Insulation

Garage conversions often need additional insulation as the garage space will be changed into a habitable room, and therefore has to adhere to building regulations for insulation in this kind of room. 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 adhere to building regulations the garage conversion must meet the U-values in all of these areas, but extra insulation can be installed to exceed these values and increase 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 also be added around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same standard as the rest of your home. Flat roofs also require insulation. This is done by 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 installed above the roof joists. Floor insulation is also required in garage conversions. This is less difficult if the floor level of the garage requires raising 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 doesn’t need to be lifted it could be necessary to dig out the floor to add the necessary insulation.
