Insulation

Garage conversions will most likely need additional insulation as the garage space will be converted into a habitable room, and therefore must adhere to building regulations for insulation in this kind of room. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all of these areas, but additional insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally done 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 installed around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same level as the rest of your house. 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 avoid condensation forming. The other option is a warm roof, where insulation is installed above the roof joists. Floor insulation is also essential 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 elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it might be necessary to dig out the floor to add the required insulation.
