Insulation

Garage conversions will often require extra 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 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 extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically done 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 added around windows and doors as these areas can leak heat especially severely. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be done utilizing a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent 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 lifting in order to meet the rest of the home as another layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If the floor does not need to be lifted it may be necessary to dig out the floor to add the required insulation.
