Insulated Ballistic Glass

When you need safety from bullets and variable weather conditions, bulletproof insulated glass protects what matters most.

Defender Insulated Ballistic Glass - TSS

Protect Your Space with Bulletproof Insulated Glass

TSS' Defender line of insulated ballistic glass is made of at least two laminated glass panes separated by a sealed airspace, forming an insulated glass unit.

These insulated glass panels are easy to maintain, protective against firearms and forced entry, and great for natural light transmission. Considered a “new generation” of bulletproof glass, this material is quickly becoming a top choice for many industries, including schools, offices, municipal buildings, and more. Plus, Defender insulated ballistic glass from TSS can often be retrofitted into existing window frames, making it a perfect choice for building remodeling projects.

Is Bulletproof Glass a Good Insulator?

Bulletproof glass is thicker than standard window glass and its makeup often includes components that are good insulators, like thermoplastics. However, unless ballistic glass is designed to insulate, it won’t be the most effective temperature regulator. This is because the temperature can still transfer between the different layers of glazing, as there are no specific insulating elements.

Ballistic insulated glass is different. Unlike other types of bulletproof glass, bulletproof insulated glass has an air gap. This air gap provides a more efficient insulator, providing an element of thermal break, making windows suitable for exterior use. Total Security Solutions’ DEFENDER & GCP insulated glass units are ideal for exterior use in climates with both high and low temperatures, helping you achieve efficiency goals as well as bulletproof protection.

DEFENDER & GCP insulated ballistic glass is available in multiple thicknesses. The Defender line may be able to be retrofitted into existing frames, and both are compatible with TSS ballistic frames. Both lines can also be customized with tinting, Low-E, and other elements to enhance R-value.

How Does Insulated Ballistic Glass Compare to Other Options?

TSS’ ballistic insulated glass units are tested to UL 752 Levels 1 through 5. Bulletproof glass at these levels can withstand three rounds from various handguns up to one shot from a 7.62mm rifle. We also offer a forced entry only option.

Glass Type	UL Level	Application
Acrylic	1-2	Interior
Polycarbonate	1-3	Interior
Insulated Glass	1-5	Exterior
Glass-Clad Polycarbonate	1-5	Interior and Exterior
