1.2.1 WALLS, CEILING AND FLOOR INSULATION
Choice of insulation panels
The manufacturers recommend the following
insulation panels:
• Single layer insulation panels
• “Complex” insulation: insulation is covered with a cladding material (plaster, mineral, etc.),
• Sandwich: insulation is covered on each side with a wooden panel or plaster board.
Important:
Coverings protect the insulation from impact and guarantees its longevity. Avoid using
mineral- fibre insulation panels (glass wool, rock wool, etc.) as they can absorb moisture and lose their
insulation qualities.
Floor insulation
The cellar floor must be able to support the racks and the wine stored. Insulation must therefore be chosen with a
sufficient compressive resistance.
Reduce the risk of damage from punctures (i.e. from wine racks or shelving legs) by using the following:
• “Complex” insulation panels, covering their top side with a sufficiently resistant panel.
• Covering the insulation with a chipboard panel (thickness around 15 mm), or any other appropriate covering
(e.g. screed and slab).
1.2.2 DOORS
These form part of the insulation continuity. There are two possible solutions:
• Glazed doors: double-glazing or even triple-glazing
must
be used with a good UG coefficient (max. 1.2 W/…….)
• If solid doors are used, they should be insulated in the same way as the other walls.

DID YOU KNOW?
Some insulating materials are damaged by rodents (mice, rats, etc.). You should therefore check that the cellar
walls have no gaps or cracks through which rodents can reach the insulation. If necessary, cover the
insulation on the inside of the cellar with a protective liner.
Polyurethane as an insulating material, due to its chemical composition, will not be damaged by rodents.
