildings without extensive adjustments to door frames and transitions.
The solution with MC KLETT:
The MC KLETT Slim achieves a total installation height of 28 mm with a 16 mm pipe and 10 mm screed cover – i.e., 2 mm fleece + 16 mm pipe + 10 mm screed above. With a 14 mm pipe, the structure reduces to 26 mm. It becomes even more compact with the TempusFlat Klett: This hook-and-loop fleece, specially developed for thin-layer systems, is perforated and designed for special screed – the minimum installation height here is only 17 mm including screed. This allows underfloor heating to be retrofitted even in existing buildings where no system would have worked before.
Important prerequisites for renovation: The subfloor must be clean, dry, even, and load-bearing. Unevenness over 3 mm should be leveled before installation. The hook-and-loop fleece adheres to most mineral subfloors, cement and anhydrite screed, and load-bearing old coverings – depending on the product and subfloor preparation. A pressure test of the heating circuit after installation and before pouring is always mandatory.
For DIY enthusiasts in old buildings, the hook-and-loop system is the ideal introduction to DIY underfloor heating: the tolerance for errors during installation is high, corrections are possible at any time, and the compact transport volume of the hook-and-loop fleece rolls makes material transport in old buildings with narrow staircases significantly easier than with bulky knob boards.
Which hook-and-loop system variant suits my project?
The choice of the correct hook-and-loop fleece variant depends on three factors: available installation height, sound insulation requirements, and screed type.
MC KLETT Slim (2 mm): The universal solution for new builds and renovations without special sound insulation requirements. Compatible with cement and anhydrite screed. Total installation height from 26 mm (14 mm pipe) or 28 mm (16 mm pipe) – each 2 mm fleece + pipe diameter + 10 mm screed cover.
MC KLETT Silent (5 mm, 28 dB): The choice for concrete slabs in new builds and for projects with sound insulation requirements according to DIN 4109. Also suitable for renovations. The structure follows the same logic as with Slim – only the fleece is 5 mm thick instead of 2 mm: i.e., 5 mm fleece + pipe diameter + 10 mm screed cover. With a 16 mm pipe, this results in 31 mm, with a 14 mm pipe, 29 mm total installation height.
TempusFlat Klett (thin-layer): The special solution for maximum build-up minimization in old buildings. The perforated fleece is designed for anhydrite special screed and allows total build-up heights of only 17 mm – the flattest underfloor heating in the hook-and-loop system currently available.
Conclusion: For whom is underfloor heating with a hook-and-loop system the right choice?
Underfloor heating with a hook-and-loop system is the right decision in two situations: if you want to install it yourself as a DIY enthusiast and are looking for a forgiving, tool-free system – or if you, as a specialist craftsman, want to save time and material costs and still deliver standard-compliant results.
In new buildings, the hook-and-loop system convinces with fast installation, minimal waste and – with the MC KLETT Silent – with unique sound insulation at the lowest possible build-up height. In old buildings and during renovation, it is often the only technically feasible solution without extensive structural modifications. You can learn exactly how to install underfloor heating with a hook-and-loop system in this article.
Anyone who wants to take advantage of the MC KLETT system will find the right underfloor heating hook-and-loop system on mctherm.de – including a complete set configurator, which allows the system to be adapted to your own area in just a few clicks.
