With decades of experience in window and door repair across NYC, we know the right products paired with expert craftsmanship make all the difference.
So, what makes the OSI QUAD® MAX system superior? Let’s break it down.
The Three-Part OSI QUAD® MAX System
A high-quality installation is more than just fitting a window or door into place. True performance comes from how the product is sealed, insulated, and protected. The OSI QUAD® MAX system has three key components—each one engineered for durability, energy efficiency, and superior protection against New York’s toughest weather conditions.
1. Butyl Flashing Tape: A Critical First Layer of Protection
Flashing tape may not be visible once the job is done, but it plays a vital role in NYC window installations. When properly applied around a window or door opening, OSI Butyl Flashing Tape creates a strong barrier that prevents water intrusion.
Why is this important? Water infiltration can lead to mold, mildew, rot, and even structural damage over time. In the city’s older buildings—especially those in historic districts—this added protection is critical. Think of flashing tape as your home’s first line of defense. With WindowFix’s certified expertise and OSI’s superior materials, you get long-term protection you can trust.
2. Sealant: OSI QUAD® MAX for Lasting Flexibility and Adhesion
No installation is complete without a reliable seal. That’s why WindowFix uses OSI QUAD® MAX sealant, a next-generation solution that combines unmatched adhesion and flexibility. Unlike lower-quality sealants, QUAD® MAX won’t crack, shrink, or fail—even after years of seasonal expansion and contraction common in New York’s climate.
Available in over 300 colors, this sealant also delivers a seamless, polished finish that blends with any home exterior. For homeowners seeking energy-efficient window replacement in NYC, QUAD® MAX ensures airtight, watertight, and long-lasting results that enhance both comfort and curb appeal.
3. QUAD® FOAM: Insulation That Performs Under Pressure
Finally, OSI QUAD® FOAM ensures your installation is as energy-efficient as it is durable. With its closed-cell structure, this insulation creates a dependable barrier against air and moisture, keeping drafts out and heating and cooling costs down.
Designed with strength and flexibility, QUAD® FOAM adapts to the city’s seasonal temperature swings without compromising performance. It’s the ideal choice for homeowners who want NYC window installations that improve comfort while lowering energy bills year-round.
