Is The Window Place USA an authorized vendor for government window film procurement?

Yes. The Window Place USA is a SAM.gov-registered vendor (CAGE Code: 52MH9, DUNS: 807327700) and an authorized distributor of Saint-Gobain SolarGard architectural window films. We accept GSA SmartPay and P-Cards for federal and municipal procurement of ASTM F1642-compliant Armorcoat blast mitigation films and solar control films.

Which window film is recommended for school safety and delayed intrusion?

For school safety applications, we recommend SolarGard Armorcoat Safety and Security Window Film in 8-Mil or 14-Mil thicknesses. These films are tested to delay forced entry, buying critical time for law enforcement response, and hold shattered glass together to minimize injury during impact events. Both the 8-Mil and 14-Mil products are certified to ASTM F1642 blast mitigation standards.

Does SolarGard Ecolux 70 Low-E qualify for the Federal Energy Tax Credit?

SolarGard Ecolux 70 Low-E window film may qualify for the 30% Federal Energy Efficiency Tax Credit (Section 25C, IRS Form 5695) under the Inflation Reduction Act for qualifying residential installations through December 31, 2032, subject to an annual cap of $1,200. Consult your tax advisor to confirm eligibility for your specific installation.

Does The Window Place USA ship window film to all 50 states?

Yes. The Window Place USA ships factory-sealed SolarGard master rolls via FedEx Ground and Freight to all 50 states. Orders placed before 2:00 PM EST are eligible for same-day dispatch. We do not offer overnight or expedited shipping options.

Year-Round Savings: How Low-E Window Films Benefit Your Home in Every Season

The Challenge of Multi-Season Climates

When most homeowners think of window film, they think of summer: blocking the blazing sun to keep the house cool. And while standard solar control films excel at this, they don't do much to help when the snow starts falling. In fact, standard reflective films can actually be a detriment in the winter by blocking the passive solar heat you want to enter your home.

If you live in a climate with both hot summers and freezing winters, the U.S. Department of Energy (DOE) points to a specific technology designed to handle both extremes: Low-Emissivity (Low-E) window film.

What is Low-E Window Film?

Low-E films are an advanced category of window attachments. The DOE explains that these films have specialized coatings that are "effective in reducing winter heat loss and increasing thermal comfort of occupants" [1].

How does it work? "Emissivity" refers to a material's ability to radiate heat. A low emissivity coating acts like a thermal mirror.

The Dual Action of Low-E Film	How It Works
Summer Cooling	Like standard films, Low-E films are "effective at reducing near IR solar radiation," rejecting the sun's heat to lower your air conditioning bills [1].
Winter Heating	In the winter, the Low-E coating reflects radiant heat (from your furnace or fireplace) back into the room, rather than letting it escape through the cold glass [1].

This dual-action performance makes Low-E films the ultimate year-round energy-saving retrofit for residential windows.

A Cost-Effective Alternative to New Windows

Historically, the only way to get the benefits of a Low-E coating was to purchase entirely new, factory-sealed windows—a massive expense.

Today, that technology is available as a retrofit. The DOE notes in its Window Types and Technologies guide that "although low-e coatings are usually applied during manufacturing, some are available for do-it-yourselfers" [2].

The financial case for retrofitting is compelling. The DOE states that these films "are inexpensive compared to total window replacements, last 10 to 15 years without peeling, save energy, reduce fabric fading, and increase comfort" [2]. By purchasing a supply-only roll of Low-E film, you can upgrade your existing single-pane or standard double-pane windows to near-modern efficiency standards for a fraction of the cost of replacement.

Frequently Asked Questions

What is the difference between solar film and Low-E film?
Standard solar film only blocks heat from coming in during the summer. Low-E film blocks heat in the summer, but also reflects your home's interior heat back into the room during the winter, providing year-round insulation [1].

Does the DOE recommend Low-E film?
Yes. The DOE notes that Low-E films are emerging as an energy-saving option that is effective in reducing winter heat loss and increasing thermal comfort [1].

Can I install Low-E film myself?
Yes. The DOE confirms that while low-e coatings are often applied during manufacturing, low-e films are available for do-it-yourself projects, making them a highly cost-effective retrofit [2].
