Insulation

Garage conversions often 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 room. These regulations specify 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 three of these areas, but extra insulation can be installed to surpass these values and improve 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 prevent heat from dissipating through the walls. Insulation must also be added around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level as the rest of your house. Flat roofs also require insulation. This can be achieved using 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 installed above the roof joists. Floor insulation is also essential 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 put into either a elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be raised it could be necessary to dig out the floor to add the required insulation.
