Insulation

Garage conversions typically require additional insulation as the garage space will be changed into a habitable room, and therefore needs to adhere to building regulations for insulation in this type of space. These regulations set a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all of these areas, but extra insulation can be added to surpass 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 doors and windows as these areas can leak heat particularly badly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same level as the rest of the property. Flat roofs additionally require insulation. This can be done utilizing 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 required in garage conversions. This is easier if the floor level of the garage requires elevating in order to meet the rest of the house as an additional layer of insulation can be easily put into either a lifted 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.
