Partners In Wildlife
As part of our commitment to environmental responsibility, we have committed to Partner In Wildlife status. Suffolk Wildlife Trust supports a number of projects local to us to improve biodiversity and encourage re-wilding. Through our partnership, we hope to aid them both physically and financially.
Sustainable and secure
Our Rationel windows and doors are not only sustainable, but are also exceptionally secure as standard. All products achieve Building Regulations Approved Document Part Q as well as Secured by Design certification.
Tested to the extreme
Our Velfac windows and doors are market leaders in air, wind and water tightness. But don't just take our word for it; the full range has independent certification from 3rd party test houses.
93% fully recyclable
We make sure to choose products and suppliers who look after the environment. So you can rest assured that by choosing okoHaus products, we've done the research for you.
Durability, tested to the max
Full durability and cyclic testing is an important part of product development and factory quality control. We want your windows to stand the test of time and receive minimal call-backs, so nothing is left to chance.
Wind tested for the most severe locations
Our Rationel products are tested and certified to extremely high levels of wind resistance, giving you peace of mind that they are more than up to the job of keeping you cosy and warm when the weather turns nasty.
Installation detailing to match
When specifying high-performance window systems like ours, an equally high-performance installation system is well worth the investment. That's why we offer the Illbruck range of sealant and air tightness solutions.
