Insulation

Garage conversions usually need extra insulation as the garage space will be converted into a habitable room, and therefore needs to comply with building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, floors, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of the areas, but supplementary insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically performed by making use of 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 also be added around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same standard as the rest of your house. Flat roofs additionally require insulation. This can be achieved 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 needed 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 lifted 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.
