Our Vinyl Formula
Want quality windows that fit your budget? Try our vinyl windows. Vinyl frames are easy to clean, keep their shape and color through hot summers and cold winters, resist moisture, and never need painting or staining. You could even save money on energy bills thanks to vinyl’s natural insulation.
Our vinyl formula stands the test of time, thanks to premium ingredients and exacting manufacturing. We extrude our own frame material, which meets the strict AAMA requirements for structural integrity. That means you get strong, long-lasting windows and doors that look good for years to come.
Complete Quality Control
Your windows are faced with rain, wind, and temperature changes every day. That’s why we have a comprehensive quality control process to make sure corner welds stay strong and glass stays firmly in place. Each design goes through tough tests for strength, water leaks, air sealing, forced entry, and more.
While our inspection teams perform quality audit checks every hour of every day on every line, we also test MI windows and patio doors to meet AAMA Gold Label Certification on performance standards. That way, you know you’re getting top-notch reliability from your products.
