Insulation

Garage conversions frequently require additional insulation as the garage space will be altered to a habitable room, and therefore must adhere to building regulations for insulation in this kind of room. 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 of these areas, but supplementary insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally performed 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 windows and doors as these areas can leak heat especially severely. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This is done using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also required 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 another 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.
