Insulation

Garage conversions will often require supplementary insulation as the garage space will be changed into a habitable room, and consequently must adhere to building regulations for insulation in this type of space. These regulations specify a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of these areas, but additional insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally done 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 installed around doors and windows as these areas can leak heat particularly badly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same level 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 needed 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 additional 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 elevated it may be necessary to dig out the floor to add the necessary insulation.
