Insulation

Garage conversions frequently require supplementary insulation as the garage space will be altered to a habitable room, and consequently must comply with 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, floors, and roofing. 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 surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by making use of internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must be installed around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This can be done 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 installed above the roof joists. Floor insulation is also required in garage conversions. This is less difficult if the floor level of the garage requires raising in order to meet the rest of the house as another layer of insulation can be easily put into 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 required insulation.
