Rationel – Window Manufacturers in Ireland


For over 30 years, Rationel Windows & Doors has been one of the leading window manufacturers in Ireland. With a tradition started 60 years ago in Denmark, Rationel has constantly improved techniques and methods so that we have both the product and expertise to meet today’s demanding standards for windows and doors. Design, quality, performance, energy efficiency and security are but some of the considerations when choosing your windows all of which are to the fore in the Rationel range of products.

We understand the importance of having a quality window and with our practical knowledge of what works and what doesn’t we can advise you so you will maximise the benefits of your new windows or doors. If you favour wooden windows, we’re proud to recommend our modern timber windows, high on performance, available in three translucent wood stains or many solid paint colours. Our Rationel Domus range is perfect for modern new houses, but also when replacing those old windows on houses built after 1970. Or if you prefer an aluminium finish, which has the benefit of completely minimising maintenance, we highly recommend our Rationel Aldus range, aluclad windows that will suit your preferences if you want flexibility in terms of colours on the interior and exterior. For more traditional tastes, sash windows and classic designs are most suitable. We’re pleased to put forward our Patus+ alu clad windows, designed with both appearance and energy efficiency in mind. The satin feel of these windows is created by their aluminium clad with 30% gloss finish. But we would never underestimate the beauty of classic timber windows, which we have achieved with our Patus range.    

Thanks to today’s technology, windows are energy efficient in that a quality window will significantly reduce your energy bill, by keeping heat in or out, and by soundproof your home. Double glazed windows are our standard, but for colder facades, we always recommend triple glazed windows, which will significantly reduce any thermal loss.

Whether you are building a new home, refurbishing an existing one or just simply replacing your windows and doors we will assist you through the process and make sure you make the decision that will meet both your needs and budget.

Windows and doors impact on both the external and internal look of your home. They need to be a reliable barrier against our ever changing climate whilst also protecting your home from intrusion. There is much to consider so please avail of our expertise in making your decisions easier. In Ireland, find us in Dublin and Cork.
