Can you advise me on damp proofing and underfloor heating insulation?
Hello Craig
You certainly have quite a lot going on there. We would suggest seeking the services of a building professional with respect to the damp problem, they will be much better placed to offer specific advice following a detailed survey of the damp issues.
Generally, time served building contractors will have heating engineers on their payroll who will be able to offer advice on current insulation requirements with respect to your under floor heating project.
If you would like any advice on the installation of the tiles or the ancillary products once you are ready to start tiling, please feel free to contact us, we'll be happy to help.
