Fire-rated systems

ACUSTI GLASS fire-rated wall systems combine advanced safety with contemporary design. They are available in various fire resistance classes – EI 15, EI 30, EI 60, and EI 120 – allowing precise adaptation to specific project requirements. Offered in both single- and double-glazed versions, these systems provide reliable fire protection while ensuring excellent acoustic comfort. With their minimalist form and elegant appearance, they integrate seamlessly into modern interiors, guaranteeing safety without compromising on style.

What are Fire-Rated Systems and how do they work?

ACUSTI Fire-Rated Systems provide certified fire-resistant glazing solutions designed to protect people, property, and evacuation routes while maintaining visual openness and architectural aesthetics.
These systems combine structural safety, transparent fire protection, and modern design, making them ideal for office buildings, public facilities, hotels, residential complexes, corridors, staircases, and high-risk environments.

We offer a complete range of EI-classified systems, engineered to prevent flames, smoke, and heat from spreading — while offering the same visual quality as premium interior glass walls.

Together, they form a versatile safety solution suitable for commercial buildings, exit routes, lobbies, atriums, hallways, and demanding architectural spaces requiring certified fire resistance.

This comprehensive range allows us to meet the needs of architects and investors who require both design continuity and rigorous safety performance throughout the building.

What fire-rating classes are available? +

Our systems comply with the EI classification, offering protection as follows:

  • EI 15 / EI 30 / EI 60 / EI 120 — depending on the selected model

  • Available in both single-glazed and double-glazed variants

  • Matching variants: Horyzont I, II, III, Loft modules

This means high-rise glazing applications up to 3 000 mm in height, ensuring fire safety in both standard and demanding architectural zones.

Which design options are available? +

  • Slim stainless-steel or aluminium profiles (e.g., 40 mm in the Horyzont system)

  • Choice of single or double glazing units

  • Finish in any RAL colour or anodised effect

These options let you maintain a unified interior design, even in zones with fire-rated requirements.
