INSULATION IN A COOLING ROOM: The recommended insulation is minimum 10-15 cm A mats. The vapour barrier shall always be on the warm side of the insulation. You can use plastic film with a thickness of 0.15-0.25 mm as vapour barrier (overlap and tape over all joints). Avoid the use of impermeable materials inside the cooling room. The recommended type of wood inside the cooling room is spruce (e.g. pine panelling can transfer flavour to food). If smooth materials are required for cleaning (e.g. bathroom panels, the panelling must be assembled so that there is a space of approx. 3 cm between the panel and the builder’s paper/insulation with an aperture at the top and bottom to allow ventilation). Builder's paper is used to keep the insulation in place and to prevent any odours. The insulation is fitted to the studding before fitting the internal panelling. If you would prefer timber/panels with surface treatment inside your cooling room, the recommended surface treatment is with a permeable, water-based paint. FLOORS IN A COOLING ROOM: It is common to lay Styrofoam under a concrete floor, but to maintain this as a floor in a cooling room, 3 cm thick Styrofoam must be laid up to the surface of the floor and directly below the area where the ground beam is laid in order to prevent a thermal bridge. If this has not been installed, the floor has to be insulated as normal. FACING THE OUTER WALL: A cold attic or cold basement (falls below +0°C in the winter) must be ventilated using 5 cm thick blocks. The plastic is fitted to the blocks before the studding. Ventilation is provided by means of apertures in the moulding or 3-4 cm drill holes at the top and bottom in to the air duct. This ensures temperatures above +0°C around the cooling room all year round, and prevents problems with rot caused by condensation in the walls, ceiling or floor. The most common size of cooling room for normal families is 2-7 m3. COOLING ROOM DOORS: Integrated doors are often used when the cooling room is installed in a kitchen. The door has a frame and you can fit it with a kitchen front to match the rest of your kitchen. External cooling room doors are a slightly less expensive alternative. They come with plastic mouldings and steel features in the door aperture. They can also be supplied in glass. Our cooling room doors can be custom made to order if you need slightly different dimensions. COOLING UNITS: Thermocold cooling units are very compact and quiet. They do not require space outside the cooling room as they are fitted inside the cooling room. Air supply to and from the unit is through valves or a duct. The only maintenance required is to clean a dust filter that is easy to access in the front of the unit inside the cooling room. A split unit is also recommended in areas that are sensitive to sound or heat. With a split unit, the compressor part is normally placed in a laundry room or cellar/technical room at a maximum distance of 10 metres from the cooling room. Please read the instructions for assembly of cooling units. STORAGE: Thermocold cooling rooms guarantee correct temperature and air humidity. Normally, temperatures will be approx. 4-5°C, but the temperature in the ambient air will vary e.g. between 2.5 to 7°C. It is therefore important to measure temperature using a thermometer placed in a glass of water. LIGHTS IN THE COOLING ROOM: TC cooling units have a connection for lights that are fitted in the cooling room ceiling. Power supply is provided via a quick-release coupling plugged directly into the cooling unit. The bulbs and lights are supplied as a complete set. We have lights that trigger from the door switch and with motion sensors. WINE CELLAR AND COOLING ROOM COMBINED: By dividing a cooling room into two parts separated by a 5-cm insulated wall and with an adjustable louvre grill at the top and bottom, you can have a cooling room on one side with a temperature of 5°C and a wine cellar on the other side with temperatures of 12-13°C. You can therefore have a practical cooling room and cold storage room using the same cooling unit.
