Premium uPVC Windows and Doors: S70 and S80 Systems for Energy-Efficient Homes

Eco Windows USA offers two exceptional uPVC window systems designed to maximize energy savings while delivering superior performance for residential properties. The S70 and S80 systems represent the pinnacle of European window engineering adapted for American homes.

S70: Five-Chamber Thermal Excellence

The S70 system features a 5-chamber design that provides outstanding thermal insulation. This system excels in noise reduction and wind resistance, making it ideal for homes requiring superior acoustic performance. The S70’s narrow frame profiles maintain elegant aesthetics without compromising functionality, while its multipoint locking system ensures exceptional security. With RC2-tested burglar resistance and three sealing levels, homeowners enjoy both protection and peace of mind.

S80: Seven-Chamber Passive House Profile

For those pursuing zero-energy certification, the S80 Passive House system delivers unmatched thermal performance. Its revolutionary patented plastic and aluminum construction eliminates traditional steel reinforcements-the most common thermal weak point in conventional windows. The seven enclosed air chambers create unprecedented insulation efficiency. The S80 carries official Passive House certification from the ift Rosenheim testing laboratory, making it the preferred choice for net-zero and ultra-efficient residential projects. Its three-level sealing system provides superior defense against wind, rain, and thermal loss.

Key Benefits of Both Systems

Both systems feature excellent wind/water ratings, multipoint locking mechanisms, and optional moise reduction glass up to 42 OITC. Whether selecting the S70 for balanced performance or the S80 for passive house certification, Eco Windows USA provides the energy-efficient solutions that modern homeowners demand. Professional installation services ensure optimal performance across Connecticut, New York, and surrounding regions.
