Authentic Appearance

UPVC Casement windows are available with slimline frames making them very stylish. Wood-grain surfaces only enhance that stylish appearance by replicating the look and feel of traditional timber made casement windows.

Finished Surfaces

Alongside super smooth uPVC frames, casement designs can also feature coloured textured surfaces that replicate timber. These wood-grain finishes are bonded into the material so that they do not fade peel or crack.

Low Maintenance

UPVC casement windows are renown for being easy to look after. No sanding or painting like you need with timber. The surface simply needs to be washed down if it gets dirty. Hinges & handles are designed for long lifespans.

Storm Proof

The latest casement windows in uPVC are independently tested to meet all kind of British Standards of weather proofing. Meaning you have a product that keeps out wind and rain, no matter how bad the UK weather gets.

Sound Reduction

Double glazed, or triple glazed casements are superb for reducing the amount of noise from the outside of the property. Compared to single glazed unit, a double glazed window can reduce noise pollution levels by up to 70%.

Excellent Security

Strong key lock handles and multi- point hooks are the first level of security. This is backed up by internal window beading designed to prevent removal of the glazed panes by burglars. Stainless steel hinges also add security.

Design Flexibility

From a single window to an elegant curved bow window. Casement designs can be used in almost any situation for any size of window. You can combine opening sections in virtually any configuration that you can think of.

Colour Range

Why stick with white? Casement windows in uPVC can be found in a wide variety of colours to suit your property. Wood colours, such as Oak, Mahogany or many plain colours. Also a selection of wood-grain colours.

Choosing which casement window opens

Deciding which window casement opens and which direction it opens is important in 2 ways.

  1. Price impact
  2. Function & “usability”

casement windows openerFirstly, price impact. Giving a glazed section the ability to open means more detailed work at the manufacture stage and can therefore potentially increase the cost of the whole unit.

It’s common practice for a lot of installers / manufacturers to add a charge for each panel that can open, so check for this extra charge.

Secondly, function: You can have side or top hinged opening casements. The location of the window can influence which section you want to open.

For example, in a lounge room, you may only need a small top hinged opener at the top of the frames. In a kitchen you may want a larger side opening section, plus a top opening section.

The location of the opener in the frame can also make a difference. If we take the kitchen window again as an example, would it be more convenient to have the opening window section on the left hand side or the right hand side?

  • Take some time to consider what works best for each of your rooms.
