CUYAHOGA FALLS, Ohio — Alside, a leading manufacturer and distributor of exterior building products, launches ClimaTech PriME, a family of high-performance insulated glass packages to its replacement window product portfolio. ENERGY STAR has recognized it as meeting the criteria for the Most Efficient designation on select Alside vinyl windows and patio doors. This achievement not only underscores Alside’s commitment to offering energy-efficient products, but it also provides homeowners the opportunity to possibly benefit from valuable federal tax credits*.

“With ClimaTech PriME high-performance insulated glass packages, homeowners can combine energy savings, environmental responsibility and financial benefits,” said Adam Copel, Windows Business Director for Alside. “By making the choice to upgrade their windows with this innovative glass package, homeowners are investing in a more sustainable and energy-efficient future.”

Now offered on Mezzo and Fairfield 80 Series windows, homeowners can significantly reduce their home’s energy consumption and lower their utility bills while potentially qualifying for valuable tax credits. ClimaTech PriME meets the energy-efficiency performance requirements for all four climate zones of the country.

Survey Says

Alside recently commissioned a national survey**, conducted online by The Harris Poll®, to learn valuable insights into the window purchasing experience and found enhancing energy efficiency was the top reason house/apartment/condo owners would consider replacing windows. With ClimaTech PriME, homeowners have a new product option to help reduce energy costs and possibly be eligible for tax credits as part of the government’s efforts to incentivize energy-efficient upgrades in homes under the Inflation Reduction Act of 2022. Under the program, most homeowners are eligible to claim 30% of window product costs, up to $600 per year, provided the replacement window performance meets ENERGY STAR Most Efficient requirements. Additionally, homeowners can utilize ClimaTech PriME technology on sliding glass doors to potentially earn incremental tax credits of $250 per door (up to $500 per year).

A Closer Look

According to the National Fenestration Rating Council, the average American household spends $1,500 to $2,500 annually on energy bills, and up to 45% of that cost is for heating and cooling, depending on climate zone. Choosing high-performance windows can help save homeowners money. ClimaTech PriME features a hermetically sealed triple-pane insulated glass unit that provides a powerful energy-efficient design with three panes of glass, three surfaces of Low-E (low-emissivity) technology, two spaces of argon gas fill and two warm-edge spacers.

Cost-Advantage: Argon Gas —  ClimaTech PriME uses argon gas between the panes of glass—a more cost-effective solution compared to krypton gas typically used to achieve ENERGY STAR Most Efficient certification. The lower relative cost of ClimaTech PriME may help provide a higher return on investment for homeowners.
