Efficient and reliable


Fenster aluminium windows are made using Smart systems to produce only the highest performing aluminium windows. Aluminium is extremely strong and the slimmer frames are capable of holding much larger panes of glass, maximising natural light intake. They are available in a wide range of colours and finishes, and your choice of contemporary hardware.

Suitable for use in commercial and residential applications, our aluminium windows are guaranteed to reduce heat loss and exterior noise. They are designed to exceed current Building Regulations requirements for refurbishment projects and new build installations. Their excellent weather resistance is achieved by using 28mm sealed units featuring Polyamide thermal break technology. Fenster aluminium windows will keep any building warm, quiet, and secure 365 days a year.
