Insulation

Garage conversions typically need extra insulation as the garage space will be changed into a habitable room, and consequently needs to adhere to building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to 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 normally done by employing internal wall insulation, which adds insulated plasterboard to the 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 particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of your house. 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 option is a warm roof, where insulation is installed above the roof joists. Floor insulation is also essential in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the house as an additional 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 raised it may be necessary to dig out the floor to add the necessary insulation.
