Insulation

Garage conversions often necessitate extra insulation as the garage space will be converted into a habitable room, and consequently has to adhere to building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofs. 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 normally done 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 also be added around doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same level as the rest of the property. Flat roofs additionally require insulation. This can be 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 installed above the roof joists. Floor insulation is also essential 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 put into either a elevated concrete floor, timber joists or a floating floor. If the floor doesn’t need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
