Insulation

Garage conversions frequently need supplementary insulation as the garage space will be converted into a habitable room, and therefore must adhere to building regulations for insulation in this type of space. These regulations designate a U-value for insulation, which assesses 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 three of the areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically accomplished 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 badly. 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 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 possibility 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 lifting in order to meet the rest of the home 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 lifted it may be necessary to dig out the floor to add the necessary insulation.
