Insulation

Garage conversions usually need extra insulation as the garage space will be converted into a habitable room, and consequently must adhere to building regulations for insulation in this kind of space. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary 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 prevent heat from dissipating through the walls. Insulation must be added around doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This is achieved by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also needed in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the house as an extra layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
