Insulation

Garage conversions frequently require extra insulation as the garage space will be altered to a habitable room, and consequently has to adhere to building regulations for insulation in this kind of space. These regulations designate a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, and roofs. To adhere to 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 improve energy efficiency. Wall insulation for garage conversions is typically accomplished by using 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 windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same standard as the rest of the property. Flat roofs also require insulation. This can be achieved utilizing 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 installed above the roof joists. Floor insulation is also needed 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 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 could be necessary to dig out the floor to add the required insulation.
