Insulation

Garage conversions often require additional insulation as the garage space will be converted into a habitable room, and therefore must comply with building regulations for insulation in this type of space. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofing. To adhere to 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 making use of internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be added around doors and windows as these areas can leak heat particularly badly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same standard as the rest of your home. Flat roofs additionally require insulation. This can be done by 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 less difficult if the floor level of the garage requires lifting in order to meet the rest of the house as an additional 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 might be necessary to dig out the floor to add the necessary insulation.
