Insulation

Garage conversions often necessitate extra insulation as the garage space will be altered to a habitable room, and consequently must adhere to building regulations for insulation in this type of room. These regulations designate a U-value for insulation, which measures 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 three of the areas, but additional insulation can be added to exceed 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 pre-existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must also 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 the property. Flat roofs additionally require insulation. This can be performed utilizing 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 added 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 an extra layer of insulation can be easily added to either a raised concrete floor, timber joists or a floating floor. If the floor doesn’t need to be raised it might be necessary to dig out the floor to add the necessary insulation.
