Insulation

Garage conversions usually need supplementary insulation as the garage space will be altered to a habitable room, and consequently has to comply with building regulations for insulation in this type of space. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all three of these areas, but extra 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 pre-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 especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same level as the rest of the property. Flat roofs also require insulation. This can be performed using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent 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 lifting in order to meet the rest of the home as an additional layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If the floor does not need to be lifted it may be necessary to dig out the floor to add the required insulation.
