At Rationel Windows and Doors Ireland, our products are known for their sophisticated design, but that’s not all. When you invest in our timber or alu clad windows, you do so knowing that they are also built to last. The Irish weather can be harsh at times, so it’s good to know that Rationel double and triple glazed windows are designed to stand up to the worst of it.

Even with minimal maintenance, Rationel replacement windows are designed to stand the test of time and they’re also very secure too. Our timber and aluminium windows are tested to meet the highest standards of security and safety, complete with all the latest security features to keep you, your family and your belongings safe from intruders.

As part of the testing and durability and testing phase, our double glazed windows are subject to 15 minutes of abuse from our team who are armed with crowbars, knives and screwdrivers. Needless to say, no one has made it through one of our sash windows or any of our other windows yet!

Wear and Tear
During their lifetime, windows are typically opened and closed thousands of times, which means that their structure, as well as their fixtures and fittings, need to be up to the task. This aspect of our replacement windows is also rigorously tested, with our designs enduring hours and hours of repeated opening and closing.

Water and Air Tight
Our windows are also designed to withstand high winds and sustained torrential rain, as well as being comprehensively tested o that we know that they can stand up to the worst winter storms up to hurricane strength. They’re literally stress-tested to their absolute limit at our test facilities. It’s the only way we can be completely sure that Rationel Windows are the very best on the market.
