Insulation

Garage conversions will most likely 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 room. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to 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 typically accomplished by making use of 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 be installed around windows and doors as these areas can leak heat especially severely. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same level as the rest of your home. Flat roofs additionally require insulation. This is 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 added above the roof joists. Floor insulation is also required in garage conversions. This is less difficult if the floor level of the garage requires raising 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 flooring doesn’t need to be lifted it may be necessary to dig out the floor to add the required insulation.
