Flush Casement Window

Our flush casement window frames reflect the charm of the wooden casement windows of traditional cottages. 

Besides restoring authentic heritage style to a period home, these windows can also bring understated sophistication to modern properties.

Sculptured Casement Window 

GreenCastle sculptured casement window frames have a gently curved shape that, like flush windows, look as good in newer homes as they do in older houses.

More rounded and styled, than diagonal bevel-cut frames, the sculptured-edge design can be configured to almost any size or layout, including bay windows and bow windows.

Chamfered Casement Window

The slim, bevelled shape of our chamfered casement window frames is ideal for replacing wood or aluminium frames or upgrading early-generation uPVC windows.

The clean, crisp shape of the double-chamfered edge design has both classic aesthetic appeal and a contemporary, sleek look that works well with modern or minimalist architectural styles.

Noise Reduction

Double-glazed casement windows can reduce the effects of exterior noise pollution inside your home by up to 65 percent. With two panes of glass sandwiching a layer of insulating air or argon gas, our casement windows soak up sound vibrations.

Energy Efficiency

GreenCastle casement windows have one of the best energy-efficiency ratings. This means they prevent a lot of heat loss, resulting in lower energy bills and a reduced carbon footprint. During warmer weather, our casement windows will keep your home cooler.

Glazing and Frame Options

As well as double glazing, GreenCastle offers triple-glazed uPVC casement windows in Edinburgh that provide even better insulation performance. 

Triple glazing is more expensive but could be a good investment for the chilly winter months. We also offer timber or aluminium frames as an alternative to uPVC.

Detailing and Colours

GreenCastle can customise your casement windows from a range of design detailing options such as Georgian-style bars and stained-glass windows or other types of leaded panes. 

The fresh, clean look of white window frames is a traditional choice but you can personalise your casement windows with coloured frames, including shades of cream, tan, grey, or brown.

Casement Windows Edinburgh - FAQs

Most frequent questions and answers

Casement windows are the traditional, most popular choice to replicate classic window styles, and they have multiple, versatile design and detailing options.

They can have single or double panels. They open and close on side hinges, like a door, or on hinges at the top (awning windows) or bottom (hopper windows).

Casement window frames are available in uPVC, timber, or aluminium. UPVC is the most popular choice.

Double-glazed casement windows with uPVC frames can last 25 to 30 years, often longer if they’re maintained properly and have been supplied and fitted by a reputable window company like GreenCastle.

Maintenance is basically just cleaning panes and frames, and making sure locks and hinges are working.

Casement windows are one of the lower-priced types of windows. Pricing varies according to the size of the window, quality of materials, and level of customisation.
