The table below ( choice of insulation ) can be used to determine the type and the thickness of insulation
needed according to the internal volume of the cellar and a cellar temperature of 12°C.
Insulation continuity :
Insulating components must be assembled preferably by interlocking panels or glueing the panels
together, to ensure perfect continuity of insulation.
This is very important: it prevents heat and humidity entering from the outside which would counter the
effects of regulation.
The validity of the WINEMASTER guarantee depends on the values in the "Choice of insulation" table
being strictly respected, for all the cellar walls, including floor and ceiling + door, as well as perfect
continuity of insulation.

1.2.2 INSULATING WALLS AND CEILING
The manufacturers propose their insulating panels in several forms:
- insulation alone
- complexes: the insulation is lined with a facing (plaster, mineral...)
- sandwiches: the insulation is lined on each side with a wooden or plaster panel.
The panel facing is important: it protects the insulation from shocks and guarantees long life.
Do not use mineral fibre insulation (Glasswool, stonewool) because it stores humidity !
