Insulation

Garage conversions will most likely require 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 type of room. These regulations designate a U-value for insulation, which measures 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 the areas, but extra insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally accomplished by using 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 be added around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of your home. Flat roofs additionally require insulation. This is performed utilizing 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 raising in order to meet the rest of the home as an extra layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If the floor does not need to be elevated it might be necessary to dig out the floor to add the necessary insulation.
