Insulation

Garage conversions usually necessitate additional insulation as the garage space will be altered to a habitable room, and consequently has to comply with building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which measures the rate of heat loss. These are set differently for walls, flooring, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all three of these areas, but additional insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by using 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 also be installed around windows and doors as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of the property. Flat roofs also require insulation. This can be done by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other option is a warm roof, where insulation is added 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 home 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 may be necessary to dig out the floor to add the required insulation.
