Insulation

Garage conversions will most likely necessitate supplementary insulation as the garage space will be converted into a habitable room, and therefore 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 roofs. To adhere to building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is normally performed by employing 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 added around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of your home. Flat roofs additionally require insulation. This can be performed 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 raising in order to meet the rest of the house as another 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 lifted it may be necessary to dig out the floor to add the required insulation.
