Insulation

Garage conversions often require extra insulation as the garage space will be changed into a habitable room, and therefore needs to 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, floors, and roofing. To comply with building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be installed to exceed 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 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 standard as the rest of your home. Flat roofs additionally require insulation. This can be done utilizing a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also essential 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 raised it might be necessary to dig out the floor to add the required insulation.
