Insulation

Garage conversions typically require extra insulation as the garage space will be changed into a habitable room, and consequently must comply with building regulations for insulation in this kind of room. These regulations set a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all of these areas, but extra insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished by making use of 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 added around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same standard as the rest of your house. Flat roofs additionally require insulation. This can be achieved by 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 installed above the roof joists. Floor insulation is also essential in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the house as another layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be raised it may be necessary to dig out the floor to add the required insulation.
