Insulation

Garage conversions will most likely necessitate supplementary insulation as the garage space will be changed into a habitable room, and consequently has to comply with building regulations for insulation in this kind of room. These regulations specify a U-value for insulation, which assesses the rate of heat loss. These are set differently for walls, flooring, and roofing. To adhere to building regulations the garage conversion must meet the U-values in all three of these areas, but supplementary insulation can be added to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically done by making use of 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 be added around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same level as the rest of your home. Flat roofs also require insulation. This can be performed 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 easier if the floor level of the garage requires raising in order to meet the rest of the home as another layer of insulation can be easily put into either a raised concrete floor, timber joists or a floating floor. If flooring does not need to be lifted it may be necessary to dig out the floor to add the necessary insulation.
