Insulation

Garage conversions usually require additional 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 measures the rate of heat loss. These are set differently for walls, flooring, and roofing. To meet building regulations the garage conversion must meet the U-values in all three of the areas, but additional insulation can be added to exceed these values and increase energy efficiency. Wall insulation for garage conversions is normally done by making use of internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must also be installed around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of the property. Flat roofs additionally require insulation. This is done 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 installed above the roof joists. Floor insulation is also essential 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 put into 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.
