Insulation

Garage conversions usually necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently needs to adhere to building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofs. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by using internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be installed around doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same level as the rest of the property. Flat roofs additionally require insulation. This is performed using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also required in garage conversions. This is easier if the floor level of the garage requires elevating in order to meet the rest of the house as an extra layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it might be necessary to dig out the floor to add the required insulation.
