Insulation

Garage conversions often necessitate additional 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 space. These regulations designate a U-value for insulation, which assesses 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 the areas, but supplementary insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is normally 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 added around windows and doors as these areas can leak heat particularly severely. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same level 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 possibility is a warm roof, where insulation is installed above the roof joists. Floor insulation is also essential in garage conversions. This is easier if the floor level of the garage requires raising in order to meet the rest of the house as an additional 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 lifted it might be necessary to dig out the floor to add the necessary insulation.
