Rationel offers high-performance windows and doors designed to deliver long lasting quality for many years. This series of videos demonstrates how our products are tested to meet the highest standards of security, durability and weather tightness.

To ensure Rationel AURA and Rationel AURAPLUS products can withstand even the worst rain and stormy weather, we expose the products for an extended water resistance test. View the test above.

Wear and tear test

Windows and doors are opened and closed many thousand times during their lifetime. To ensure a long life, the structures and fittings are rigorously tested by opening and closing them – again and again.

Wind resistance test

In order to ensure that our window construction can withstand extreme wind forces, they are tested under high pressure. In fact, we test the windows to a pressure equivalent to a hurricane.

Water resistance test

To ensure that our windows and doors can meet future storms and rains, they are subjected to a simulated storm in our test facilities. See how we test for water resistance in the video.

Secure by Design

Intruders can be a concern for any homeowner. Rationel offer Secured by Design certified windows and doors, specially designed to be extremely difficult and time consuming to break through.

During testing, our test staff are given 15 minutes to break open a window using a range of tools including knives, screwdrivers and crowbars. View the test result above.
