Insulation

Garage conversions will often need additional insulation as the garage space will be converted into a habitable room, and consequently must adhere to building regulations for insulation in this type of space. 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 of these areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is normally performed by making use of 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 also be installed around doors and windows as these areas can leak heat particularly poorly. Roofs for garage conversions will also require insulation. Pitched roofs will require insulation to the same standard as the rest of your home. Flat roofs additionally require insulation. This can be done 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 less difficult 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 raised concrete floor, timber joists or a floating floor. If the floor doesn’t need to be elevated it could be necessary to dig out the floor to add the necessary insulation.
