XPS 400 Dry Underfloor Heating Boards Made from Floor Plans (D16 / D20)
We offer XPS 400 dry underfloor heating boards, manufactured individually according to your room floor plans or underfloor heating project. This is a reliable solution when you need fast installation, low system weight, high thermal insulation, and accurate project execution.
Boards are manufactured for underfloor heating pipes:
✅ D16
✅ D20
Based on your drawings, we design and manufacture a complete system including:
• XPS 400 boards with pre-cut/milled pipe channels
• pipe routing between rooms
• door and wall crossings
• manifold connections
• numbered boards for fast and easy installation
Result: you receive a fully prepared dry underfloor heating system — all you need to do is install it.
Why choose XPS 400 boards made according to your project?
This solution is beneficial for installers, designers, and private customers.
⏱️ Saves installation time
Boards are manufactured exactly according to your floor plans, therefore during installation:
• no additional measurements or pipe routing corrections are needed on-site
• door/wall crossings are already planned
• manifold connections are prepared in advance
• the risk of errors is significantly reduced
✅ Installation becomes faster, easier, and more accurate.
🎯 100% project execution
If you have an underfloor heating design/project — it will be implemented fully: pipe spacing, loops, zones, manifold connections, and transitions between rooms.
✅ No compromises or adjustments during installation.
🧩 Optimized pipe routing and a clean system layout
During the design phase we ensure:
• optimal loop lengths
• even heat distribution
• neat manifold connections
• convenient door and wall crossings
XPS 400 Board Thickness Options
We manufacture XPS 400 boards in the following thicknesses:
✅ 30 mm
✅ 40 mm
✅ 50 mm
Thicker XPS boards provide better thermal insulation and are especially useful when you want to reduce heat loss downward.
Where is XPS 400 dry underfloor heating suitable?
✅ Renovation projects (when screed/concrete is not possible)
✅ Timber floors and lightweight constructions
✅ Modular cabins / modular homes
✅ Timber frame houses
✅ Attics
✅ When low weight and fast installation are important
✅ When you need better thermal insulation under the heating system

FAQ – Frequently Asked Questions
1) What drawings do I need to provide?
We accept floor plans in PDF or DWG format. If you don’t have a project, a clear drawing or photo with dimensions, door openings and manifold location is also suitable.
2) Can you manufacture according to an underfloor heating project?
Yes. If you have a heating project, the system will be manufactured exactly according to the project, including pipe spacing, loops, zones and manifold connections.
3) Will I need to modify the boards on-site?
Usually — no. The boards are produced according to your drawings and numbered, so installation is fast and accurate without any on-site adjustments.
4) Which pipe diameters are supported?
Boards can be manufactured for underfloor heating pipes D16 or D20.
5) Are door and wall crossings included?
Yes. During design we include door and wall crossings, as well as transitions between rooms.
6) Are manifold connections included?
Yes. Based on the manifold location, we design and produce manifold connections so that installation is straightforward and requires no improvisation on-site.
7) Which XPS 400 thickness should I choose – 30, 40 or 50 mm?
• 30 mm – when you need a lower system height
• 40 mm – the most universal option for most projects
• 50 mm – for maximum insulation and reduced heat loss downward
8) Is XPS 400 suitable for renovation?
Yes. It is one of the best solutions for renovation and lightweight constructions because the system is light, fast to install, and provides excellent thermal insulation.
