Insulation

Garage conversions will often 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 kind of space. These regulations specify 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 three of these areas, but additional insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally accomplished by making use of internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must be installed around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same standard as the rest of your home. Flat roofs also require insulation. This is performed utilizing 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 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 additional layer of insulation can be easily put into either a lifted concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
