We welcome you to stop by our facility and review our entire product line in our showroom.

In our showroom, we can easily show how the installation will be performed by our team or if you are doing it yourself, or another contractor. We would be happy in assisting you in choosing the right products for your project.

During your trip to our showroom, we will educate you on performance and quality of each product and assist you in finding the look that you desire. At the same time, this will give us an opportunity to show you why Kelly Window Systems Inc. is so easy to work with from start to finish.

We would be happy to set up an appointment for a free “in Home” demonstration with one of our sales specialist if this is more convenient for you.

Kelly Window Systems was founded in 1982 as a family owned and operated business. Our story began as a construction management group that was founded in 1959 by Pasquale Giugliano. Giugliano and his five sons Frank, Pat, Bill, Carl, and Angelo started and operated F&F Products, offering construction management, roofing, siding, and window installation. After years of installing windows on various jobs, Carl Giugliano formed Kelly Windows System, Inc. Carl noticed an unfortunate decline in the craftsmanship of the windows and doors F&F Products were installing for their clients from other manufacturers.

Carl did not want to be forced to use such poor craftsmanship and recognized a definite need to assure they were offering quality windows and doors. So in 1982 Carl decided it was time to design and make their own windows. This gave them full control over all aspects of the product and assured 100% customer satisfaction with every order.

Starting out in a 5, 000 Square foot building in 1982 has now blossomed into a now over 40,000 square foot of “State of the art” manufacturing facility. This allows for the quick and efficient production of standard and custom size windows and doors 6 days a week.

We take pride in producing premium aluminum and vinyl windows and doors, as well as high-performance glass packages. Headquartered in Farmingdale, Long Island. Kelly Window Systems, Inc has been servicing Long Island and the tri-state area for over 30 years.
