Insulation

Garage conversions often necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently needs to adhere to building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally done by using 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 be installed 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 level as the rest of the property. Flat roofs also 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 installed 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 house as an additional 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 elevated it may be necessary to dig out the floor to add the necessary insulation.
