Insulation

Garage conversions often require extra insulation as the garage space will be converted into a habitable room, and therefore must adhere to building regulations for insulation in this kind of room. These regulations designate 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 increase 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 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 demand insulation to the same standard as the rest of the property. Flat roofs also require insulation. This can be done utilizing 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 essential in garage conversions. This is easier if the floor level of the garage requires elevating in order to meet the rest of the home as an additional layer of insulation can be easily put into either a lifted concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
