Flush Sash Casement windows are different from traditional casement windows in that the opening sash is recessed into the frame to create a flush uniform appearance. This is different from typical windows where the window opening sash overlaps the frame sections of a window and appears to sit on the outside.
Flush Sash or Timber look casement windows have been around for many years in timber and more recently in PVCu. Companies such as Residence 9, Liniar and others all offer excellent quality PVCu flush casement options.
Where are flush casement windows suitable?
Flush casement windows are ideal if you have old timber windows and are keen to retain the original aesthetics of the wood windows where the sashes sit in the frame and not outside them.
They also fill a gap in the market for those whose budget does not stretch to the additional cost of real wood windows but still want a traditional looking alternative. The PVCu windows are ideal but what is the alternative if you either don’t like PVCu windows generally or you are aware of the benefits of aluminium windows?
Are Aluminium Flush Casement Windows available?
If you are looking for an aluminium flush casement alternative to your original wood windows there are presently have two options available.
Hybrid windows are a combination of aluminium outside and wood inside. These again are at the top end of the price range but offer a fantastic window whereby you have all the advantages of powder coated aluminium outside and the warm tactile feel of real wood on the inside.
Aluminium Flush Casement Windows
These are still relatively new to the market and presently only available by Origin the leading manufacturer of bifolding doors. The Origin Window is the first all aluminium flush casement window and unique within its particular sector.
What is best? Aluminium or PVCu casement windows?
As with any purchase of new windows, customers will have certain criteria, such as budget, performance of the window and overall aesthetic appeal. The Origin Window replicates the traditional and much loved lines of 19th Century styled wood windows but is also suitable for contemporary properties. If the overall look of a flush casement window appeals to you then no matter what type of property you have it will suit your needs.
Sight lines of aluminium flush casement windows
Aluminium Windows generally are chosen for their superior strength, ultra slim sight lines and the advantages of polyester powder coating which is far superior to the PVCu plastic gloss finish.
With aluminium flush casement windows you will get thicker sight lines than a typical slim aluminium window but these are designed to replicate original timber windows which were never intended as a slim window.
Therefore whether you choose a flush casement window or a typical slim casement where the sashes overlap the frame will be down to personal preference. Some properties may suit windows with thicker sight lines perfectly, others may not.
It is important to remember that aluminium windows and doors are preferred by homeowners and architects designing or renovating many contemporary homes owing to its flatline modern appearance. Flush casement windows may be ideal in such scenarios.
Aluminium windows have one huge advantage over pvcu
All modern windows whether aluminium, timber or PVCu, come with their own guarantees and how long they will last. What has long been accepted is that the powder coated finish found on aluminium windows will last much longer and look better for longer. But why is this?
PVCu flush casement windows will either come in the standard PVCu white profile or in a choice of foils to achieve the real wood appearance. They are also available as coloured windows achieved again either by using a flat surfaced coloured foil or via a wet paint process.
By comparison, aluminium windows are polyester powder coated. This is a finishing process that has been used commercially on aluminium windows, doors, screens and much more for over 40 years.
This powder coated finish has stood the test of time and even windows and doors that have been installed and in regular use for over three decades continue to look good.
Technological advancements in powder coating technology also means that aside from the typical 15 or 20 year guarantees available as standard, there are also powder coated paint finishes that can have special guarantees for severe or coastal environments, city centre environments as well as special guarantees if windows are being installed around swimming pools or areas with chlorine and other contaminants. This is a huge advantage over PVCu and PVCu foiled windows.
What about wood effect aluminium windows?
If you desire wood effect aluminium windows, these are available with a wood effect finish that can be considered superior to the foiled finish of PVCu.
Wood effect aluminium windows are available from many manufacturers that utilise the very latest in sublimation technology. This “dye transfer” technology is an improvement over foiled plastic windows for several reasons:
1. Most PVCu foiled systems cannot apply the foil to the internal faces of the windows such as those seen when the windows are open. Aluminium windows can.
2. The process used in aluminium windows is a very durable paint finish and not a foil
3. If you are looking for matching windows and bifolding doors these are often not available from many of the PVCu systems
4. Should the wood effect finish on aluminium be damaged, it can be repaired much easier than a foiled window.
