Insulation

Garage conversions will most likely necessitate additional insulation as the garage space will be changed into a habitable room, and therefore must comply with 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, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but additional insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally done by employing 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 added around doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This is performed by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other option is a warm roof, where insulation is added above the roof joists. Floor insulation is also essential in garage conversions. This is less difficult if the floor level of the garage requires raising in order to meet the rest of the home as an extra layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If flooring does not need to be raised it might be necessary to dig out the floor to add the necessary insulation.
