Over the past years, Deceuninck has invested heavily in research and product development, creating new products from the ground up and challenging ourselves to do things differently.
We’re pretty obsessive about quality and detail. We don’t want to make products that are simply “good enough” or look much the same as everyone else’s. We want them to stand out, whether that’s through performance, design, security, durability or simply how easy they are to work with.
That’s where our Best-in-Class approach comes from.

For years, patio doors have been treated as something of a commodity. Our previous patio door did the job, but we knew we could do more with it.
We wanted to create a patio door that performed exceptionally well, looked great and was still straightforward for fabricators to make and installers to fit.
That became Slider24.
It achieves Class A4 air permeability at 600Pa, Class E8A water permeability at 450Pa and Class A3 wind resistance at 1200Pa.
That’s impressive performance, but the important thing is what it means in a real project. Developers get a patio door that can meet demanding performance requirements without compromising on the look, and fabricators get a product they can confidently put forward when they’re competing for work.
And that’s really what we’re trying to achieve with our products, something that works just as well commercially as it does technically.

Our Fully Reversible Window (FRW) came from a similar idea.
We wanted to create a window that could handle the demands of modern high-rise and apartment property developments, while giving fabricators something a little different to take to the market.
It achieves PAS24 security, 1050Pa water tightness, 600Pa air permeability and 2400Pa wind loading. Thermally, it can reach a 1.2 U-value double glazed and 0.8 U-value triple glazed, using our patented BlueForce steel wire foam technology.
It can also go up to 1.4m x 1.4m, with an 80kg weight limit, making it a good fit for larger openings and taller buildings.
It’s a product that gives fabricators another way into commercial projects where performance really matters. In fact, some of our customers call it a “tender breaker and margin maker”, which is a pretty good description of what we were trying to achieve.

Of course, not everything needs to look ultra-modern.
Our Heritage Flush Sash has the traditional, clean appearance that works so well on everything from country-style homes to modern townhouses, but underneath it has all the performance you’d expect from a modern window.
It achieves a 1.2 U-value, PAS24 security, 600Pa air permeability, 300Pa water tightness and 2000Pa wind resistance.
So if you’re installing or fabricating for a project where the appearance of the windows is important, but you still need to meet demanding performance requirements, you don’t have to choose one over the other.

We also know that colour is becoming much more important to property developers, installers and fabricators.
The right colour can completely change the look of a building, but specifying colour can sometimes create problems. Longer lead times, minimum orders and the need to hold more stock can all make things more complicated than they need to be.
We wanted to make it as easy to order colour as it is to order white.
We now have 30+ colourways available from stock, including matching trims, cills, end caps and ancillaries. And, importantly, colour is available on the same lead time as white. With Deceuninck, there’s no need to order huge quantities months in advance just to secure the colour you want.
If you need a single length of coloured profile for the next delivery, you can order it.

Ultimately, we’re not developing new products just for the sake of having something new to talk about; we want to make products that solve real problems.
That’s what Best-in-Class means to us.
