Insulation

Garage conversions frequently necessitate supplementary insulation as the garage space will be altered to a habitable room, and therefore 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 roofs. To meet building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be installed to surpass these values and increase 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 also be added around windows and doors 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 the property. Flat roofs also require insulation. This is performed 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 home as an additional layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be lifted it might be necessary to dig out the floor to add the required insulation.
