Fire Rated Glass Helps SFPUC Building Achieve LEED Platinum

The new San Francisco Public Utilities Commission Headquarters combines maximum daylighting and fire safety with a multi-story, fire rated glass stairwell from SAFTI FIRST®. Dubbed as the "greenest building in North America," this Class A LEED Platinum office building features a transparent, 2-hour fire rated stairwell, situated prominently near the main entrance. SAFTI FIRST® supplied SuperLite II-XL 120 in GPX Architectural Series Wall Framing and SuperLite II-XL 90 in GPX Builders Series Temperature Rise Door starting from the lobby all the way to the topmost floor.

Fire Rated Curtain Wall Performance in Dramatic Weather Conditions

As far as extreme environments go, Wisconsin has some of the most dramatic in North America. During the winter months, temperatures regularly dip well below freezing, and in the summer months the temperatures can reach up to 90 degrees Fahrenheit with significant humidity levels for extended periods of time. Given these dramatic weather conditions, the materials chosen for the building envelope should not only protect building occupants from the elements, but ensure their comfort as well.

Fire Resistive Curtain Wall Helps Hospital Meet Fire and Seismic Requirements

Ratcliff was chosen as the architect to design the new three-story, 60,000 square foot San Jose Downtown Health Center that includes urgent care for adults and children, primary care for pediatric, OB/GYN and family medicine, behavioral health services, laboratory, pharmacy and radiology departments. Their design takes advantage of glazing’s ability to draw natural light from the outdoors to create a warm, pleasing atmosphere that promotes healing. Part of the hospital’s exterior curtain wall had to be fire rated for one hour and meet seismic requirements per SB 1953 as well.

Fire Resistive Glass Opens New Doors for Adaptive Reuse Project

Adaptive reuse, or the process of taking an old building or structure and repurposing it for something other than what it was originally designed for, has gained a lot traction with developers and architects alike – and for many good reasons. For one thing, it is more economical and sustainable to work with an existing structure than to demolish an old building, clean up the site, and rebuild with entirely new materials. It also helps preserve historical structures that add character to the community, as well as reduce urban sprawl. For the multifamily sector, we’ve seen adaptive reuse applied to old schools, government buildings, warehouses, etc. because these structures are usually centrally located in many downtown areas.

Clear, Fire Resistive Butt-Glazed Walls Create Transparent, Connected and Code-compliant Stairwell

The University of Wisconsin School of Business Grainger Hall’s east and west wings are now linked by a state-of-the-art Learning Commons that encourages collaboration through technology and design. To achieve maximum transparency while meeting code requirements, the architects specified 9 ft. tall, clear, fire resistive butt-glazed walls using SuperLite II-XLM in GPX Architectural Series perimeter framing.

Fire Rated Glazing Gets Visitors ‘In the Spirit’ of Historic Bourbon Distillery

As America celebrated National Bourbon Day on June 14, downtown Louisville also celebrated the highly anticipated grand opening of the Old Forester Distillery. This event is also touted as a triumphant return of America’s first bottled bourbon in continuous production by the same family before, during, and after Prohibition to Whiskey Row. See how SAFTI FIRST® fire rated glass walls helped create an immersive visitor center with a fully operational distillery, cooperage and bottling line.

A Clear Solution for Harvard’s Klarman Hall

This new 120,000 square foot, state-of-the-art convening center features a 1,000-seat auditorium that is large enough to host the entire MBA class. The glass atrium floods the multi-purpose lobby with natural light, as well as provides a visual connection between the interior of the building and the outdoor environment. To maximize transparency, SAFTI FIRST met with the architects during the design phase to create a large, 2-hour, glass wall that separates the lobby from the auditorium while providing a visual connection between them. Since this 2-hour glass wall also serves as the entrance to the auditorium, deciding on a 90-minute door system was of upmost important. SAFTI FIRST’s in-house engineering department provided design assistance, system details, engineering calculations and support from the planning phase all the way to the submittal process.

Enhancing the #TargetRun with Oversized Fire Resistive Butt-Glazed Glass Walls

Who hasn’t uttered the words or at least heard of a “Target run”? What started out as a marketing campaign to get more foot traffic in their brick and mortar stores has become somewhat of a cultural phenomenon. Aside from being a call-to-action, #TargetRun is a trending hashtag used by shoppers to share their in-store shopping experience on social media.

Fire Rated Glass Transforms Retail Parking Garage with Natural Light and Vision

Traditional parking garage designs used to have opaque fire rated building materials like concrete, masonry and drywall which made these spaces dark, cold and uninviting. That all changed, thanks to the emergence of new technology, clear, fire resistive glazing tested to ULC/CAN S101 up to 2 hours that are available in large sizes and low-iron glass make-ups with high visible light transmission for superior clarity and color neutrality.

Chicago Starbucks Reserve Turns Stair-Climbing Into Unforgettable Experience Using Fire Rated Glass

The Starbucks Reserve Roastery in Chicago features an incredible, 4-story mural by local artist Eulojio Ortega. The mural, brilliant for conveying the story as visitors go from floor to floor, is interestingly located in an exit stairwell.  Traditionally, stairwells are enclosed in opaque walls, leaving them dark, isolated, and rarely utilized unless in an emergency.  To allow the mural to be visible through multiple floors, encourage stair usage and meet fire rated code requirements, the architects redesigned the 2- hour stairwell using transparent, floor-to-ceiling butt-glazed glass walls with the largest tested and listed fire resistive glass panels available.

USA-made Fire Rated Glass Helps UC Merced Achieve Triple Zero Sustainability

The Merced 2020 Project, an ambitious, $1.2B, extensive expansion of the UC Merced campus, is “the largest public-private partnership social infrastructure project completed in U.S. history,” according to the university’s website. This includes new facilities used for academic, administration, laboratories, housing and recreation. This was truly exciting, and it struck a chord with SAFTI FIRST® because Merced is home to our manufacturing facilities.
