Frequently Asked Questions About Aluminium Windows
Are aluminium windows energy efficient?
Yes. Modern thermally broken aluminium windows can provide excellent energy efficiency.
SUNFLEX SAF windows incorporate a substantial polyamide thermal break designed to reduce heat transfer through the aluminium frame.
Depending on the glazing specification, SUNFLEX SAF windows can achieve U-values from 1.4 W/m²K with double glazing and 1.0 W/m²K with triple glazing†.
Are aluminium window frames slimmer than uPVC?
One of aluminium’s biggest advantages is its inherent strength.
This allows aluminium window systems to achieve particularly slim frames while accommodating large areas of glass, making them an excellent choice if you want to maximise natural light and enjoy more of your view.
Can SUNFLEX aluminium windows be triple glazed?
Yes. SUNFLEX SAF aluminium windows are available with either double or triple glazing.
Our team can help you decide which glazing specification is most appropriate for your property and what you want to achieve.
Can I have acoustic glass in aluminium windows?
Yes. Acoustic glass is available as a specialist glazing option.
If reducing outside noise is important to you, talk to our team and we’ll help you explore an appropriate glass specification for your home.
What colours are SUNFLEX aluminium windows available in?

If you’re looking for something different, your aluminium windows can be finished in any RAL colour for an additional cost.
Can I have different colours inside and outside?
Yes. Dual-colour options allow you to choose different finishes for the inside and outside of your aluminium window frames.
This gives you greater freedom to complement both the exterior architecture of your property and your interior décor.
