Insulation

Garage conversions frequently need supplementary 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 set a U-value for insulation, which measures 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 extra insulation can be installed to exceed 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 pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be installed around windows and doors as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same level as the rest of your home. Flat roofs also require insulation. This can be performed by 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 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 extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be lifted it could be necessary to dig out the floor to add the required insulation.
