Insulation

Garage conversions usually require additional insulation as the garage space will be converted into a habitable room, and consequently needs to comply with building regulations for insulation in this type 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 roofs. To meet building regulations the garage conversion must meet the U-values in all of the areas, but supplementary insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is typically 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 particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of your house. Flat roofs additionally require insulation. This can be performed by 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 raising in order to meet the rest of the home as another layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor does not need to be raised it could be necessary to dig out the floor to add the required insulation.
