Insulation

Garage conversions typically require additional insulation as the garage space will be changed into a habitable room, and therefore has to 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, flooring, and roofs. To comply with building regulations the garage conversion must meet the U-values in all of the areas, but supplementary insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally done by employing internal wall insulation, which adds insulated plasterboard to the pre-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 badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of your house. Flat roofs additionally require insulation. This is 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 less difficult 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 raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
