The dry floor polystyrene board with aluminum reflectors provides both thermal and sound insulation functions.
The dry heating system is a universal and optimal heating solution for floor and wall surfaces, suitable for both new and existing buildings. It is especially ideal for renovations and frame houses, where concrete pouring options are limited or not possible at all.
The boards include specially shaped grooves for the installation of aluminum plates for pipe mounting. The aluminum reflectors cover almost the entire surface of the panel, ensuring even heat distribution without any losses.
Quick Installation Guide: Dry Underfloor Heating System (EPS/XPS)
1. Subfloor Preparation
- Panels are laid on a flat, clean, and dry surface (concrete, OSB, tiles, wood).
- If needed, fix panels using PVA glue (for wood) or solvent-free MS polymer adhesives (for concrete or tiles).
2. Heating Panel Installation
- EPS or XPS panels with pre-cut pipe grooves and aluminum reflector foil.
- Pipes are inserted into grooves; foil is cut in turning zones.
- Panels can be glued or laid loosely (if the top layer evenly distributes the load).
3. Top Layer/Baseboard (if needed)
- For glued floorings or heavy loads, install:
- Knauf Brio, Cetris, Georas TE boards or
- Self-leveling compound (e.g., Weberfloor 4310).
- When gluing onto foil – use primer compatible with metal surfaces (e.g., Mapei Eco Prim Grip).

Flooring Type
|
Installation Conditions
|
|
Laminate
|
With underlay, directly on panels (from 300 kPa).
|
|
Parquet
|
Directly on panels if the load is light. Use additional base if heavy furniture.
|
|
Vinyl
|
Only on XPS400 (≥400 kPa). On lower strength panels – a support layer is needed.
|
|
Tiles
|
Directly (with primer) or on Cetris / Knauf Brio boards.

📌 About Panel Strength:
- XPS300 (300 kPa): suitable for laminate, floating parquet.
Not recommended for vinyl or tiles without a support layer.
- XPS400 (400 kPa): high-strength panels – allow direct installation of vinyl or tiles, if surface is flat and stable.
🛠 When in doubt – use a load-distribution base. It will ensure long-term durability and protect the heating system.
