Insulation

Garage conversions will often necessitate additional insulation as the garage space will be converted into a habitable room, and therefore has to adhere to 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 roofing. To meet building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally done 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 be added around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same level as the rest of the property. Flat roofs also require insulation. This can be performed 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 installed 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 house as another layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be lifted it could be necessary to dig out the floor to add the required insulation.
