Insulation

Garage conversions often necessitate additional insulation as the garage space will be changed into a habitable room, and consequently needs to comply with building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofing. To comply with building regulations the garage conversion must meet the U-values in all of the areas, but supplementary insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed 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 be installed around windows and doors as these areas can leak heat especially poorly. 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 additionally 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 added above the roof joists. Floor insulation is also essential 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 the floor doesn’t need to be elevated it could be necessary to dig out the floor to add the necessary insulation.
