Insulation

Garage conversions often require additional insulation as the garage space will be converted into a habitable room, and consequently needs to comply with 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 roofs. To meet building regulations the garage conversion must meet the U-values in all of these areas, but additional insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically done by using 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 be installed around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same level as the rest of your house. Flat roofs also require insulation. This is performed using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other option is a warm roof, where insulation is added above the roof joists. Floor insulation is also needed in garage conversions. This is less difficult if the floor level of the garage requires lifting in order to meet the rest of the home as another 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 required insulation.
