Timber sub-frame

Aluminium windows can be placed within a timber sub-frame by fixing the window into a timber frame before being attached to the reveal. This means sightlines are slightly more restricted, however the slim profile of the aluminium balances this out. The main advantage of the timber sub-frame is that it adds traditional sophisticated aesthetic.

The benefits of Everest aluminium windows

Strong window hinges

Give your home a contemporary feel

Aluminium casement windows are the perfect choice for a contemporary feel. The slim frame allows for a larger glass area.

Stopping heat transfer

Aluminium's strength is it's great looks – but its weakness is its conductivity. At Everest, we have the experience to reduce this problem. We use all the technology at our disposal to limit transfer by incorporating a polyamide thermal break, a warm edge space bar between the panes and fitting Low-E glass as standard.

Safe and secure

Our aluminium windows offer excellent security features. Internal beading prevents the removal of glass from the outside, a multi-point lock and a key lockable handle that locks in a night vent position. So your home can be kept ventilated without compromising security.

    Polyamide thermal break

    We insulate our aluminium frames with a polyamide thermal break. Polymide is a specialist synthetic polymer strip that sits in the frame to block heat or cold transfer in and out of your home.


    Chamfered external bead finish

    All Everest aluminium windows come with a slim chamfered external frame finish. This ties in with the sharp modern aesthetic of the aluminium. This along with the two “feature grooves” provides a modern aesthetic to the frame..


    Gas between the panes

    Our sealed unit are filled with Argon gas. Denser than air, this reduces the temperature for improved energy efficiency. Most companies pump the Argon into windows by hand. At Everest our windows are assembled by robots in Argon filled rooms to avoid the gas from escaping.

Guaranteed for peace of mind

Everest aluminium casement windows have a range of comprehensive guarantees including a 10 year guarantee against fog and condensation between the panes. Everest also guarantee the window profiles and colour finish for 25 years and the whole window including furniture, gearbox and timber sub-frame for 10 years.

Aluminium window FAQs

At Everest, we understand that choosing new aluminium windows can be a daunting task. So to help you here are some frequently asked questions which you might find useful.

  • +
    Can aluminium windows be painted?
    In theory yes but we would not advise it as the best look will come from the original finish. Our windows are power coated which creates a very hard and resilient finish which should easily last for 20 years or more.
  • +
    Are Aluminium Windows better than uPVC?
    Aluminium tends to be stronger than uPVC, which means that the frame of an aluminium window can have a slimmer profile and larger glass surface compared to its uPVC equivalent. However, aluminium conducts heat and cold and so is not as thermally efficient as wood or uPVC which are far better at reducing temperature transfer through the frame.
  • +
    Are aluminium windows energy efficient?
    Although aluminium windows are strong and very attractive, the material has a weakness in regards to conductivity. At Everest we use our years of experience to reduce this problem. An Everest aluminium window is engineered with a polyamide thermal break (to reduce heat transfer), a warm space bar between the panes and Low-E glass fitted as standard.
  • +
    Can I have aluminium windows on a listed property?
    If you live in a listed property, when replacing any window, you first have to get consent from your local authority. There will be regulations stipulated to what materials i.e. timber frames and or sash style etc. Usually the stipulation is replacing like-for-like. There are a number of aluminium windows that can be made to match suitable properties. First step is to check with your local authority.
  • +
    Can you have triple glazing on aluminium windows?
    Unfortunately not. Aluminium windows have evolved over recent years, providing a stylish and sleek designs. If your property is particularly cold or susceptible to harsh weather conditions, then we would recommend installing triple glazing on uPVC windows.

Everest window reviews

5 star review for garage doors
I decided to have an old aluminium double glazed window replaced and I am so pleased with the replacement which was installed by Everest. co. uk. The work was carried out very professionally by two very experienced fitters who completely cleaned up and left my premises with a new super window set. I would recommend this first class Company to anybody for the installation of replacement windows. Thank you Everest. Leslie S. Derrick 31/7/18
