Insulation

Garage conversions will most likely need additional insulation as the garage space will be altered to a habitable room, and consequently needs to adhere to building regulations for insulation in this type of space. These regulations set a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, 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 added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally performed by making use of 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 also be installed around doors and windows as these areas can leak heat especially severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of your home. Flat roofs additionally require insulation. This is done utilizing 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 installed above the roof joists. Floor insulation is also required in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the home as an additional layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be raised it could be necessary to dig out the floor to add the necessary insulation.
