The weather in Ireland is tough. The wind and rain can take its toll on your home’s exterior, which is why it’s so important to have durable composite doors and double glazed windows installed. At Rationel, our range of alu clad windows offer the kind of durability that makes them able to stand up to the worst conditions Ireland’s weather can throw at them and stay looking great for decades after they’re installed.

Passive House

Our double and triple glazed windows aren’t just good looking either, as they meet Passive House standards for heat efficiency, allowing them to retain so much of the heat generated by your home’s powered heating, that energy bills can be cut by as much as 90%. The knock on effect of this is lower carbon emissions from every building they’re installed in and eventually, a cleaner environment for everyone.

Tradition of Excellence

At Rationel Windows and Doors Ireland, our replacement windows are the end result of 60 years of engineering excellence and are at the cutting edge of sustainable design. Our products are ideally suited for Ireland’s climate, protecting those inside on the one hand and making use of solar gain energy on the other. They are the perfect blend of style and functionality and are available in a wide range of colours and finishes.

If you would like to see what we mean by engineering excellence in person, you should visit one of our 5 showrooms, located across Ireland. Inside you’ll see working examples of our innovative products in real settings.
