Insulation

Garage conversions usually necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently must comply with building regulations for insulation in this type of room. These regulations set a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, and roofs. To adhere to building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be installed to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally done by making use of internal wall insulation, which adds insulated plasterboard to the 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 severely. 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 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 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 lifted concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it might be necessary to dig out the floor to add the required insulation.
