Insulation

Garage conversions will most likely necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently must adhere to building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, and roofs. To comply with building regulations the garage conversion must meet the U-values in all three of the areas, but additional insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically done by employing 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 windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same standard as the rest of the property. Flat roofs additionally require insulation. This is achieved by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other possibility is a warm roof, where insulation is installed 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 an additional layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor doesn’t need to be elevated it may be necessary to dig out the floor to add the required insulation.
