Insulation

Garage conversions typically require extra insulation as the garage space will be converted into a habitable room, and therefore has to adhere to building regulations for insulation in this type of space. These regulations designate a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, and roofing. To meet building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically 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 windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same level as the rest of your house. Flat roofs also require insulation. This is achieved 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 easier if the floor level of the garage requires elevating in order to meet the rest of the home as another layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it might be necessary to dig out the floor to add the necessary insulation.
