Highest Quality Standards
Our vinyl windows management team has over 100 years of experience in the vinyl window industry providing you insurance that all of our products are produced using the strictest quality standards.
Windows Made in Michigan
Paramount Improvements has been manufacturing premium vinyl windows since 1991. We offer a wide range of products including vinyl windows, doors, bay windows, garden windows, casement windows, awnings, windows for new constructions applications and shape windows.
Energy Star and NFRC Approved Windows
Each of the windows are welded using extrusions produced from virgin vinyl. Each product line has been tested and approved by energy star and NFRC. Who wouldn’t want an American made product with a 50 year warranty that looks good too?
