Insulation

Garage conversions frequently need extra insulation as the garage space will be converted into a habitable room, and consequently must comply with building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically 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 also be installed around doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same level as the rest of your home. Flat roofs additionally require insulation. This can be performed by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also essential 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 an extra layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it could be necessary to dig out the floor to add the required insulation.
