Insulation

Garage conversions will often necessitate additional insulation as the garage space will be converted into a habitable room, and therefore has to comply with building regulations for insulation in this type of space. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofs. To comply with building regulations the garage conversion must meet the U-values in all of these areas, but additional insulation can be installed to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally performed by making use of internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and prevent heat from dissipating through the walls. Insulation must also be added around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs will demand insulation to the same standard as the rest of your home. Flat roofs also require insulation. This is done 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 installed above the roof joists. Floor insulation is also needed in garage conversions. This is easier if the floor level of the garage requires elevating in order to meet the rest of the house as an extra layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it may be necessary to dig out the floor to add the required insulation.
