Performance Manufacturing

A Legacy of Innovation and Sustainability

Proformance Manufacturing Inc. (PMI) was founded in 2008 by Mr. Gerald (Jerry) Beranek, fueled by a vision to create premium windows that combine unparalleled comfort, beauty, and sustainability. With over 20 years of industry expertise, Jerry recognized the potential of fiberglass to revolutionize window manufacturing, and thus PMI was born.

Exceptional Windows for Modern Homes and Businesses

We specialize in crafting exceptional windows using fiberglass, the ultimate material for windows. Fiberglass windows offer a unique combination of strength, insulation, and sustainability, making them ideal for both residential and commercial applications. Our product line includes:

• ECOSTAR Windows: Designed for exceptional energy efficiency and sustainability, boasting excellent thermal insulation and reduced heat transfer.
• ProStar Windows: Engineered for durability, featuring high impact resistance, warp resistance, and top-notch insulation.

Commitment to Sustainability and the Environment

Sustainability defines who we are. We prioritize environmentally-conscious manufacturing practices, utilizing materials sourced within a 70-mile radius of our Lone Rock, Wisconsin facility. This significantly reduces our environmental footprint. Additionally, our windows are manufactured with renewable materials and feature industry-leading energy efficiency, contributing to a greener future.

Exceptional Quality and Customer Satisfaction

At PMI, quality is our highest priority. We utilize advanced technologies and implement meticulous quality control measures to ensure every window exceeds expectations. Our commitment to excellence is evident in our comprehensive warranty and unwavering customer satisfaction record.
