Insulation

Garage conversions usually need additional insulation as the garage space will be altered to a habitable room, and consequently needs to comply with building regulations for insulation in this kind of space. These regulations specify a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofs. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but extra insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically accomplished by employing internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be added around doors and windows as these areas can leak heat particularly badly. 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 done utilizing 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 added to either a elevated concrete floor, timber joists or a floating floor. If the floor does not need to be elevated it might be necessary to dig out the floor to add the necessary insulation.
