Insulation

Garage conversions often necessitate supplementary insulation as the garage space will be converted into a habitable room, and consequently must adhere to building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which measures 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 these areas, but additional insulation can be installed to surpass 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 pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must be added around doors and windows as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of the property. Flat roofs also require insulation. This is 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 added 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 another layer of insulation can be easily added to either a lifted 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 necessary insulation.
