Insulation

Garage conversions frequently need extra insulation as the garage space will be altered to a habitable room, and consequently has to comply with building regulations for insulation in this kind 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 comply with building regulations the garage conversion must meet the U-values in all of these areas, but supplementary insulation can be added to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally accomplished by making use of 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 doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of your house. Flat roofs additionally require insulation. This is done utilizing 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 installed above the roof joists. Floor insulation is also essential in garage conversions. This is less difficult if the floor level of the garage requires lifting in order to meet the rest of the house as another layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be lifted it might be necessary to dig out the floor to add the necessary insulation.
