Insulation

Garage conversions often need supplementary insulation as the garage space will be changed into 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 measures the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all 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 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 added around doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of the property. 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 avoid condensation forming. The other option is a warm roof, where insulation is added above the roof joists. Floor insulation is also needed in garage conversions. This is less difficult if the floor level of the garage requires lifting in order to meet the rest of the home as an extra layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If the floor does not need to be elevated it could be necessary to dig out the floor to add the required insulation.
