This is very important: it prevents heat and humidity entering from the outside which would counter the
effects of regulation.

1.2.2 WALL AND CEILING INSULATION
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 and loose its
insulation capacity.
Protection against rodents
Some insulating materials are damaged by rodents (mice, rats…). It is therefore essential to make sure
that the walls of the cellar do not contain holes which would allow rodents access to the insulation.
This insulation must be lined, on the inner surface of the cellar, with a protective facing.
Polyurethane insulation, because of its chemical composition, is not attacked by rodents.
1.2.3 FLOOR INSULATION
The cellar floor must be able to support shelves and the wine stored on them.
You should therefore choose an insulating material with adequate compression resistance for this part.
Manufacturers recommend appropriate insulation or materials designed specifically for floor insulation, in
their documentation.

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.
