Cost-Effective Retrofitting Solutions with EXTECH Polycarbonate Systems
April 24, 2024
Retrofitting your building with EXTECH's polycarbonate systems can be a game-changer. EXTECH/Exterior Technologies, Inc. leads the charge in enhancing the lifespan of your building's exterior envelope while slashing long-term maintenance and replacement expenses. Their expertise ensures that these solutions aren't just about cost savings; they significantly boost energy efficiency too, thanks to their stellar thermal insulation properties that curtail heat transfer through walls and roofs. By opting for EXTECH's polycarbonate systems, you're not just investing in your building's future but also in a greener, more sustainable tomorrow.
Making the Switch: Overglazing or Total System Replacement?
When transitioning from traditional systems to EXTECH's polycarbonate ones, it's crucial to note that the rabbets of traditional framing systems may not align seamlessly. EXTECH's solutions require controlled pressure gaskets, a low-friction treatment, and a framing system designed to accommodate thermal movements and facilitate water drainage for optimal weather sealing.
You have options, guided by EXTECH's expertise. Entire system replacement with polycarbonate systems is one route, leveraging EXTECH's innovative solutions. Sometimes, existing framing can serve as the support structure, while in other cases, a complete overhaul might be necessary. Take, for instance, the MTA skylight retrofit in the Bronx, NY, where EXTECH's solutions proved indispensable. The original skylights were emitting excessive solar energy and glare, necessitating a more sustainable fix than merely painting them black. Replacement polycarbonate skylights from EXTECH, featuring 25mm opal cellular polycarbonate, were the answer. They achieved 27% light transmission and a .37 solar heat gain coefficient, providing ample daylight for maintenance crews while reducing reliance on overhead lighting.
Overglazing: A Smart, Cost-Effective Solution
Overglazing with EXTECH's polycarbonate systems presents a cost-effective means of boosting energy efficiency and aesthetics in existing buildings. This approach involves adding a layer of EXTECH's polycarbonate panels over existing windows or glazing to enhance thermal performance, natural light transmission, and overall durability.
EXTECH's polycarbonate skylights and walls are particularly well-suited for overglazing due to their lightweight nature, requiring minimal additional support. In a Los Angeles project for a Boys & Girls Club, EXTECH's expertise shone through. Adding a cellular polycarbonate overglazing system from EXTECH increased the overall weight by just about 0.05 kPa (1 psf), a negligible impact on the steel support structure below. Moreover, labor costs were kept in check as the original framing and glazing system remained untouched.
Testing & Warranty
EXTECH's commitment to quality shines through in their testing and warranty standards. Polycarbonate glazing from EXTECH typically comes with a 10-year warranty covering colorfastness, hail damage, and light transmission loss. The framing finish is also backed by a 10-year warranty, with comprehensive manufacturer warranties ensuring protection against deterioration and leakage.
EXTECH's systems undergo rigorous testing, conforming to standards like AAMA E 283 for air infiltration, AAMA E 330 for structural strength, and ASTM D-2244 for color change, among others. Additional tests, such as ASTM D-635 and ASTM E-84, assess resistance to fire and smoke generation, ensuring the safety and reliability of EXTECH's polycarbonate systems.
Unlocking the Benefits
Retrofitting buildings with EXTECH's polycarbonate systems yields a myriad of benefits, from enhanced energy efficiency and natural light to improved durability, versatility, and substantial cost savings. As you weigh your retrofitting options, remember to evaluate your building's specific needs and desired outcomes to determine the most suitable solution.
