Insulation

Garage conversions will most likely need extra insulation as the garage space will be changed into a habitable room, and therefore needs to adhere to building regulations for insulation in this kind of space. These regulations specify a U-value for insulation, which measures 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 three of the areas, but supplementary insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed 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 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 standard as the rest of your house. Flat roofs additionally require insulation. This can be 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 required in garage conversions. This is easier if the floor level of the garage requires lifting 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 does not need to be elevated it might be necessary to dig out the floor to add the necessary insulation.
