Insulation

Garage conversions typically require additional insulation as the garage space will be altered to a habitable room, and consequently must adhere to building regulations for insulation in this kind 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 roofing. To adhere to 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 typically accomplished by making use of internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be added around windows and doors as these areas can leak heat particularly badly. 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 performed utilizing a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent condensation forming. The other option 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 home as another layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it may be necessary to dig out the floor to add the necessary insulation.
