Insulation

Garage conversions typically require extra insulation as the garage space will be converted into a habitable room, and consequently needs to adhere to 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, floors, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be installed to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by using 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 also be added around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of your house. Flat roofs also require insulation. This is done 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 added to either a elevated concrete floor, timber joists or a floating floor. If the floor does not need to be raised it may be necessary to dig out the floor to add the required insulation.
