Insulation

Garage conversions will most likely need additional insulation as the garage space will be converted 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 assesses 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 of the areas, but additional insulation can be added to surpass these values and increase 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 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 need insulation to the same standard as the rest of your home. Flat roofs additionally require insulation. This can be achieved by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other option is a warm roof, where insulation is added above the roof joists. Floor insulation is also required in garage conversions. This is less difficult if the floor level of the garage requires lifting in order to meet the rest of the home as an additional layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If the floor doesn’t need to be elevated it could be necessary to dig out the floor to add the required insulation.
