Insulation

Garage conversions will often need extra insulation as the garage space will be converted into a habitable room, and consequently has to adhere to building regulations for insulation in this kind of room. These regulations designate a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofing. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but additional insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is normally done by employing internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must also be added around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will additionally 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 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 required in garage conversions. This is less difficult if the floor level of the garage requires raising 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 doesn’t need to be lifted it may be necessary to dig out the floor to add the necessary insulation.
