CorruBracket 100T from S-5! is designed specifically for corrugated roofing profiles that are common in North America. CorruBracket 100T is affixed to the crest of the corrugation, leaving the drainage plane free of holes to protect against leaks. The bracket can be attached directly to the sheeting, accommodating ancillary attachment anywhere along the corrugation. For heavy-duty applications, the bracket can be fixed into the underlying substrate for additional support without crushing the corrugation. CorruBracket 100T comes with a factory-applied EPDM rubber gasket seal already on the base; the S-5!-patented reservoir conceals the EPDM from UV exposure.

Eighty-two Daylighting Systems were installed in the renovated 16,533-square-foot building, formerly an abandoned retail boutique at the corner of 44th Street and Van Buren in Phoenix.
“The use of the Daylighting Systems was an integral part of our sustainability and lighting energy savings plans for the renovated space,” says Dave Elrod, regional manager of DPR Construction, Phoenix. “The products are a cost-efficient solution to provide lighting since they nearly eliminate the need for artificial daytime lighting.”
In addition, the roof is composed of foam with an R-25 insulation value (approximately 4-inches thick) over plywood sheathing.
DPR Construction is a national technical builder specializing in highly complex and sustainable projects. In less than 10 months, the design-build team researched, designed, permit-ted, and built a highly efficient and modern workplace with numerous innovative sustainability features.
In addition to natural daylighting, the office features an 87-foot zinc-clad solar chimney, which releases hot air from the building while drawing cooler air in; shower towers that act as evaporative coolers to regulate building temperatures; 87 operable windows designed to open and close automatically (based on indoor/outdoor temperatures); and two “vampire” shut-off switches to keep electrical devices (radios, cell-phone chargers, microwaves) from using plug energy when no one is in the office.
Access to the building was limited during construction. Spray foam roofing, which took about seven days to complete, had to be done in small quadrants because of the tight schedule as work was progressing in the other sections. The roofing workers were challenged by the barrel-shaped roof, which created footing difficulties, and the many penetrations that had to be flashed, including all PV support legs, Solatubes, skylights and HVAC penetrations. Work was completed in the middle of winter, so additional protections and efficiencies were required.
The circa-1972 building has been officially certified as a Net-Zero Energy Building by the Seattle-based International Living Future Institute through its Living Building Challenge program. It also has received LEED-NC Platinum certification from the U.S. Green Building Council, Washington, D.C.

UNITREX 2.67- by 7/8-inch and 4.2- by 1-1/16-inch polycarbonate panels are impact-resistant and provide long-term protection against denting, cracking and peeling. UNITREX polycarbonate panels are UV-resistant, offering an advantage compared to other siding and roofing panels. UNITREX polycarbonate panels have a non-combustible flame spread rating of 6; less than other non-metallic panels.
UNITREX polycarbonate panels offer:
- Long-term weatherability.
- Virtually unbreakable strength.
- Lightweight for easy installation.
- Operating temperature range: -40 F to 212 F.
- Optical clarity.
- Impact resistance.
UNITREX 2.67- and 4.2-inch polycarbonate panels are clear as glass and more resistant to breakage. In addition, 2.67- and 4.2-inch panels offer more impact resistance compared to acrylic panels. The panels are half the weight of glass and thus easy to handle and install, durable, energy-efficient and easy to fabricate.
2.67- by 7/8-inch panels are available in clear and green translucent. 4.2- by 1-1/16-inch panels are available in clear, green translucent and opaque white. The panels are designed to match the profiles of metal sheets in the steel building industry.
