Why Rationel Windows are a Brilliant Choice
So, you’re looking to purchase some new windows and want some independent guidance from a company which is not tied to one manufacturer. You’re in luck! In this guide, we look at why Rationel Windows offer a great choice of product for both your replacement windows or new build project.
Who are Rationel Windows?
First things first, you might be wondering, ‘who are Rationel Windows’? Rationel Windows (a sister company to Velux) is a Danish window manufacturer which only sells its products via approved distributors. This means that members of the public cannot purchase the products either directly from the factory or from their UK office.
What Products Do They Make?
Rationel manufacture both composite (low maintenance on the exterior timber) and timber only windows and doors which are made in automotive style factories using high-tech machinery. All windows and doors are completely bespoke: made to measure with a lead time of 6-10 weeks from the confirmed order, depending on the time of year (please check with us for exact timings).
Rationel creates windows using good quality materials and can consequently be considered in the mid-range price bracket amongst the products offered by Enlightened Windows. In addition, Rationel also provide a comprehensive UK guarantee for their products as standard, for added peace of mind.
The key ranges on offer from Rationel are:
Aura and AuraPlus: these are timber only and timber-aluminium windows respectively. The AuraPlus window is effectively the same as the Aura window in section, but also comes with a low-maintenance aluminium exterior, available in many RAL colours and, when purchased via Enlightened Windows, granite colours are also offered at no extra cost.
The Aura and AuraPlus bespoke windows from Rationel are particularly suited to modern-style buildings and have a flush exterior appearance. For more information and to see how they look in practice, check out the online brochure.
Forma and FormaPlus: These are timber and timber alu products respectively and are particularly suited to traditional-style buildings. These windows feature an angled and curved external glazing bead, and a chamfered internal glazing bead. There is also the option for a very slim 25mm glazing bar (commonly known as Georgian bar) which can often be found in traditional properties.
For more information, download the Forma and FormaPlus brochure.
Since Rationel’s windows are all bespoke, they can be made in a wide range of standard colours at no extra charge. As an added bonus, the windows are available in double or triple glazed options to suit your property, with a wide range of glass available for both added safety and solar heat protection.
Of course, when it comes to purchasing new windows, you need to feel confident that they are fit for purpose. Rationel test all window ranges to the rigorous standards below, so you can feel assured that your new purchase is truly durable and will deliver to the highest standards.
Wind Resistance: Standing Strong
Firstly, Rationel windows and doors are suitable for even the most extreme wind forces and the company regularly tests the product construction to the wind force of a hurricane, subjecting the windows to both positive and negative pressures of 2400 pascals. Thankfully, these are not conditions seen regularly in the UK but, rest assured, the product is fit for purpose!
Unlike many other manufacturers, who try to manipulate results by testing only a fixed window, Rational test a double opener. To see this in action, check out the video below where you can see the physical wind resistance test being performed.
Water Tightness: Not a Drop
In addition, with UK weather extremes regularly coming into the news, it is important that you carefully future-proof your window and door purchase.
In the video below, the test exposes the window to a wind speed of 27 metres per second and ‘moderate’ (!) rain in the form of 600 litres of water. Even after all of that, as you can see, the window didn’t leak.
Wear and Tear: Nothing There
Many windows sold in the UK suffer from poor-quality manufacture and poor-quality components. All of the products sold at Rationel Windows are extensively tested, ensuring that they would be happy to put these into their own homes.
Windows and doors are opened and closed many thousands of times during their lifetimes. As a consequence, quality hardware within the window is critical to ensure that the opening sash remains tight to the window, even after all this usage. Most UK-sold windows have no adjustment in the hinges and fittings but, with Rationel windows, most components are adjustable. So, if a window starts to stick slightly, it can easily be rectified (to find out more, see the Operation and Maintenance Manual Rationel provide with every purchase).
During the test below, a custom-built machine performs an open and close test. The machine opens, closes and rotates the handle repeatedly for 14 days in 20,000 opening cycles. As you can see, the window passed the test with flying colours thanks to its durable construction.
Security: Rock Solid
Finally, a key reason for choosing Rationel Windows can be found in their high standards for security. They are able to offer any of the above products as ‘Secure by Design’: an official police security initiative. In the test below, you can observe a failed break-in attempt against a Rationel window, performed using eight different tools and over a period of 15 minutes. This success for Rationel Windows again demonstrates why they are a truly smart and reliable choice for your next window purchase.
