Can this be done?.We are having an extension built to extend our kitchen dining area.It will have a large traditional style rooflight and have brick walls with french windows at one end.I don;t think it will be subject to extreme heat variations.I have given up on the idea of tiling and underfloor heating as this form of warming often seems to break down.However i need something warm underfoot as i have 4 young kids and this room will be used all year round.Has anyone had any experience in doing something similar?.
