Traditional building materials such as stone, concrete and brick are very poor insulators and only underground sections represent any real insulation.
It is therefore essential, in the majority of cases, to insulate the entire room to be conditioned.
Insulate – yes but how?
We recommend that you use extruded polystyrene, currently the most efficient product on the market. It is the least flammable and the most durable
material. It also has the advantage of not being attacked by rodents. Furthermore, extruded polystyrene boards can be layered and therefore prevent thermal
bridges. To increase your conditioner's lifespan and reduce electricity consumption, we recommend that you use extruded polystyrene which is at least 80
mm thick.
80 mm of extruded polystyrene provides the same amount of insulation as a 5m thick stone wall.
The insulation must be completely continuous (no gaps).
To allow air to be renewed in your cellar, it is recommended that you create an opening (of approximately 3 x 10 cm) at the top of the room and leave a 2
cm air gap under the door. As in natural cellars, this "breather effect" will ensure a constant and gradual renewal of air.
Insulation boards: different methods of fitting are possible
How can you determine whether or not a material is a good insulator? The insulation performance of a material is established by its R thermal resistance
(m2.°C/W). It determines the material's ability to conduct heat.
R = e/λ - The greater the R coefficient, the better the insulation. (λ = thermal conductivity coefficient)
There are 3 types of insulation boards:
Insulator only, complex (with plaster cover) or sandwich (plaster both sides)
Depending on the type of insulator chosen, several methods of fitting are possible:
• Against the walls
- Standard extruded polystyrene board: pre-cut to the dimensions of the area to be conditioned, they are fitted using high-bond mortar. For a more acceptable
finish, it is possible to fix rails onto which you screw the plaster board panels over the polystyrene.
- Sandwich or complex boards: the polystyrene is already integrated into the plaster board.
Whatever the method used, all kinds of decorative finishes are possible to obtain an attractive wall.
If you only want to condition a section of your room, install a plaster board dividing wall then insulate the side of the room to be conditioned.
N.B.: Before being insulated, walls must be clean. If they are too damp, clean them with a wire brush then clean with a high pressure water jet and paint with
an emulsion paint.
• On the ceiling and door
The process for insulating the ceiling and door is identical to that of the walls.We recommend that you use extruded polystyrene.
• On the floor (insulation optional)
- Original clay floor: not insulating favours the passage of humidity, which is good for the wine.
- Concrete floor (for example): Concrete is a very poor insulator. A few centimetres of fine gravel can, in some cases, improve insulation.
It is essential that the surface material used for the floor (whether or not covering
insulation) can support the weight of wine racks and has resistance to compression.
Tools required
- handsaw, tape measure, bricklayer's ruler, trestles, screwdriver or screw gun, drill, hammer, level, plumb line, wood mallet, spatula, precision knife...
