Product Testing

Testing is at the heart of our philosophy on what makes a good window and door.

We are committed to producing windows and doors that are as enduring as they are beautiful and, as such, engage in a continual programme of product testing.

What we test?

Across our Traditional, Historic and Contemporary Ranges we rigorously test the following performance measures:

  • Weather tightness
  • Thermal performance
  • Security
  • Operational and strength
  • Acoustic performance

The benefits of testing

Testing allows us to continuously strive for optimal product performance. Our wooden windows and doors are designed and built for long-life and minimal maintenance and through testing we are able to provide reassurance through awarding manufacturer-backed guarantees.
