Why choose Zenith

Our Quality

To make sure that our customers receive 100% excellence every time, we set rigorous quality control standards. These are just some of the many tests we carry out daily to ensure that only the highest quality windows, doors, garage doors or conservatories are installed in your home:

• Our unique state-of-the-art Environmental Test Chamber uses computer technology to reproduce the conditions of a warm living room, and extreme weather conditions.
• With the Met Office, we've studied the weather cycles for the last 30 years and subjected our samples to similar patterns.
• We use Weld Testing Equipment to check the quality of welds, and a Salt Spray Cabinet to ensure a high quality of metal fittings.
• Our Security Test Rig simulates the damage that a burglar might inflict and the results are assessed to ensure high standards of security are met.
• Secured by Design is the Association of Chief Police Officers crime prevension initiative, of which we are official licencees.
