Insulation

Garage conversions typically need extra insulation as the garage space will be converted into a habitable room, and therefore 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, flooring, and roofs. To meet building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically done by making use of 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 added around doors and windows as these areas can leak heat especially badly. 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 also require insulation. This can be done 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 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 home as another 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 elevated it might be necessary to dig out the floor to add the required insulation.
