Insulation

Garage conversions often necessitate additional 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 room. These regulations specify a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, floors, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all of these areas, but extra insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically performed 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 installed around windows and doors as these areas can leak heat particularly severely. 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 also require insulation. This is done by 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 elevating in order to meet the rest of the home 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 required insulation.
