Removable storm shutters and panels are designed to be 'put up' in the event of a hurricane or storm by placing them into a pre-installed panel mounting system over a window, door, or other area to be protected. The mounting system may incorporate a 'direct mount' hardware combination, or a more convenient, header and sill track.
Economical and easy to use, these products protect against flying debris and water penetration associated with hurricane force winds. Additionally, panels are available in various materials to suit application and budget. They are typically taken down and stowed away when not in use. Designed with convenience and storage in mind, removable storm shutters and panels are a huge advantage and recommended alternative to cumbersome "homemade", plywood shutters.
Panels come in aluminum, galvanized steel or see-thru polycarbonate materials. Aluminum panels are typically used in residential applications for the inherent light weight. Steel panels are more commonly used on very large commercial applications such as storefronts. Where needed, Willard provides a clear polycarbonate alternative to allow light to pass though the storm shutter. While effective, clear panels pose some limitations over other materials available, and consultation is recommended before specifying.
Panels may be installed using washer wing-nuts or spring clips. Spring clips are made of ¾ hard, 304 stainless spring-steel. Preferred track mounting hardware is a 410 stainless steel, ¼" diameter Tapcon® typically provided with tracks. In direct mount or removable track applications, hardware shall be nickel-plated brass, or stainless steel machine screw in conjunction with brass insert.
In all cases, header and sill tracks are mill extruded, heavy duty, 6063-T6 aluminum alloy, and cut to specified lengths based on the number of panels to be used per opening. They are typically provided with pre-determined, "factory drilled" mounting holes to facilitate simple and accurate installation. The extruded aluminum tracks are mill coated with a modified, acrylic/polyester enamel and cured at 400°F. All mill coated finishes pass recommended ASTM and AAMA standards testing.
- Economical and simple
- Can be made entirely removable
- Easy to carry, put up, and store
- Multiple materials and gages available to suit application and budget

With the effects of global warming upon us, architects and building owners need to mitigate its impact in the built environment. This is not a new idea, but the necessity for design that protects against volatile weather, rising temperatures, and insect-borne diseases is now more pressing than ever. Last year, the U.S. Army Corps of Engineers created the Building Resilience website, a tool that connects community planners, home builders, architects, and engineers with building science, climate data, and community resilience resources. This is crucial information designers and building owners need if they want to confront the effects of climate change.
As daylighting manufacturers, we have some thoughts on how daylighting can be used to reduce the impact of global warming on the built environment.
Daylighting that can withstand Severe Weather
Because of global warming, weather events like hurricanes, flooding, and tornadoes have become more powerful (Superstorm Sandy in 2012 and Supertyphoon Haiyan in 2013 have both been partly attributed to global warming).
But just because nature has become more dangerous doesn’t mean we should barricade behind steel walls. Instead, robust daylighting systems should be utilized. By incorporating daylighting into architecture, occupants remain connected to the outdoors, and the structure reduces its carbon footprint.
It’s important to use daylighting systems and materials that possess excellent water weepage and can withstand high wind loads. These attributes will be determined by the system’s glazing and framing.
Polycarbonate is one of the best forms of glazing when it comes to strength and durability, and it by far outperforms glass (polycarbonate is 250 times more resistant to impact than safety glass), as well as fiberglass reinforced panels, or FRP (polycarbonate is 4 times more resistant to impact than FRP).
Additionally, the system framing must have elements that facilitate excellent water control and leak resistance, like properly placed weep holes and water stops. An example of a highly resilient daylighting system is EXTECH’s LIGHTWALL 3100LSpolycarbonate wall system, which meets ASTM E-1886 and E-1996 tests for hurricane impact / windborne debris at clear spans of 8 feet. It is an excellent daylighting product in the face of torrential weather.
Protection Against Intense Heat
With global warming comes rising temperatures. Data has uncovered a long-term warming trend, and at this rate, temperatures could rise as much as 8 degrees by the end of this century (though that does not sound like much, a global increase in this scale would have dire outcomes). Even if carbon emissions worldwide are drastically cut, escalating temperatures are a factor humans must face.
With warmer temperatures comes the threat of increased solar heat gain (the temperature inside a structure that results from solar radiation). If precautions are not taken when choosing the daylighting glazing, people will either bake in a convection oven, or the cooling system will have to run at non-stop full capacity – neither choice is ideal. To protect against these scenarios, glazing that blocks infrared rays is recommended for daylighting structures. Polycarbonate is one of the few materials that can effectively and economically block infrared radiation.
Though humans can take many actions to reduce global warming, its effects will never be completely vanquished; mitigation is the only way forward. By accepting this, architects and building owners can be a leading force in climate change preparation – if they have the foresight now to build structures that deal with global warming’s impact, humankind will be safer, happier, and quite possibly, live to one day stop climate change for good.

