Insulation

Garage conversions often require extra insulation as the garage space will be changed into a habitable room, and therefore has to comply with building regulations for insulation in this kind of space. These regulations designate a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofing. To comply with building regulations the garage conversion must meet the U-values in all of these areas, but additional insulation can be installed to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by making use of internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must be installed around doors and windows 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 your house. Flat roofs additionally require insulation. This is achieved 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 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 lifting in order to meet the rest of the home as another layer of insulation can be easily added to either a elevated 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.
