Lindsay Windows
Pinnacle Windows
Your windows affect your comfort, your energy bills, and the value of your home. Pinnacle, the top of the Lindsay Window line, combines refined styling with strong performance and fits nearly any home style.
Pinnacle windows are built to meet ENERGY STAR 2016 standards, with options that meet or exceed requirements in every ENERGY STAR region. They help lower energy use, ease the load on your heating and cooling systems, and keep your home more comfortable year-round. A warm edge spacer reduces condensation, frost, and mold growth, while argon or krypton gas retention helps them perform in extreme weather.
Pinnacle windows are made and assembled in the USA, using a significant share of American-sourced materials. Patented SecureEZ hardware hides the tilt latches for a cleaner, high-end look and lets the sash tilt in for easy cleaning. Lindsay has been building windows since 1947, and every Pinnacle is backed by a non-prorated, transferable lifetime limited warranty that covers the window for as long as you own your home.

How it all started
Lindsay Windows Journey
Lindsay Window & Door was founded in 1947 and has remained a privately held, family-owned company for more than 70 years. Headquartered in North Mankato, Minnesota, Lindsay specializes in custom vinyl replacement and new construction windows, as well as patio doors. Over the years, the company has grown from a small regional operation into a multi-state manufacturer with production facilities in Minnesota, Missouri, California, Georgia, Illinois, Texas, and Washington. Its lineup now includes five window series: Pinnacle, ClimateSmart, CrownView, SunView, and Healthy, giving homeowners options for different budgets, styles, and energy needs. Throughout its growth, Lindsay has stayed focused on its original mission of using quality materials, advanced manufacturing equipment, and proven processes to build windows that last.
As a trusted Lindsay installer, GL Construction LLC brings that same commitment to Wisconsin homeowners. Whether you choose the premium Pinnacle or the more affordable ClimateSmart, you get American-made windows backed by decades of experience, installed by a team that stands behind its work.
