Aluminium Windows Are The Future

It’s not looking good for PVC windows…

As you are no doubt aware the future is looking bleak for the PVC window market. With the cost and availability of resin throwing the future of the product into question, now is the time to start thinking ahead to offering an alternative.

As an aluminium window supplier, we have witnessed the growth of this product over the last few years, and it will continue to soar. Whilst we are seeing price increases on both ali and PVC window options, the rise in PVC is more significant and looks set to continue well into next year.

The gap in price difference is closing between ali & PVC, making aluminium windows a more viable option for homeowners across the UK.

Make no mistake, now is the perfect time to embrace aluminium and start offering it to your customers. Aluminium affords you better margins than uPVC, it’s also a superior product that will result in fewer callbacks.

Below is a reminder of the 5 aluminium window options we offer. We offer flexible deposits on all window jobs and competitive prices.

Smart Eco Futural (Opal Tilt & Turn) Windows

Opal Tilt & Turn windows are high-performance windows suitable for use as tilt & turn, pivot casement, fixed and open out casement windows. They are most common for commercial applications but are also a great alternative for residential properties too.

The obvious benefit of tilt and turn windows is that they can be made in larger sizes than standard casement windows. These come in handy when a customer wants sashes bigger than the maximum, or a full height floor to ceiling window that can tilt for ventilation.

These windows are also a good choice for first floor or balcony windows, where they can be specified to tilt only. This will ensure the windows are compliant with current building regulations.

The Smart Tilt & Turn window is a versatile product that is perfect for both residential and commercial projects.


  • Well suited for a wide range of commercial and residential uses
  • Can achieve much larger sizes than standard windows, great if the customer wants oversized opening sashes
  • Tilt only function for balcony and upper-level windows


  • More costly than standard casement windows
  • Opening inwards sashes are not always suitable
