Insulation

Garage conversions frequently necessitate supplementary insulation as the garage space will be changed into a habitable room, and therefore must adhere to building regulations for insulation in this type of space. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofing. To meet building regulations the garage conversion must meet the U-values in all of the areas, but extra insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically done 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 be installed around windows and doors as these areas can leak heat particularly badly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same standard as the rest of your house. 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 essential 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 another layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it could be necessary to dig out the floor to add the necessary insulation.
