Insulation

Garage conversions typically necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently has to adhere to building regulations for insulation in this kind of room. These regulations set a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, floors, and roofs. To comply with building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished 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 windows and doors 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 your house. Flat roofs additionally 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 option 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 lifting 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 the floor doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
