At Rationel Windows and Doors Ireland, we know more than a thing or two about manufacturing high quality composite doors and double glazed windows, however, our expertise does not end there. That’s because we also offer highly durable, bespoke garden windows and doors, allowing you to truly enjoy your outdoor spaces without actually having to go outside!

Whether you have ambitions of creating a traditional conservatory or a contemporary area which allows you to bring some of the outdoors inside, we have timber and alu clad windows to suit. Let’s just have a quick look at what we mean.

Increased Sunlight
The great thing about our aluminium windows is that they are bespoke, meaning that they can be fashioned to meet whatever requirements you have. Many of our customers like their replacements to allow more sunlight in, to make their home a brighter and more welcoming place. What this also does is allow more solar warmth to be retained during the winter, meaning you’re less likely to need to use your heating.

Hard Wearing Style
Another desirable element you get when investing in replacement windows from Rationel is a mark of durability. When chosen with aluminium cladding, our garden windows need next to no upkeep to allow them to retain their stylish and contemporary appearance. Just a regular wipe down is all you’ll need and they’ll look as good as new!
