Insulation

Garage conversions will often need supplementary insulation as the garage space will be changed into a habitable room, and consequently needs to comply with building regulations for insulation in this type of space. These regulations set a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, floors, 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 installed to exceed these values and increase energy efficiency. Wall insulation for garage conversions is normally performed by using internal wall insulation, which adds insulated plasterboard to the pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also be installed around windows and doors as these areas can leak heat particularly poorly. Roofs for garage conversions will additionally 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 performed 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 required in garage conversions. This is less difficult if the floor level of the garage requires raising in order to meet the rest of the home as an extra layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If the floor doesn’t need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
