Insulation

Garage conversions frequently need extra insulation as the garage space will be converted into a habitable room, and consequently has to comply with 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 of the areas, but supplementary insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by using 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 be added around doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same standard as the rest of your home. Flat roofs additionally 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 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 elevating in order to meet the rest of the home as another layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be raised it may be necessary to dig out the floor to add the required insulation.
