Indecal's Slim 18: low-inertia radiant floor heating for smart renovations.

In modern renovations, the challenge is clear: improve energy efficiency without resorting to invasive interventions and minimizing construction time and costs. This is the context for Indecal's Slim 18, the low-thickness radiant floor system that combines quick installation, high performance, and next-generation living comfort.

Low-thickness technology for renovations without demolition

Slim 18 was designed to meet the typical needs of building renovations: the 18 mm gypsum fiberboard panel allows for installation directly over existing flooring, without the need for demolition. A 5 mm self-leveling layer completes the installation, creating a uniform surface ready for the final covering.
With an overall thickness of just 23 mm , the system integrates perfectly into existing buildings, respecting internal heights and without modifying doors, windows or architectural dimensions.

Low thermal inertia: immediate comfort and precise adjustment

The heart of Slim 18 is its low thermal inertia . Unlike traditional systems, which take hours to reach the desired temperature, Slim 18 responds quickly to control commands, allowing you to adjust comfort quickly.

This translates into intelligent heating and cooling management : the system operates only when needed, reducing consumption and increasing overall efficiency. The uniform distribution of heat eliminates cold spots and drafts, significantly improving the quality of life.

Energy efficiency and concrete advantages on construction sites

Slim 18 represents a solution that combines two key aspects of redevelopment in a single system: high energy performance and ease of installation . From a technical standpoint, the system is designed to work in synergy with low-temperature heat pumps, reducing consumption by up to 70% compared to traditional systems. The ability to operate in both heating and cooling modes ensures constant comfort throughout the year, with uniform temperature distribution that eliminates annoying cold spots or temperature changes.
These results translate into a concrete contribution to the sustainability objectives of buildings, in line with the new European directives on energy efficiency and emissions reduction.

But the benefits don't stop at the installation stage. Slim 18 is designed to simplify and speed up the construction phase , often the most critical in renovation projects. The low-thickness installation over existing floors eliminates the need for invasive demolition and waste disposal, significantly reducing costs and time. The self-leveling layer, just a few millimeters thick, quickly creates a uniform surface, ready for any type of covering—from tiles to parquet, from laminate to resin.
For the client, it means reduced downtime and a quicker return to using the spaces, while for designers and installers, it represents a guarantee of efficiency, practicality, and reliability in any building context.

Slim 18: the intelligent answer to redevelopment needs

With Slim 18, Indecal offers professionals an innovative radiant floor system , designed to successfully address the challenges of energy efficiency requalification. Efficiency, comfort, quick installation, and sustainability come together in a single system, capable of improving the value of properties and ensuring long-term well-being.
