Insulation

Garage conversions will often need supplementary insulation as the garage space will be altered to a habitable room, and therefore has to adhere to building regulations for insulation in this type of space. 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 adhere to building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be added to exceed 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 poorly. Roofs for garage conversions will also require insulation. Pitched roofs will demand insulation to the same standard as the rest of your house. Flat roofs also require insulation. This can be done by using a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other option 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 elevating in order to meet the rest of the home as an additional layer of insulation can be easily put into either a elevated concrete floor, timber joists or a floating floor. If flooring does not need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
