Insulation

Garage conversions frequently necessitate extra insulation as the garage space will be altered to a habitable room, and consequently has to adhere to building regulations for insulation in this kind of space. These regulations specify a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all three of these areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by using internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must be installed around doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard 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 option is a warm roof, where insulation is installed above the roof joists. Floor insulation is also required in garage conversions. This is easier if the floor level of the garage requires lifting in order to meet the rest of the home as another layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If flooring does not need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
