Beautifully bespoke
Scandinavian windows

Our high performance Scandinavian style windows aren’t simply an accessory – they’re designed to fuel your life. You might be seeking sanctuary from the hustle and bustle of the everyday, or looking to dream beyond your usual horizon. You might seek shelter for your family, or crave that feeling of togetherness and tranquility. And it might sound crazy, but the right windows can bring all of that within reach.

Rationel Scandinavian windows bring together daylight, beauty and warmth to truly amplify your happy home. Highly energy-efficient as standard, they act as the catalyst to a totally comfortable and content environment, no matter what type of home you live in.

All of our windows are made entirely bespoke. We put the utmost care into every consideration, from colour and glazing all the way through to opening and closing functions, to create something that’s perfectly suited to you.

So whether you’re looking for a natural look from a sustainable source or a reliable option that is purpose-built to protect your home against the elements – not to mention the wear and tear that comes with frantic family life, look no further than Rationel.
