Insulation

Garage conversions typically necessitate additional insulation as the garage space will be converted into a habitable room, and consequently has to comply with building regulations for insulation in this kind of space. These regulations set a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofs. To meet building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically done 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 installed around windows and doors as these areas can leak heat especially severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same standard 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 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 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 put into either a elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be lifted it may be necessary to dig out the floor to add the necessary insulation.
