Insulation

Garage conversions frequently need extra insulation as the garage space will be converted into a habitable room, and consequently has to adhere to building regulations for insulation in this type of space. These regulations set a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all of these areas, but extra insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by employing internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be installed around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same standard as the rest of the property. Flat roofs also require insulation. This can be achieved 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 required in garage conversions. This is less difficult if the floor level of the garage requires elevating in order to meet the rest of the house as an extra layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be lifted it might be necessary to dig out the floor to add the required insulation.
