Insulation

Garage conversions typically necessitate supplementary insulation as the garage space will be converted into a habitable room, and consequently needs to adhere to building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which assesses 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 these areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically performed by using internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be installed around windows and doors as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same standard as the rest of your home. Flat roofs also require insulation. This can be achieved 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 less difficult 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 the floor doesn’t need to be lifted it might be necessary to dig out the floor to add the necessary insulation.
