Insulation

Garage conversions frequently require additional insulation as the garage space will be changed into a habitable room, and therefore needs to adhere to building regulations for insulation in this kind of space. These regulations set 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 three of the areas, but supplementary insulation can be added to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically accomplished 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 also be installed around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be achieved by using 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 another 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 required insulation.
