Insulation

Garage conversions typically require additional insulation as the garage space will be altered to a habitable room, and consequently needs to comply with building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which measures 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 extra insulation can be added 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 stop heat from dissipating through the walls. Insulation must be installed around windows and doors as these areas can leak heat especially severely. Roofs for garage conversions will additionally 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 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 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 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 doesn’t need to be lifted it may be necessary to dig out the floor to add the necessary insulation.
