UPVC vs wooden casement windows – which one is the favourite?

wooden casement windows

The windows, doors and extensions you choose really do make a difference to the feel of your home, as well as its look. So, it’s imperative to get the design right first-time round, to avoid bitter disappointment and significant financial losses. 30 years ago, wooden casement windows fitted with double glazing were simply unheard of! With that in mind, you can understand the 80’s and 90’s uPVC replacement revolution that took the UK housing market by storm; almost selling themselves as the ‘must-have’ double glazed feature for the modern home. They also provided essential comfort, efficiency, additional value and maintenance-free qualities that had never been experienced before. Combined with the 1990’s Building Regulation changes, making double glazing a mandatory requirement in new builds, it made timber window suppliers pretty much obsolete overnight.

However, latest technological advances have transformed wooden casement windows into something rather different than its predecessors. Exceptional improvements to this classic window style are why we believe wooden casement windows are on the verge of overtaking the popularity of uPVC. Here are 5 reasons why:


Firstly, uPVC cannot replicate the air of sophistication and elegance that wooden casement windows truly excel at. This makes wooden casement windows most popular amongst homeowners who prefer the use of natural materials over uPVC.  You may not be aware, but timber is naturally insulating too, offering increased thermal efficiency over uPVC. Furthermore, our wooden casement windows can be constructed from sustainably sourced, specially treated softwood, hardwood and even oak.


uPVC is low maintenance, but it can’t be repaired as easily as timber. Incapable of fading or discolouration, with tender loving care your wooden casement windows could even outlive you; typically lasting around 60-80 years.


Anti-burglar type locking mechanisms make wooden casement windows virtually impossible to gain access to. Further security options include toughened glass and double or triple glazing, making sure that you really are ‘as safe as houses!’


Wooden casement windows are so versatile, they’ll literally suit any type of property. Especially prolific within period properties and those with large bay windows, they will truly enhance and improve upon your properties beauty ten-fold!  Wooden casement windows can also be manufactured to any specification required.

New Generation

Our new generation timber window is the only double rebated flush casement in the glazing market. Dedicated to innovation, all known flush wooden casement windows benefit from only a single rebate. This does not offer the weathertight benefits or air permeability performance that our new generation timber casement windows can.

Whether you have a period property or not, the Chase Window team look forward to meeting you at our flagship showroom or hearing from you soon to discuss your wooden casement window options in more depth.
