Subfloor renovation with underfloor heating and decoupling UZIN Renoplan® - Efficient solutions for renovation and decoupling
Retrofitting underfloor heating systems with decoupling is often a challenge when renovating old buildings. However, this is efficiently solved with the UZIN Renoplan® system and the appropriate product combination of, for example, UZIN Multimoll Fleece and other innovative products. Discover how the UZIN Renoplan® system enables optimum integration of underfloor heating in renovations of old buildings.
HOW CAN A LEVEL LAYING SURFACE BE CREATED WITH A FLOOR HEATING SYSTEM? With UZIN Multimoll Fleece and the UZIN Renoplan® System
The renovation of old buildings with retrofitted underfloor heating requires special attention. The challenge lies in the combination of retrofitting underfloor heating and milling the screed. This is where UZIN Multimoll comes into play, as it provides the necessary decoupling between the screed and the floor covering. In combination with other UZIN products, this results in a tailor-made solution that takes into account both the decoupling and the underfloor heating.
Advantages of the system
- Decoupling the subfloor to reduce tension between the screed and floor covering
- High bond strength for long-lasting, stable connections between floor covering and subfloor
- Easy application thanks to practical handling
- Sustainable and low-emission - suitable for environmentally conscious renovation projects
- Minimal installation height - ideal for renovations where room height is a decisive factor
Over 250,000 satisfied craftsmen in more than 25 countries rely on UZIN systems

The UZIN Renoplan® system for substrate renovation with underfloor heating and decoupling: step-by-step instructions The UZIN Renoplan® system in use

Step 1: Vacuuming
Start by thoroughly cleaning the substrate. Use the VACUCLEAN 2 industrial vacuum cleaner to remove dust and create an optimum base for the primer.

Step 2: Priming
Apply UZIN PE 360 PLUS evenly to the screed. Use the codex X-Spray or a UZIN nylon plush roller for even distribution. Ensure that the primer is applied evenly over the entire surface and allow to dry for 30 - 60 minutes.

Step 3: Attach edge insulation strips
Install UZIN Edge Insulation Strips B along all rising components to avoid sound bridges and ensure effective decoupling. Ensure that the strips are cut to fit precisely and fastened carefully.

Step 4: Filling
Filling with stable filler (UZIN NC 118 or UZIN NC 182). These products ensure a smooth and stable surface. Apply the filler evenly and smooth the surface with a smoothing trowel to embed the pipes.

Step 5: Bonding the UZIN Multimoll Vlies
Cut the UZIN Multimoll Vlies to size and lay it loosely on the prepared surface. Apply the UZIN parquet adhesive (e.g. UZIN MK 92 S) to the screed with a suitable toothing and press the Vlies carefully into the adhesive bed. Then roll it in with a heavy roller (50 kg) to ensure even adhesion.

Step 6: Laying the floor covering
You can lay the parquet on the prepared surface as soon as the UZIN Multimoll Vlies has been completely laid. The screed ensures long-term and efficient heat distribution, which also forms a secure basis for the underfloor heating.
UZIN Multimoll Vlies
UZIN Multimoll Vlies is the perfect choice if you want to install a retrofitted underfloor heating system. This special Vlies carpet pad ensures stress relief between the substrate and the floor covering and prevents cracks. In addition, the UZIN Multimoll Vlies offers high bond strength, which ensures long-lasting stability and durability.

Efficient subfloor renovation with underfloor heating and decoupling
The renovation of old substrates with integrated underfloor heating and the retrofitting of underfloor heating places high demands on the selection and combination of the right products. The UZIN Renoplan® system provides you with a coordinated solution for retrofitting underfloor heating.The interplay of UZIN products - from the primer to the leveling compounds to the UZIN Multimoll Vlies - ensures a durable and reliable foundation. The system offers a low installation height, particularly during renovation, which means that the room height is maintained.
Another advantage of the UZIN Renoplan® system is the simple bonding and decoupling of the substrate. The UZIN Multimoll Vlies ensures that the screed and floor covering are decoupled, effectively preventing stresses and cracks. This allows you to efficiently retrofit underfloor heating. Rely on the UZIN Renoplan® system to optimize your renovation project.
