Underground Piping

The flexible and economical MAXX-R Pipe Insulation System is a revolution in underground pipe insulation for wood burning outdoor boilers and furnaces. Until now dealers, contractors and homeowners have had to choose between cheap, poorly designed “home-made” insulation and expensive, hard-to-handle, metric sized, prefabricated pipe-in-pipe systems.

MAXX-R, a system that gives you the performance you need, the price you can afford... And it’s easy to install!
