Insulation

Garage conversions will often need supplementary insulation as the garage space will be altered to a habitable room, and consequently must adhere to 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 adhere to building regulations the garage conversion must meet the U-values in all of these areas, but additional insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally performed 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 installed around doors and windows as these areas can leak heat especially severely. 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 is done 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 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 extra layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
