Insulation

Garage conversions frequently need supplementary insulation as the garage space will be altered to a habitable room, and consequently has to adhere to building regulations for insulation in this type of room. These regulations specify a U-value for insulation, which measures 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 of the areas, but extra insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally accomplished by employing 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 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 standard as the rest of your house. Flat roofs additionally require insulation. This is performed 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 added above the roof joists. Floor insulation is also needed in garage conversions. This is less difficult if the floor level of the garage requires lifting 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 lifted it could be necessary to dig out the floor to add the necessary insulation.
