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.
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 and installation in accordance to the user guide.
