Insulation

Garage conversions usually necessitate additional insulation as the garage space will be altered to a habitable room, and therefore has to adhere to building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which measures 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 the areas, but additional insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically performed by making use of 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 also be installed around doors and windows 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 also require insulation. This can be done by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid 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 lifting in order to meet the rest of the home as another 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 could be necessary to dig out the floor to add the necessary insulation.
