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, etc...)
- 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,etc...) 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.

T
he 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 and installation in accordance to the user guide.
