Insulation

Garage conversions typically necessitate extra insulation as the garage space will be altered to a habitable room, and therefore has 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, flooring, 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 exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally done by making use of 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 doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of your home. Flat roofs additionally require insulation. This is achieved using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid 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 easier if the floor level of the garage requires elevating in order to meet the rest of the house as an extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be elevated it could be necessary to dig out the floor to add the necessary insulation.
