Insulation

Garage conversions usually need extra 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 set a U-value for insulation, which assesses 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 three of these areas, but extra insulation can be added to surpass 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 existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must be added around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same standard as the rest of your house. Flat roofs also require insulation. This can be achieved by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is installed above the roof joists. Floor insulation is also needed in garage conversions. This is less difficult if the floor level of the garage requires raising in order to meet the rest of the home as an extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it might be necessary to dig out the floor to add the required insulation.
