Blast Resistant Glass FAQ

Blast resistant glass is typically specified in:

• Government and military buildings
• Airports and transport hubs
• Embassies and diplomatic facilities
• Corporate headquarters
• Banks and critical infrastructure
• Public buildings in high-traffic or high-profile locations

OAG works closely with architects and security consultants to integrate blast mitigation into façade and interior glazing.

Blast resistant glazing is tested according to international standards such as:

• ISO 16933 – Explosion resistance testing
• GSA/DoD and ASTM F1642 – US government blast standards
• EN 13541 – European standard for explosion-resistant glazing

Tests involve controlled detonations to simulate real-world blast conditions, measuring glass deflection, retention, and frame performance.

No — modern blast resistant glass is virtually indistinguishable from standard architectural glazing. It can be clear, tinted, or frosted, and used in curtain walling, doors, partitions, and façades. This allows architects to maintain visual clarity and minimalism while delivering high levels of protection.

Blast resistant glass is typically made using:

• Multiple layers of toughened or laminated glass
• Polyvinyl butyral (PVB) or ionoplast interlayers
• Specialised structural silicones and framing systems
• Rigid anchoring systems to prevent glass ejection

These elements work together to contain breakage and reduce blast effects on occupants and assets.

Yes. In many high-security environments, glass may need to meet multiple performance criteria. Multi-functional glazing systems can combine blast resistance with fire protection, bullet resistance, acoustic control, or thermal insulation — all fully tested and certified for combined use.

Yes. Blast protection is not just about the glass — the framing and anchorage system must also resist and absorb pressure. OAG designs and installs certified blast-resistant framing systems, ensuring the entire assembly — not just the glass — meets required performance levels.

In many cases, yes. OAG provides retrofit solutions that allow existing buildings to be upgraded with blast-resistant systems. This may involve replacement of units and frames. We assess each project individually to determine the most efficient, compliant approach.

Blast resistant glass is heavier and more complex than standard glazing due to its layered composition. Installation requires specialist equipment, detailed engineering, and experienced teams. OAG manages the process end-to-end, including structural checks, logistics planning, and certified installation.

OAG is an experienced provider of secure glazing systems for sensitive environments. We understand the balance between safety, appearance, and regulatory compliance. Our blast resistant glass solutions are delivered with precision, discretion, and full documentation — ensuring peace of mind for high-risk applications.
