YOU'RE PART OF THE FAMILY WITH INTERSTATE

OUR HISTORY

Interstate Building Materials has a long, rich history. In 1938, Joseph Pupa Sr. founded Interstate Home Improvement Company in Wilkes-Barre, Pennsylvania, and began providing quality building materials to Northeast Pennsylvania. He believed that employee values should be the focus for building his company’s reputation. With the strength built on those values, he passed the torch to his son, Joseph Pupa, Jr. Now, three generations have grown up in the business, with Joseph Pupa III leading our company since 2000.

BREAKING THE MOLD

In 1984, Interstate expanded its product line by manufacturing vinyl windows and doors. We are the first company in the United States to introduce an all vinyl single hung window to the new construction market. In 1985, an affiliated company named Interstate Window & Door Company was fully incorporated. Research and development begun to develop a fully integrated, all welded double hung vinyl window system specifically designed for the new construction market.

Things began to really pick up for the company in 1986. Not only did Interstate break ground on a 36,000-square-foot manufacturing plant in Pittston, Pennsylvania, but we had donated our vinyl windows to the Statue of Liberty restoration project. To this day, our vinyl windows are still standing in the national monument’s pavilion.

THE FUTURE IS OURS

In 1991, Interstate Window & Door Company was awarded for outstanding performance by the Vinyl Window & Door Institute. We continually stay above the curve in manufacturing technology to make sure our products are the most energy efficient and highest quality windows on the market today. Today, Interstate offers roofing, siding, kitchen cabinets, and energy efficient Vinyl and CompositWood windows. Interstate truly is a proven company that sells products engineered to last.

OUR AFFILIATIONS

NFRC is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Our goal is to provide fair, accurate, and reliable energy performance ratings so that:

  • Architects, builders, code officials, contractors, homeowners, and others can compare different products and make informed product choices.
  • Building officials, state government employees, and others involved in code development and enforcement can determine if products meet local codes
  • Government- and utility-run energy efficiency programs can establish performance requirements and standards.
  • Manufacturers have a fair and level playing field to compare products and an accurate method of showing the energy benefits of new designs or technology.

ENERGY STAR was created to help consumers easily identify products, homes, and building that save energy and money, and help protect the environment. As the government-backed, trusted symbol for energy efficiency, the ENERGY STAR label identifies highly efficient products and designates superior energy performance in homes and buildings. ENERGY STAR qualified windows today are, on average, twice as efficient as the average window made 10 years ago and can help reduce your energy bills significantly.

The American Architectural Manufacturers Association is the source of performance standards, product certification and education programs for the fenestration industry.

Products that are recognized as the Most Efficient of ENERGY STAR in 2017 meets rigorous energy efficiency performance levels set in the US. Our CompositWood windows have been awarded the ENERGY STAR Most Efficient mark for 2017.

Third party inspection and certification programs what enable window, door, and skylight manufacturers to demonstrate compliance with the requirements of building codes, the ENERGY STAR® Windows Program and other utility/tax rebate incentive programs.

ENERGY EFFICIENCY

Our products and processes emphasize energy savings – and that means we consume less energy to minimize the CO2 released into our environment.

Our buildings save energy by utilizing in-floor radiant heating during off-peak energy hours and by using motion controlled lighting.

Our processes conserve resources – like filtering and reusing glass wash water for glass rinsing, and recycling our vinyl and glass scrap created during the fabrication process. And of course, we have a recycling program for metals, cardboard and paper.

Interstate windows have been designated as “Envirosealed” windows through the use of the Duralite Spacer System technology, which saves energy, saves money and helps to save the environment.
