Insulation

Garage conversions will often necessitate extra insulation as the garage space will be altered to a habitable room, and therefore must adhere to building regulations for insulation in this type of room. These regulations set a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all of these areas, but additional insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by using 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 also be added around doors and windows as these areas can leak heat especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same standard as the rest of the property. Flat roofs additionally require insulation. This can be done by 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 installed above the roof joists. Floor insulation is also essential 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 an extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be elevated it could be necessary to dig out the floor to add the required insulation.
