UPVC window frames: bevelled and feature – what’s the difference?

When it comes to replacing your windows, are you confused by all the different options? Home improvement companies become accustomed to bandying industry-specific technical terms and, in the drive to introduce customers to the latest product innovations, the basics can get forgotten.

Aluminium and uPVC window products are manufactured using extruded profiles. The profile is the cross-sectional shape of the frame. Admiral Windows’s standard Duraflex uPVC window frames are available in two profile shapes: bevelled and featured. What’s the difference between the two?

Feature frame

The feature frame profile is currently the most popular style. Otherwise known as ‘fully featured’, ‘quarter round’ or Ovolo, the frame edges curve toward the glass and incorporate dummy putty lines. The feature frame profile produces a soft look.

Bevelled frame

The bevelled frame profile is also known as a chamfered profile. Here, the frame meets the glass with an angled straight edge, giving what some regard as a sharper look.

Whichever window profile you choose, our Duraflex uPVC frames are available in a wide range of colours and woodgrain foils, and all benefit from advanced Q-Lon gaskets to maximise energy-saving – just like the gaskets fitted to high-end composite windows.

See sample uPVC windows in each profile style at the Admiral Windows conservatory show-site. We can be found within the Wyevale Garden Centre complex at Chilton.
