20mm Tekwarm Foiled 400 KPA UFH Board | 1200mm x 600mm | 200mm Centres for 12mm Pipe

It suits 12mm pipe systems where the rooms are well-insulated and don't need tight pipe spacing to reach target temperatures. Pipes at 200mm apart means less pipe per m², which cuts material costs on larger floors. If your system uses 16mm pipe, there's a 200mm version for that too (BM01926). And if the room's heat demand is higher, the 12mm/150mm version (BM00053) is the safer call.

Yes. 1200mm x 600mm x 20mm, 0.72 m² per board, 400 kPa EPS core with a foil face. The board itself is identical across the range. What changes is the groove: cut at 200mm centres for 12mm pipe, so you're laying significantly less pipe per m² compared to the 150mm version. An overlay is required before the floor finish.

Large solid ground floors in well-insulated new builds where 12mm pipe is already the system choice throughout. Open-plan living areas, kitchen-diners, and extensions where the room holds heat well and doesn't need to work hard to stay warm. On a big floor, 200mm spacing saves a meaningful amount of pipe and can free up manifold ports. A heat loss calculation will confirm whether 200mm is sufficient for the rooms you're heating.

If the heat loss calc says 200mm is enough, use it. You'll save on pipe and installation cost. The 150mm version (BM00053) is the right move if you haven't got a heat loss calculation, or the room has high ceilings, lots of glazing, or older construction. Honestly, 200mm works well on large well-insulated modern floors and starts to struggle everywhere else. If you're on the fence, go 150mm.
