Insulation

Garage conversions frequently necessitate extra insulation as the garage space will be changed into a habitable room, and therefore must adhere to building regulations for insulation in this type of space. These regulations set a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofs. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically done by making use of 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 also be installed around doors and windows as these areas can leak heat particularly 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 can be achieved 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 essential in garage conversions. This is less difficult if the floor level of the garage requires elevating in order to meet the rest of the house as an additional layer of insulation can be easily put into either a lifted concrete floor, timber joists or a floating floor. If the floor does not need to be raised it might be necessary to dig out the floor to add the required insulation.
