"double door"

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.

When the Cincinnati Art Museum embarked on an $11 million renovation, the architects wanted the entrance and main stair to be as inviting as possible. Transparent, fire rated glazing from SAFTI FIRST® was a key component of the design solution. To maximize the vision area in door itself, SuperLite® II-XL 60 in GPX® Builders Series Temperature Rise full-lite doors. In some of the stairwell doors in less prominent locations, SAFTI FIRST® provided SuperLite® X-90 for the vision panels under 100 sq. inches.

SuperLite® II-XLM 120 clear butt-glazed walls with 9 ft. GPX® Builders Series 90 minute Temperature Rise doors creates a light-filled, transparent 2-hour stairwell that is on-brand with Waste Management’s new Houston Headquarters.

The David Eccles School of Business on the University of Utah campus features a 28- x 18-ft 2 hour interior glass wall with a 90 minute full-vision door in an exit enclosure/stairwell. The architects selected fire rated glass to meet fire rating requirements while providing maximum visibility and natural daylighting in the space. The project’s specifications also required the fire rated glass to have the same optical clarity as the adjacent non-rated glass systems.

The newly opened Exploratorium has brought energy and excitement to the city's bustling waterfront. EHDD transformed the historic Pier 15, built in 1915, to a 330,000 square foot indoor and outdoor campus, being touted as the largest net-zero building in the city and potentially the largest net-zero museum in the world. SAFTI FIRST® supplied a total of 19 pairs of 45-minute steel doors 11 pairs on north side and 8 pairs on the south side using SuperLite® II-XL 45 IGU in GPX® Builders Series Fire Protective.

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.

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.

Renovation stripping out the building completely and rebuilding the walls, Passive Purple® was applied in between the connections of the internal side of the external walls which were a combination of masonry, timber, and steel frame. The ground floor ceiling was removed exposing the warped old timber joists with cracks in the surrounding brickwork and mortar. This was given attention to detail using Passive Purple® Brush to seal above an airtight foam to guarantee the airtightness of this major air leak zone before the final spray coat of Passive Purple® airtight membrane was applied. Passive Purple® was also used to seal window and door linings, ready for the new triple glazed windows to go in. Passive Purple® was sprayed on all the walls and ceiling. This is an ongoing project that still is awaiting an air test, the client is looking to hit 2.5 ach and installing MVHR.

IntroductionSheet Steel Roong and SidingLightweight Steel FramingIsolate the Steel and Wood ComponentsAvoid Use of Pressure Treated WoodFastenersMany buildings will include wood members in applicationssuch as sill plates, splash boards, strapping, purlins, door orwindow bucks, and posts. In some of these end-uses it is arequirement that the wood be chemically treated (pressuretreated) to extend the service life.Designers and builders need to be aware that changes in theavailable wood perservatives may impact the durability ofany connected steel components or fasteners.Eective January 1, 2004 the Environmental ProtectionAgency (EPA) banned the use of Chromated CopperArsenate (CCA) as a preservative in treated lumber forresidential construction. This was done in an eort to reducethe use of chromate and arsenic thereby mitigating thepotential health and environmental problems. The woodpreservative industry has been switching to alternativewaterborne compounds including Sodium Borate (SBX),Alkaline Copper Quat (ACQ), Copper Azole (CBA-A and CA-B),and Ammoniacal Copper Zinc Arsenate (ACZA).Unfortunately, research has indicated that ACQ, CBA-A, CA-Band ACZA, the new generation copper-based products, aremore corrosive to galvanized steel than the former CCA.Since ACQ is becoming the predominant preservative in use,the discussions in this paper will refer to it exclusively.The purpose of this Fact Sheet is to convey the recommendations of the sheet steel industry for the application of steelproducts with ACQ pressure treated wood.
