Insulation

Garage conversions usually need extra insulation as the garage space will be altered to 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 adhere to building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally done by using 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 installed around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same standard as the rest of the property. Flat roofs also require insulation. This is achieved by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other option is a warm roof, where insulation is installed above the roof joists. Floor insulation is also required in garage conversions. This is less difficult if the floor level of the garage requires lifting 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 the floor does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
