Insulation

Garage conversions often necessitate additional insulation as the garage space will be altered to a habitable room, and therefore must adhere to building regulations for insulation in this type of room. These regulations set a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all of the areas, but additional insulation can be added to exceed these values and increase energy efficiency. Wall insulation for garage conversions is normally done by employing internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must be added around doors and windows as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same standard as the rest of the property. Flat roofs also require insulation. This can be performed 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 needed 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 extra layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be lifted it could be necessary to dig out the floor to add the necessary insulation.
