Insulation

Garage conversions usually necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently has to adhere to building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, 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 installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally performed by employing internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must also be installed around doors and windows as these areas can leak heat especially poorly. 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 achieved 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 elevating 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 elevated it may be necessary to dig out the floor to add the necessary insulation.
