Ecolux 70 Low-E — Dual-Climate Energy Performance for Federal Facilities
Solar Gard® Ecolux 70 Low-E is an advanced low-emissivity window film engineered for year-round energy performance in government buildings, military installations, and institutional facilities. By combining solar heat rejection with radiant heat retention, Ecolux 70 addresses both cooling and heating loads — directly supporting Executive Order 14057 decarbonization mandates and federal net-zero emissions goals.

Federal Facility Applications
- Federal Office Buildings: Reduces HVAC energy consumption in GSA-managed facilities while maintaining daylighting standards
- Military Installations: Upgrades single-pane glazing in barracks, administrative buildings, and medical centers
- VA Hospitals & Clinics: Improves patient comfort, reduces glare on medical displays, and lowers operating costs
- Courthouses & Judicial Facilities: Preserves natural light in courtrooms while reducing solar gain
- Historic Federal Buildings: Approved for historic preservation projects — enhances energy performance without altering window appearance
- Schools & Universities: Reduces classroom overheating while maintaining visual connection to outdoors
EO 14057 Compliance Support
Ecolux 70 Low-E directly supports the federal government's commitment to achieving net-zero emissions by 2050. Retrofitting existing glazing with low-emissivity film is recognized as a cost-effective decarbonization strategy that avoids full window replacement, reduces embodied carbon, and delivers measurable energy savings within the first year of installation.

Frequently Asked Questions — Ecolux 70
Yes. The Window Place USA sells Solar Gard window film by the full factory-sealed 100-foot master roll only. We do not sell partial rolls, cut pieces, or samples. Each roll ships directly from our warehouse via FedEx.
This is a material-only purchase. The Window Place USA is a wholesale distributor — we supply the film, not installation labor. Most of our customers are professional installers, contractors, facility managers, and procurement officers who arrange their own installation.
Yes. We ship to all 50 states via FedEx Ground. Government agencies, schools, and commercial buyers can use P-Card, purchase orders, or standard payment methods. We are SAM.gov registered (CAGE: 52MH9) for federal procurement.
Low-E (low-emissivity) window film has a special coating that reflects radiant heat back toward its source. In winter, it helps retain interior heat by reflecting it back into the room. In summer, it rejects incoming solar heat. This dual-season performance is why it's called a "dual-climate" film.
In summer, Ecolux rejects up to 53% of total solar energy to reduce cooling loads. In winter, its low-emissivity coating (0.15 emissivity) reflects interior radiant heat back into the building, reducing heat loss through windows by up to 30%. This year-round performance can significantly reduce HVAC costs.
Yes. Ecolux Low-E film can reduce cooling costs by up to 40% in summer and heating costs by up to 30% in winter, depending on climate zone, glass type, and building orientation. It's one of the most cost-effective energy-efficiency retrofits available for existing glazing.
Absolutely. Ecolux is designed for commercial, government, institutional, and large-scale residential applications. It supports Executive Order 14057 net-zero goals, qualifies for LEED v4.1 credits, and is NFRC-certified. It's also eligible for the 30% federal energy-efficiency tax credit on qualifying projects.
Dual-climate performance means the film provides meaningful energy benefits in both hot and cold seasons — not just summer cooling. Ecolux achieves this through its combination of solar heat rejection (summer) and low-emissivity radiant heat retention (winter), making it effective in virtually any U.S. climate zone.
Federal facility managers, energy consultants, commercial building owners, sustainability officers, and professional installers. Ecolux is frequently specified in government energy-efficiency retrofits, LEED projects, and historic preservation upgrades where window replacement isn't feasible.
Standard solar control films (like TrueVue) primarily reject summer heat and glare. Ecolux adds winter insulation performance through its Low-E coating, making it a true year-round energy solution. If your building has significant heating costs or is in a mixed climate, Ecolux may deliver better overall ROI. Learn more about dual-climate films here.
