Insulation

Garage conversions often need extra insulation as the garage space will be altered to a habitable room, and consequently has to comply with building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which gauges 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 of the areas, but extra insulation can be installed to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished by employing internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must also be added around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of the property. Flat roofs additionally require insulation. This can be achieved by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other option 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 an extra layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If the floor doesn’t need to be lifted it could be necessary to dig out the floor to add the required insulation.
