Insulation

Garage conversions often require additional insulation as the garage space will be changed into a habitable room, and consequently must adhere to building regulations for insulation in this kind of space. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofing. To meet building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be added to surpass 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 also be installed around doors and windows as these areas can leak heat especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of your home. Flat roofs additionally require insulation. This can be achieved 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 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 elevating in order to meet the rest of the house as another layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be raised it might be necessary to dig out the floor to add the necessary insulation.
