Insulation

Garage conversions often necessitate extra insulation as the garage space will be altered to a habitable room, and consequently has to comply with building regulations for insulation in this type of space. These regulations designate a U-value for insulation, which gauges 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 of these areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by using 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 added around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same standard as the rest of the property. 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 prevent condensation forming. The other possibility is a warm roof, where insulation is installed above the roof joists. Floor insulation is also required in garage conversions. This is easier 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 added to either a raised concrete floor, timber joists or a floating floor. If flooring does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
