Insulation

Garage conversions will often require supplementary insulation as the garage space will be changed into a habitable room, and consequently needs to adhere to building regulations for insulation in this kind of space. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of these areas, but extra insulation can be added 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 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 need insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be performed 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 less difficult if the floor level of the garage requires elevating in order to meet the rest of the home as another layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If the floor does not need to be raised it could be necessary to dig out the floor to add the necessary insulation.
