Insulation

Garage conversions typically require additional insulation as the garage space will be converted into a habitable room, and therefore must adhere to building regulations for insulation in this type of room. 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 of these areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically accomplished by employing 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 doors and windows as these areas can leak heat especially badly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of the property. 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 option is a warm roof, where insulation is added above the roof joists. Floor insulation is also needed in garage conversions. This is easier if the floor level of the garage requires lifting in order to meet the rest of the house as another layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor doesn’t need to be lifted it may be necessary to dig out the floor to add the necessary insulation.
