Insulation

Garage conversions will often require extra insulation as the garage space will be altered to a habitable room, and therefore has to comply with building regulations for insulation in this type of room. 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 meet building regulations the garage conversion must meet the U-values in all three of the areas, but extra insulation can be installed to surpass these values and improve energy efficiency. Wall insulation for garage conversions is typically performed 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 added 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 level as the rest of your house. Flat roofs also require insulation. This is achieved using a cold roof system, where insulation is fixed between the roof joists along with ventilation to prevent 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 elevating in order to meet the rest of the house as another layer of insulation can be easily added to either a elevated concrete floor, timber joists or a floating floor. If flooring doesn’t need to be elevated it may be necessary to dig out the floor to add the necessary insulation.
