Security Casement Windows

Windows can let in much more than light. Don’t allow them to become the weakness in your security that criminals exploit. Our security casement windows are a first for the UK. They look just like any other casement window but conceal security features that will stop most would-be intruders in their tracks.

Wood Finishes with Concealed Steel Frames

Wood is beautiful, but it’s high-maintenance and easily splintered or broken. Although our security casement windows feature steel frames and reinforcements, they hide their impervious secrets behind engineered wood finishes.

Expect durability. This game-changing wood-based product carries a 50-year guarantee against cracking, warping, shrinking or swelling. Choose your finish and colour from our extensive RAL palette and achieve the perfect look for your home or office.

Security or Bulletproof Glass

Smashing our P6B security glass windows presents a challenge few would-be intruders will be equal to.

Armed with an axe or hammer, they’ll need to direct between 30 and 50 forceful blows at your windowpane. There’s no quick, easy way they’ll gain entry. For those with advanced security requirements, upgrades to bulletproof glass are available.

Top-Quality Window Locking Systems

Completing your casement window security, multipoint locking leaves potential invaders firmly outdoors. Easy breaking and entering is a thing of the past when you choose our security casement windows.

Double Glazed for Energy Efficiency

Our security windows are certainly non-standard. Instead, they set the standard. Energy efficiency requires double glazing, and our windows support your energy-saving needs.

Fully Customised for You

Although you’re aiming for enhanced security, you’d also like to enhance your home or building’s appearance. With Stronghold Security, you’re guaranteed a solution that meets and exceeds both of these requirements. Your design choices coupled with our built-in security features mean you get the look you want most while still enjoying a high level of security.
