Precision you can feel. Performance you can trust.
At TQC Windows & Doors, engineering is where craft meets numbers. Led by founder and windows R&D contributor Sunny Saini, we turn design intent into window and door systems that are beautiful, buildable, and built to last. From early calculations to on-site verification, we obsess over the details—so your project runs smoothly from concept to installation.
PRECISION, COMFORT, CODE-ALIGNED.
WE ENGINEER WINDOWS AND DOORS THAT ARE BEAUTIFUL, BUILDABLE, AND BUILT TO LAST. STRUCTURAL, THERMAL, AND WATER-MANAGEMENT DETAILS ARE RESOLVED UPFRONT—SO INSTALLS GO SMOOTHLY AND PERFORMANCE IS PROVEN IN THE FIELD.
