How many BEFIRO underfloor heating boards do I need?
One BEFIRO XPS underfloor heating board measures 1250 × 600 mm, giving a coverage area of 0.75 m² per board.
1,25 m × 0,60 m = 0,75 m²
How Many Boards Do You Need for 100 m²?
100 m² ÷ 0,75 m² = 133,33 boards.
Round this figure up to 134 boards before accounting for cutting waste. The actual quantity required depends on the room dimensions, layout and the number of cuts needed around windows, balconies, doorways and other obstacles.
During installation, boards often need to be cut around walls, alcoves, columns and service penetrations. For this reason, it is generally advisable to order additional boards. A 5–10% allowance is a practical starting point, depending on the shape and layout of the installation area.
| Floor area | Quantity of boards |
|---|---|
| 100 m², without extra allowance | 134 |
| 100 m² + 5% allowance | 141 |
| 100 m² + 10% allowance | 148 |
How Much Extra Should You Allow for Your Project?
- 5% extra – generally suitable for simple, regularly shaped rooms with minimal cutting.
- 10% extra – a safer allowance for houses with multiple rooms, alcoves and more complex layouts.
For a typical 100 m² house, ordering approximately 140–145 boards may be sufficient, depending on the floor plan. For a more complex layout, consider ordering up to 148 boards.
Tip: Before ordering, calculate the total area to be covered and consider the layout of each room separately. This will help you estimate cutting waste more accurately and reduce the risk of running short during installation.
