    Best windows for concealing heat and preventing draughts

    Window Specialists

    Are aluminium framed windows good at concealing heat and preventing draughts getting in? Are they any better than windows that use other materials for their frame or is it purely down to the strength of the window glass?

    "Hi Kelly

    Yes modern up to date Aluminium frames are just as good as UPVC frames when it comes to energy efficiency as they all now have a thermal break within the aluminium frame and sashes, so when coupled with Low-energy glazing that's standard nowadays that creates an excellent window frame option to go for, needless to say, though all windows need to be fitted correctly in the first place as even the very best windows will still let drafts in if fitted badly.

    Best regards

    "Hi, Aluminiumm windows are not good at concealing heat. Any metal is not a good head conductor unfortunately but plastic and timber raw materials are a great heat conductor as you can imagine. Upvc and timber units show the greatest efficiency for energy bills being reduced. Aluminium in my opinion is only for looks, but if you have the means and resources to ensure heating is in place OR you have a trusted source of installation for aluminium to ensure they have correctly installed it, then you won’t find much heat loss even with aluminium. At the end of day, it all comes down to the quality of the raw materials and the installation being the final process.

    Window glass strengths can be achieved the same throughout various raw materials used for windows and doors. Something called ‘toughened glass’ also now as safety glass, is the strongest form of glass manufactured till date. There are 100’s of types of glass out in the market today and choosing the right glass is determined by the right supplier and installers.

    We are a manufacturer and installer of windows and doors across all raw materials available. We have been in the industry for more than twenty five years.

    Please don’t hesitate to drop me an email for a quotation on our company website (sunrise composite doors) or contact me on this to discuss further.

    I’ll be happy enough to speak further.

    Many thanks

    "With aluminium frames, the problem that you have is that metal is a conductor of heat and cold - so the frame itself is actually transmitting cold into your home from outside. Hardwood timber or PVCu window frames do not have this property.
    The most energy-efficient windows are double glazed, with either wooden or PVCu frames. Also look for a warm-edge spacer bar (within the window itself - sometimes these are made of aluminium, which again transmits the cold into your home), and glazing units with an Argon-Gas-Filled cavity."
