3 - CELLAR INSULATION

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 e￿cient product on the market. It is the least ￿ammable andthe most durable material. It also has the advantage of not being attacked by rodents. Furthermore, extruded polystyrene boards can be layered andtherefore prevent thermal bridges. To increase your conditioner’s lifespan and reduce electricity consumption, we recommend that you use extruded polystyren 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).

Insulation boards: di￿erent methods of ￿tting are possible

How can you determine whether or not a material is a good insulator? The insulation performance of a material is establishedybits R thermal resistance (m2.°C/W). It determines the material’s ability to conduct heat.

R = e/ λ - The greater the R coe￿cient, the better the insulation. (λ = thermal conductivity coe￿cient)

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 ￿tting are possible:

•Against the walls

-Standard extruded polystyrene board: pre-cut to the dimensions of the area to be conditioned, they are ￿tted using high-bondortarm . For a more acceptable ￿nish, it is possible to ￿x 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 ￿nishes 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 roomotbe 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 pressuwater 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 polystyren.

•On the floor (insulation optional)

-Original clay ￿oor: not insulating favours the passage of humidity, which is good for the wine.

-Concrete ￿oor (for example): Concrete is a very poor insulator. A few centimetres of ￿ne gravel can, in some cases, improve insulation.

It is essential that the surface material used for the ￿oor (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,recisionp knife...
