Insulation

Garage conversions will often need additional insulation as the garage space will be converted into a habitable room, and consequently has to comply with building regulations for insulation in this type 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 of the areas, but supplementary insulation can be added to exceed 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 also be added around doors and windows as these areas can leak heat particularly severely. Roofs for garage conversions will additionally require insulation. Pitched roofs will require insulation to the same level as the rest of the property. Flat roofs also require insulation. This is 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 added above the roof joists. Floor insulation is also required in garage conversions. This is easier 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 lifted concrete floor, timber joists or a floating floor. If the floor does not need to be elevated it could be necessary to dig out the floor to add the required insulation.
