Insulation

Garage conversions typically necessitate extra insulation as the garage space will be altered to a habitable room, and consequently has to adhere to 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 three of the areas, but extra insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is normally performed 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 installed around windows and doors as these areas can leak heat especially poorly. Roofs for garage conversions will additionally require insulation. Pitched roofs need 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 prevent condensation forming. The other possibility 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 elevating in order to meet the rest of the house as an extra layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If the floor does not need to be lifted it might be necessary to dig out the floor to add the necessary insulation.
