Insulation

Garage conversions will most likely 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 space. These regulations set a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofs. To meet building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be added to exceed these values and improve 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 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 the property. Flat roofs additionally require insulation. This is performed by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also required in garage conversions. This is easier if the floor level of the garage requires lifting in order to meet the rest of the house as an extra layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it might be necessary to dig out the floor to add the necessary insulation.
