Flush Windows are quickly becoming the most popular choice for replacement windows.


With Timber being the original trend setter with a Flush finish it took a while before uPVC could attempt to mimic it's authentic design and thankfully they did take their time! Now being able to replicate a Timber effect with a woodgrain finish, uPVC have added a low maintenance option to the flush family. But let's not forget the newest member of the Flush family - Aluminium. Boasting slimmer sight lines than any other profile Aluminium is a must for contemporary homes.

Authentic Design

Flush casement windows have been specially crafted with traditional style, but now with advancements in technology they are safer, warmer and better looking than ever before.


  The original design of Flush Windows were made from Timber and what made them distinctive is that the opener was flush within the frame, creating a clean and simple look. This is very good for customers who want a slimmer frame on any material as the Flush fit creates a placebo of more glass to frame ratio.

We originally thought that only Cottage properties would suit Flush Windows but with the help of multiple colour options and Aluminium giving a nice clean slim look to the Flush family, architects are seeing the benefit of choosing Flush Aluminium Windows over any other material. 

uPVC helps the customers that want the authentic design but with a low maintenance window and thankfully with Mechanical Welded Joints and a realistic woodgrain finish uPVC is becoming a quick front runner for the traditional residential home

Energy Efficient

Treating Flush Windows like every other type of window at Decor, we made sure that it would keep your home warm!

Aluminium Flush Windows come with a Polyamide Thermal Break between the profile Thermal Break that improves Energy Efficiency by 30%. This gives our Aluminium Windows an A Rating by the BFRC and with Triple Glazing can be upgrade to A+

uPVC is known as the warmest windows and that is due to uPVC Chambers within the profile breaking down air as it tries to get through. Along with Double Glazing this helps our uPVC Windows achieve an A+16 Rating and with Triple Glazing can boast an A++21 rating.

Timber is a natural efficient window, as their are no Chambers needed or Thermal Breaks it proves that sometime nature wins. Accompanied with our Double Glazing gives our Timber Windows an Energy Rating of A+6 and upgrading to Triple Glazing helps us to achieve A+12.

We are sure at Decor you should see a reduction in your fuel bills no matter material you choose.

Flush Fit Security.jpg

At Decor as much as we care about the design of your Flush Windows, we believe security is no.1 when it comes to making that final decision. We only choose Casement Windows that are fully PAS24 compliant, this helps to deflect the attempts of the most persistent intruder and stop them from gaining unauthorised access to your home. 

Many companies boast a name next to their locking systems but really it all comes down to the security accreditation that’ll make your home as secure as it could be. When a locking mechanism has been tested too stringent measures like PAS24 it can give you the reassurance that your home will be able to rely on this extremely innovative security system to keep you and your family safe 365 days year.


To be PAS24 Certified the windows need to be put through certain tests to ensure they can opposed the opportunist burglar, the test complies of tools such as; small and large screwdrivers, paint scrapers and different sized crowbars used to try and break the locking mechanisms, when the locks have not been broken in a set amount of time then the locking mechanism is PAS24 Certified.

We hope that ensuring our Casement Windows being PAS24 Certified puts your mind at ease when you have Decor's Casements installed.

Glazing Options

Flush Windows are just like Casement Windows - many glazing options!

Having a wide range of glass choices at Decor, we ensure that you will make the right decision. In the past we have turned up to properties where a customer may have had different window installers in and the glass doesn't match, some have a different shade of reflection, for example - green, yellow and blue. This is because different window manufacturers use different glass suppliers - we make sure we know if you have Pilkington K, Saint Gobain or Guardian glass in your windows to choose the right glass supplier.

By knowing the 3 main glass suppliers, we a massive range of decorative & obscure glass you can be sure that there is the right design for you and that when it comes to privacy you have complete control on how private you want the obscurity to be.

We go on about security a lot and a glass option for you, to keep those intruders out, would be Laminated Glass. Able to withstand the hardest of hits, combined with our PAS24 locking mechanisms on our Casement Windows your windows will have the Secure by Design Status - the Police Security Initiative Scheme.
