Insulation

Garage conversions will most likely require supplementary insulation as the garage space will be changed into a habitable room, and consequently has to comply with building regulations for insulation in this kind of space. 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 meet building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be added to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by using 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 be installed around windows and doors 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 your home. Flat roofs also require insulation. This is done 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 installed above the roof joists. Floor insulation is also required in garage conversions. This is less difficult 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 the floor doesn’t need to be elevated it could be necessary to dig out the floor to add the necessary insulation.
