Insulation

Garage conversions frequently require additional insulation as the garage space will be converted into a habitable room, and therefore needs to comply with building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofs. To meet building regulations the garage conversion must meet the U-values in all of the areas, but additional insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished 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 installed around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be achieved utilizing 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 added above the roof joists. Floor insulation is also required in garage conversions. This is easier if the floor level of the garage requires elevating in order to meet the rest of the house as an extra layer of insulation can be easily added to either a lifted 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 necessary insulation.
