Insulation

Garage conversions frequently necessitate additional insulation as the garage space will be changed into a habitable room, and therefore needs to comply with building regulations for insulation in this kind 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 increase energy efficiency. Wall insulation for garage conversions is normally done by making use of 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 installed around windows and doors as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be done by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also essential 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 added to either a raised 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.
