Overlay House Packs are part of the Polyplumb Overlay Underfloor Heating System

Installed over the existing floor using only 18mm in depth, Overlay allows floor heating to be installed where traditional underfloor systems would either require expensive excavation or would require the floor to be raised to an unacceptable level.
Overlay is a dense fibrous panel used for heavyweight floor coverings such as ceramics and solid wood which can both be fitted and secured directly to the panels.
