Insulation

Garage conversions usually require extra insulation as the garage space will be converted into a habitable room, and therefore must adhere to building regulations for insulation in this type of space. These regulations designate a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofs. 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 surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally accomplished 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 also require insulation. Pitched roofs need insulation to the same level as the rest of the property. Flat roofs also require insulation. This is done 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 installed above the roof joists. Floor insulation is also required 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 doesn’t need to be lifted it could be necessary to dig out the floor to add the necessary insulation.
