I'm planning to do some renovations this summer and will be installing underfloor heating. We have received a material specification from LK, which includes LK's floor chipboards. But if I choose Byggelit's floor chipboards below, I save about 3000 SEK that could be used for other things. Do you think it's the same, or is it penny-wise and pound-foolish to choose cheaper boards? Anyone with experience with Byggelit?
