At Quality Glass Block, we’re proud to offer innovative fire-rated glass block with our fire-rated window / impact patterns and F-120 wall block that combine safety, durability, and style for homeowners, contractors, and builders navigating strict building codes. As a trusted provider, we’ve partnered with Seves Glass Block to deliver products that meet rigorous standards like ASTM E-119, UL 263-19, and CAN/ULC S101-14, achieving up to a 2-hour fire rating. Here’s why our glass block solutions are transforming modern construction projects.
Exceptional Fire Protection and Strength
We design our fire-rated impact windows and F-120 wall block to withstand extreme conditions. Available in 60-minute, 90-minute, and 120-minute fire ratings, these products cater to diverse building code requirements. Our 2-hour fire-rated F-120 wall block stands out, rigorously tested to endure fire exposure for up to two hours. This makes it ideal for critical areas like firewalls, stairwells, and corridors where safety is non-negotiable.
Stylish Patterns with Practical Benefits
We understand that aesthetics matter as much as safety. That’s why our fire-rated glass blocks come in five distinct patterns: Nubio, Clarity, Endura, Spray, and Wave. These options allow you to balance privacy, light transmission, and design in any space. Here’s a glimpse of what we offer:
- Available in 60-Minute: Nubio, Clarity, Spray — all are 8x8x4 size
- Available in 90-Minute: Nubio, Endura, Clarity — all are 8x8x4 size, accept Clarity also has a 6x6x4 size
- Available in 120-Minute: Wave and Clarity — both in the 1919/13 (19cm x 19cm x 13cm) size

Compliance with Strict Building Codes
We know that meeting fire codes is critical, especially in urban projects. The F-120 Wall Block is tested to ASTM E-119, UL 263-19 and CAN/ULC S101-14 standards for up to 2-hour fire-rating, making it a top choice for schools, hospitals, and commercial buildings.
Beyond fire protection, our blocks offer sound transmission control (STC ratings up to 50) and impact resistance, addressing noise and safety concerns.
