Insulation

Garage conversions often necessitate extra insulation as the garage space will be converted into a habitable room, and therefore needs to comply with building regulations for insulation in this kind of room. These regulations designate a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary 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 prevent heat from dissipating through the walls. Insulation must be added around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same standard as the rest of your home. Flat roofs also require insulation. This can be performed 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 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 another layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
