Insulation

Garage conversions will often necessitate additional insulation as the garage space will be changed into a habitable room, and therefore has to adhere to building regulations for insulation in this kind of space. These regulations designate a U-value for insulation, which gauges 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 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 prevent heat from dissipating through the walls. Insulation must also be added around windows and doors as these areas can leak heat particularly badly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same standard as the rest of the property. Flat roofs also require insulation. This is done 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 installed 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 the floor does not need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
