Despite being thinner and lighter than uPVC the material is very tough and very difficult to penetrate. Aluminium frames will accommodate all locking systems and are mechanically robust. They are also easier to repair than equivalent uPVC windows in the event a mechanism needs to be changed.
In a fire situation, aluminium windows are highly inert and don’t burn. Instead, the material melts only when it gets above 600 degrees C. In a fire event aluminium naturally conducts heat without spreading or encouraging flames.
Fitting new or replacement aluminium windows offers many positives. When compared directly with uPVC windows there is not a lot between these two materials quality-wise. In terms of efficiency, modern aluminium frames perform as well as any other material. For that reason, the most significant factor to consider is the glazing choice. In terms of cost, although not the cheapest, the price difference is falling. And ultimately, influences such as the style and size of the window might still draw you toward aluminium. Particularly if you are looking for more glass than frame.
