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.

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 !
IMPORTANT
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 c door, as well as perfect
continuity of insulation.
