Insulation

Garage conversions frequently necessitate supplementary insulation as the garage space will be altered to a habitable room, and therefore has to adhere to building regulations for insulation in this kind 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 meet building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished 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 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 demand insulation to the same standard as the rest of the property. Flat roofs additionally require insulation. This is performed 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 added above the roof joists. Floor insulation is also essential 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 put into either a raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it might be necessary to dig out the floor to add the necessary insulation.
