Insulation

Garage conversions frequently require supplementary insulation as the garage space will be altered to a habitable room, and therefore must adhere to building regulations for insulation in this kind 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 roofs. To comply with 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 accomplished by making use of 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 be added around doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of the property. Flat roofs additionally require insulation. This is 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 required in garage conversions. This is easier if the floor level of the garage requires lifting in order to meet the rest of the home as an additional layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
