Secured by design

At Rationel, we understand that security is a valid concern for any homeowner. That is why all of our windows and doors are Secured by Design, designed to be extremely difficult to break through and provide the maximum level of protection for you home.

As a part of this rigorous quality and durability testing, our staff are given 15 minutes to try and break open a Rationel windown using a range of tools – including knives, screwdrivers and crowbars.
