Insulation

Garage conversions often necessitate additional insulation as the garage space will be altered to a habitable room, and therefore has to adhere to building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which gauges 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 improve 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 prevent heat from dissipating through the walls. Insulation must be installed around windows and doors as these areas can leak heat especially badly. Roofs for garage conversions will additionally require insulation. Pitched roofs need insulation to the same level as the rest of the property. Flat roofs also require insulation. This can be 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 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 another layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If flooring does not need to be elevated it might be necessary to dig out the floor to add the required insulation.
