Insulation

Garage conversions typically need supplementary insulation as the garage space will be altered to a habitable room, and therefore needs to comply with building regulations for insulation in this type of room. 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 comply with building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by employing internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must also be installed around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same standard as the rest of the property. 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 required in garage conversions. This is easier if the floor level of the garage requires lifting in order to meet the rest of the home as an additional layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If flooring does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
