The Safe Choice

Ultimately, it doesn’t matter how pretty or energy efficient a window or door is if it isn’t secure. Nothing else matters if it can’t keep a burglar out and your family safe.

With Lumi, security is just as much a focus as our breathtaking looks and energy efficient design. We use only the strongest materials to make our products, and with our tripled glazed windows offering a 50mm toughened glass glazing unit and 70mm fibreglass frame, you can sleep easy knowing that your house is protected against threats. Our triple glazed windows also offer our UK exclusive brake lock system from Winkhaus, which allows you to lock your window in any opened position using the handle.

Of course, our door ranges are also not lacking when it comes to security features, achieving secured by design, meeting the police standards for security.  All our Lumi doors come with anti-pick, anti-snap, anti-drill locks, leaving our doors with no external weak spots and leaving your house and leaving your family safe.

For windows that look the part, without compromising on security Lumi is second to none.
