Insulation

Garage conversions often need additional insulation as the garage space will be altered to a habitable room, and therefore has to 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 the areas, but supplementary insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by employing 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 added 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 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 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 raising in order to meet the rest of the house as an extra 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 elevated it could be necessary to dig out the floor to add the required insulation.
