Finstral is one of Europe’s leading manufacturers of premium windows, doors and glass wall systems, renowned for combining exceptional design with outstanding performance.

Alongside refined design, Finstral doors are built to deliver outstanding performance. High levels of thermal insulation help maintain indoor comfort and energy efficiency, while durability is ensured through robust construction and precision engineering. Security is a key priority, with reinforced locking systems as standard, including steel hook bolts, secure hinges and tamper-resistant cylinders.

Fast forward 2 and half years later and one of our bedroom windows cracked when it was slammed shut in the wind. We contacted Banbury windows and conservatives to ask about getting it fixed, we sent them the info they needed and they emailed us to say the window had arrived and they would be out to replace it free of charge. We wasn’t expecting that at all. Absolutely top notch service and after care from start to finish. We will always use Banbury windows and conservatories in the future.
