Insulation

Garage conversions will often need supplementary insulation as the garage space will be converted into a habitable room, and consequently must adhere to building regulations for insulation in this kind of space. These regulations specify a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally accomplished 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 be added around doors and windows as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be done by 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 installed above the roof joists. Floor insulation is also essential in garage conversions. This is easier if the floor level of the garage requires raising 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 doesn’t need to be raised it could be necessary to dig out the floor to add the necessary insulation.
