Insulation

Garage conversions typically necessitate additional insulation as the garage space will be altered to a habitable room, and therefore must comply with building regulations for insulation in this type 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 the areas, but additional insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally accomplished by making use of 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 doors and windows as these areas can leak heat especially severely. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same standard as the rest of your house. Flat roofs additionally require insulation. This is performed using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent 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 lifting in order to meet the rest of the house as an extra layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it may be necessary to dig out the floor to add the required insulation.