The EconoSpan® louver and screen system is a continuous, "free-standing" louver product comprised mainly of roll formed louvers that snap firmly onto "double-gripped" stringers or posts installed on pre-determined intervals. This system is ideal for roof top equipment screening or other applications with large areas requiring concealment and ventilation. It is available in two major styles: Pitched Louver (both 45° and 22-1/2° pitches) and Flat Picket (both horizontal and vertical orientations).
Along with being very attractive, it is also one of the industry's most affordable systems. Using standard production components, the EconoSpan® system is designed and manufactured as required to be installed on a supporting structure. This allows the supporting structure to be provided locally, based on local code requirements*, yielding further cost savings. This simple "knock-down" product design allows it to be shipped as a kit in relatively small crates with step by step installation drawings making it convenient, simple and relatively quick for general contractors to install.

A new critical environment damper series from Ruskin® is designed and manufactured to withstand the elements of coastal and corrosive applications. The CD50CE and TED50CE combine the strength of stainless steel and protection of anodized aluminum to combat salt water elements.
“Our reps can now easily select a damper model with features suitable for coastal or corrosive applications,” said Mike Coyazo, commercial and life safety product manager at Ruskin. “Stainless steel linkage and anodized aluminum frames and blades come standard in these new models, making them perfect for harsh applications where salt water is present.”
The CD50CE is Air Movement and Control Association (AMCA) licensed as Class 1A and, thanks to low-leak extruded aluminum, meets the International Energy Conservation Code (IECC). The damper features low-maintenance, non-corrosive bearings and shake-proof linkage; airfoil blades for high-velocity heating, ventilation and air-conditioning (HVAC) systems, low pressure drop and quieter performance; and mechanically-fastened blade edge seals.
The thermal-efficient TED50CE eliminates thermal transfer and the potential for condensation. The damper also meets the IECC, features the same non-corrosive bearings and shake-proof linkage as the CD50CE and includes twin seals to ensure no thermal path.
The CD50CE and TED50CE are covered under the Ruskin five-year limited warranty program. The program – recently extended from one year to five years from the date of delivery – demonstrates the company’s commitment to quality and makes it easier for engineers to specify Ruskin products.

At Stanford, they inspire sustainable building solutions and the people who work in them. The Environment and Energy Building (Y2E2) continues to perform and provide a sustainable learning environment. The four-story building contains classrooms, offices, and labs that are filled with experts and students who are motivated by the efficient building in which they work, research and advance a variety of sustainable solutions for future generations to come.
The building’s ambitious energy goal called for more than a 50% reduction — above and beyond the ASHRAE 90.1.2004 requirement. According to the University’s website, the building capitalizes on the laws of nature for heating and cooling rather than using mechanical systems. In order to meet Stanford’s interest in creating a modern building, yet retain the classic look of the other structures on campus, Ruskin provided ELC6375DAX combination louvers/ dampers faced with ELF architectural grilles and a passive air management system. This provides constant airflow and outside air circulation.
How it Works
Known as the “lungs of the building” each of the four atria were treated to custom built stacked louvers to exact specifications.
Each atria rises up 89 feet (24 feet and 6 inches above the roof). At night, when the outside air drops to approximately 60ºF degrees, the ELC6375DAX louvers located at the top of the atrium act like a giant siphon and pull up the warm air and allow it to discharge out of the building. The louvers are integrated into a direct digital control system that analyzes the indoor air temperature and determines which windows within the building to open to let the hot air out.
In an interview with KGO-TV, Dick Luthy, Stanford Civil & Environmental Engineer Chairman said that process “will let the building naturally breathe and cool down.” This passive cooling system reduces the building’s energy contributing to the overall goal of 56% reduced energy usage.
The creation of this building was truly a collaborative effort where experts from a variety of disciplines came together to design a passive air management system that takes advantage of one of nature’s basic laws — hot air rises, cold air drops. The Environment and Energy Building is something uniquely special.
While the impact of this sustainable design will be felt daily by those who use the building, the far-reaching implications exceed anything that could be measured on a day-to-day basis.
“We felt this was one of the best investments that we could make for the next generation, and our children,” said Akiko Yamazaki, Yahoo! Co-founder, while standing in one of the trademark atriums during the building’s dedication. “For our children to be able to enjoy and experience what we’ve been blessed with, we cannot afford not to do something today.”
The building was constructed to LEED Platinum Standards and continues to perform as designed earning the LEEDEBOM rating (Existing Building Operations and Maintenance).
