Insulation

Garage conversions typically 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 type of space. These regulations specify a U-value for insulation, which measures 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 additional insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally accomplished by employing 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 added around doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of the property. Flat roofs also 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 essential in garage conversions. This is less difficult if the floor level of the garage requires raising in order to meet the rest of the home as an extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
