Insulation

Garage conversions frequently necessitate additional insulation as the garage space will be converted into a habitable room, and consequently needs to adhere to building regulations for insulation in this kind of room. These regulations specify a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all of the areas, but additional insulation can be added to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed 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 particularly severely. 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 additionally require insulation. This is performed utilizing 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 required in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the house as another layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
