Benefits of Ballasted Roofing

John Hamati, director of technical services for American Hydrotech Inc., says the term ballast often refers to stone as the ballast, but it’s not necessarily exclusive to stone. “A ballasted roof will have the membrane installed first onto the approved substrate, then followed by the XPS Styrofoam insulation and then the proper overburden,” Hamati says. XPS Styrofoam insulation is a closed cell polystyrene that is highly moisture resistant. Placing it on top of the roofing membrane offers protection from the harsh roof environment. American Hydrotech only uses XPS in their assembly as it can resist moisture.

Roof Assemblies: A Paradigm Shift

In roofing assemblies for low-slope concrete roof decks, Protected Membrane Roofs set the bar for cost savings, labor efficiency, and roof life span among other advantages. These, advantages may appear counterintuitive: common sense suggests the roof's waterproofing covering needs to be on top, protecting all the other components of the assembly from the elements of nature, including the insulation. Nonetheless, the primary moisture barrier (or waterproof roof covering) itself tends to be the weak link when exposed to environmental stress.

Waterproofing a Sports & Entertainment Complex in Inglewood, California

SoFi Stadium, home of the Los Angeles Rams and Los Angeles Chargers, is the first indoor-outdoor stadium to be constructed and is currently the NFL’s largest, at 3.1 million sq.ft.  The $5 billion stadium can seat a maximum of 100,000 guests, and includes 12 club spaces, a 6,000-seat performance venue, a 2-1/2 acre covered outdoor plaza, and a dual-sided elliptical video board with integrated sound system.  SoFi stadium utilizes a unique single-layer ethylene tetrafluoroethylene roof, which is a highly transparent extruded film that is just 1% the weight of glass.  The massive venue is truly a one-of-a-kind stadium, thanks in large part to the materials that were used to build it.

Moisture Absorption in Polystyrene Insulation: Effects on In-Serive Design R-Values
Moisture absorption is a familiar concept. It is easy to understand moisture absorption mechanisms in polystyrene insulation. Unfortunately, some insulation-performance claims can be misleading when based on test results from a few field samples or extrapolations of long-term field performance from small-scale laboratory tests of limited duration and exposure.
Ideally, engineers and specifiers would have access to peer-reviewed data from known scientific institutions to sort through the marketing claims. Sophisticated mathematical modeling is emerging to help predict polystyrene insulation performance in a range of climate conditions, but in the meantime, long-term field research studies are the best resource for reliable information.
This article originally appeared in the November 2020 issue of IIBEC Interface.

Statue of Liberty Museum - Featured Project of the Week on

Gracing the entrance to New York Harbor and welcoming millions of immigrants to the United States since 1886, the Statue of Liberty was a gift of France designed by Bartholdi and Eiffel. The Statue of Liberty Museum is the most monumental addition to Liberty Island since the Statue herself.

More than that, it allows millions more visitors to enjoy the Statue of Liberty experience and be inspired by her history and message of freedom and opportunity. While the Statue of Liberty remains New York’s most iconic monument, the museum housed in its base had long proved inadequate for the thousands who visit each day.

Innovative Green Roof Project "The REACH" in Washington DC is a Technical Masterpiece

The John F. Kennedy Center for the Performing Arts is a historic venue, standing on the bank of the Potomac River in Washington D.C. The facility recently underwent a $250 million expansion called The REACH expansion, which is a true state of the art project.

The project incorporates an expansive landscape over structure containing a technical masterpiece: a three-dimensional cork-screw green roof for the public area of the project as never seen before. It was the result of a unique collaboration between designers, contractors and material suppliers. The Steven Holl Architects-designed project opened in October 2019 and has already achieved LEED Gold certification.

Garden Roof Benefits Patients at Pediatric Hospital in Palo Alto, California

Palo Alto, CA. (November 26, 2019) There are many reasons to incorporate a green or living roof into a design, including energy conservation, water management, and financial benefits.  For one project in Palo Alto, California, the benefits of having a green roof transcended financial gains, and instead served a higher role.

The REACH - Featured Project of the Week on

WASHINGTON, D.C. (November 14, 2019) The Kennedy Center’s first expansion since its opening in 1971, the REACH is the John F. Kennedy Center for the Performing Arts’ historic, $250 million expansion project.  A living memorial for President John F. Kennedy, the REACH is envisioned as a 21st-century cultural campus and arts incubator and the 4.6-acre site is located on a former parking lot for buses.

Visitors can walk through a 35 ginkgo tree grove anchoring the south end of the campus (Kennedy was the 35th U.S. president), watch a free outdoor simulcast performance projected on a wall, or stroll to the reflecting pool and mahogany landscape deck which is built in the same dimensions and mahogany boards of Kennedy’s WWII torpedo patrol boat, the PT109.
