Insulation

Garage conversions will often require extra insulation as the garage space will be converted into a habitable room, and consequently must adhere to 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, floors, and roofing. To comply with building regulations the garage conversion must meet the U-values in all three of the areas, but supplementary insulation can be added to surpass these values and increase energy efficiency. Wall insulation for garage conversions is normally done 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 be installed around windows and doors as these areas can leak heat particularly badly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same standard as the rest of the property. Flat roofs additionally require insulation. This can be 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 needed 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 doesn’t need to be lifted it may be necessary to dig out the floor to add the required insulation.
