Plus, with them being manufactured within the UK, it makes damage during transportation much less likely.


What is the difference between casement windows and flush casement windows?

Regular casement windows have parts that extrude on the exterior of a building, whereas flush casement windows sit flat on a wall. They both have very similar technicalities. The difference in these windows is predominantly cosmetic. If you would like to learn more about the windows we offer, please contact a member of our team!

Which is better, uPVC or timber?

Both these materials have good arguments as to why you should use them. The lifespan of both of these products can be very similar if they are correctly maintained. A pro of choosing uPVC over wood is that uPVC is a lot simpler to keep, with most uPVC only needing a quick wipe down now and then.

If you want wooden windows, their upkeep can become very pricy due to their liability to rotting, warping and cracking in harsher weather conditions. However, wooden windows often suit the architecture of heritage homes better than uPVC simply because they have a more rustic look and feel.

How secure are flush casement windows?

Casement windows are significantly challenging to break into. This is because a casement window frame is flush with the window. Plus, these windows can only be opened from the inside. They can’t be opened from the outside, even using a crowbar. Your customers will also feel knowing our flush windows are BBA approved, PAS24 accredited and SBD awarded.

Are flush windows worth it?

Their insulation properties are excellent, and your customers may save on energy bills. They are even more air and watertight since they are flush with the wall. Along with providing excellent performance, they also offer excellent slim sightlines, bespoke glazing platforms and a range of customisation like cills, colours and size for customers to enjoy.

Your customers have endless customisation options with the beautiful range of different colours and styles these flush casement windows offer. If your customers are looking for a timber-like appearance without the poor maintenance, these mechanically jointed windows offer the perfect answer.
