Insulation

Garage conversions will often require supplementary insulation as the garage space will be converted into a habitable room, and consequently has to comply with building regulations for insulation in this type of room. These regulations designate 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 of the areas, but extra insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally accomplished 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 be added around windows and doors as these areas can leak heat particularly badly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same standard as the rest of your home. Flat roofs additionally require insulation. This can be achieved by 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 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 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 may be necessary to dig out the floor to add the necessary insulation.
