Insulation

Garage conversions usually necessitate extra insulation as the garage space will be converted into a habitable room, and consequently has to comply with building regulations for insulation in this kind of room. These regulations designate a U-value for insulation, which measures 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 of the areas, but extra insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically accomplished by employing 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 installed around doors and windows as these areas can leak heat particularly badly. 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 using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other possibility is a warm roof, where insulation is installed above the roof joists. Floor insulation is also needed in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the home as an extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If flooring does not need to be raised it may be necessary to dig out the floor to add the required insulation.
