Insulation

Garage conversions often require additional insulation as the garage space will be converted into a habitable room, and therefore must comply with building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished by making use of 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 added around windows and doors as these areas can leak heat particularly badly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This can be performed 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 installed above the roof joists. Floor insulation is also required in garage conversions. This is easier 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 elevated concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it could be necessary to dig out the floor to add the required insulation.
