While aluminium is low maintenance, strong and adaptable to a variety of situations, the material itself is conductive, which means that heat can pass through it. By adding a thermal break or insulation to your aluminium windows or doors, the transfer of the outside temperature to the inside part of the aluminium is greatly reduced. This not only increases your energy efficiency but also helps combat condensation build up after long winter nights. Additionally, thermal breaks can have the added benefit of reducing sound reduction by dampening vibration.
