Smoke Screens DH30 / D180 with Concealed Fixings: Elevating Fire Safety with Seamless Design
As buildings become more open, complex, and interconnected, managing fire and smoke movement is not just a code requirement it’s a design necessity. Among the most effective passive fire protection solutions available today are glass smoke screens rated for DH30 and D180 classifications. When paired with concealed fixings, these solutions provide both technical reliability and architectural elegance.
What Are DH30 and D180 Smoke Screens?
Smoke screens are vertical or horizontal glass barriers designed to delay or control the spread of smoke during a fire. They’re classified based on the duration for which they maintain integrity against heat and smoke exposure:
- DH30 – Smoke screen that retains smoke and heat resistance for 30 minutes.
- D180 – Enhanced smoke screen rated for 180 minutes (3 hours) of containment.
These ratings are defined and tested under EN 12101-1 and EN 1364-1 for smoke control systems, ensuring their effectiveness in real-world fire scenarios.
Why Smoke Screens Matter
In fire events, smoke travels faster than flames, often causing more fatalities due to suffocation, poor visibility, and confusion. Smoke screens:
- Delay smoke movement into escape routes.
- Improve egress time for occupants.
- Channel smoke toward extraction systems.
- Assist firefighting teams with visibility and control.
They're essential in atriums, shopping malls, airports, lobbies, high-rise corridors, and elevator shafts.
The Advantage of Concealed Fixings
Traditionally, smoke screens were supported by visible framing, steel brackets, or clamped hardware that compromised visual minimalism. Today’s design-forward projects require more safety with aesthetics.
Concealed fixing systems allow:
- Clean glass-to-glass or glass-to-wall connections
- Minimal or no visible metal components
- Flush installations within walls or ceilings
- Preservation of open, transparent spaces
This makes concealed-fix smoke screens a perfect fit for:
- Premium commercial interiors
- Iconic public spaces
- Projects with high aesthetic demand
Performance Meets Aesthetics
Glass smoke screens with DH30 / D180 ratings are typically made from multi-laminated fire-resistant glass such as SCHOTT PYRANOVA® or equivalent, which:
- Maintain integrity under high heat
- Remain optically clear or sandblasted for privacy
- Support large panel sizes without distortion
- Can be used in curved, angled, or sloped applications
These are often integrated with ceiling-recessed track systems, stainless steel channels, or frameless mountings to achieve seamless installations.
