Insulation

Garage conversions frequently need extra insulation as the garage space will be changed into a habitable room, and consequently has to adhere to building regulations for insulation in this kind of room. These regulations specify a U-value for insulation, which gauges 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 these areas, but additional insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically 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 also be added around doors and windows as these areas can leak heat particularly badly. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This is achieved 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 added 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 lifted concrete floor, timber joists or a floating floor. If flooring doesn’t need to be lifted it could be necessary to dig out the floor to add the necessary insulation.
