Insulation

Garage conversions frequently necessitate supplementary insulation as the garage space will be altered to a habitable room, and therefore must adhere to building regulations for insulation in this kind of room. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, floors, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is typically performed by employing 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 be installed around windows and doors as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of your home. Flat roofs additionally require insulation. This is 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 essential in garage conversions. This is less difficult 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 lifted concrete floor, timber joists or a floating floor. If the floor does not need to be raised it could be necessary to dig out the floor to add the required insulation.
