Insulation

Garage conversions will often necessitate extra insulation as the garage space will be changed into a habitable room, and therefore must comply with building regulations for insulation in this kind of room. These regulations set a U-value for insulation, which gauges 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 these areas, but extra insulation can be added to exceed 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 be added around doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same standard as the rest of your house. Flat roofs also require insulation. This can be 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 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 added to either a lifted concrete floor, timber joists or a floating floor. If flooring does not need to be lifted it may be necessary to dig out the floor to add the necessary insulation.
