High-Performance Energy Efficiency
Discover the K70 UPVC Window, a testament to modern engineering and energy efficiency. Our window is designed with a U-Factor of 0.88 W/m²·K for fixed installations and 1.1 W/m²·K for casement, ensuring superior thermal insulation, an air leakage rate of 0.07 cfm/ft², ensuring excellent sealing and energy conservation.
Certified by ENERGY STAR and CSA, our K70 UPVC Window is a reliable choice for both residential and commercial applications. It's not just a window; it's a smart investment in your home's comfort and energy savings. Experience the difference with our high-performance K70 UPVC Window.
Why Choose UPVC for Passive Houses?
UPVC material is energy efficient and is a good choice for passive houses. The insulation of UPVC doors and Windows is good: the plastic thermal conductivity of aluminum-plastic composite profiles is low, the heat insulation effect is 1250 times better than that of aluminum, coupled with good air tightness, even though it's tens of degrees below zero outside in cold areas, it's a different world inside.
The sound insulation of UPVC doors and Windows is good, its structure is carefully designed the joints are tight.
Professional Series & Multi-Cavity Design
UPVC Windows are named in different series according to different depths of frame in the market, such as 50 series, 60 series, 70 series; we use 70 series, 88 series.
The design of the profile is two-cavity, three-cavity or multi-cavity structure, and the more the cavities, the better the insulation and sound insulation effect of the profile. In addition, the cavity with lining steel is larger than the others which can improve the strength and stability of doors and Windows.

About Our Expertise
We are a professional windows and doors manufacturer. The products include Thermal break aluminum windows doors, wood windows doors and passive house windows doors. Our main market is America, Canada, Australia and New Zealand, and we have developed related products due to the local windows standard and installation methods. The created new models were all tested as per the four countries’ standard and achieved very high level standard. We also welcome clients from Europe and other countries.
Passive house is a building standard that is truly energy efficient, comfortable, affordable and ecological at the same time. It’s a construction concept that can be applied by anyone and that has stood the test of practice.
A Passive House window for example can reduce heat losses by more than 70 % compared to existing double glazed windows. Passive House buildings not only save money over the long term, but are surprisingly affordable to begin with. “Affordable Luxury” is guiding us to bring comfortable, quiet and luxury life to more and more families.
Frequently Asked Questions
Q: What is the energy efficiency rating of the K70 UPVC Window?
A: The K70 UPVC Window features a U-Factor of 0.88 W/m²·K for fixed installations and 1.1 W/m²·K for casement, providing superior thermal insulation.
Q: Are these windows certified for the international market?
A: Yes, our K70 UPVC Windows are ENERGY STAR and CSA certified, meeting high-level standards for North America and other regions.
Q: Why is the multi-cavity design important?
A: The multi-cavity structure (two, three, or more) enhances insulation and soundproofing. Cavities with steel lining also improve the overall strength and stability of the window.
Q: How does UPVC compare to aluminum for thermal insulation?
A: UPVC has significantly lower thermal conductivity. The heat insulation effect of plastic in composite profiles can be up to 1250 times better than pure aluminum.
Q: What window series do you offer?
A: While various series exist based on frame depth (50, 60, etc.), we primarily focus on high-performance 70 series and 88 series profiles.
Q: Can these windows be used in Passive House constructions?
A: Absolutely. Our Passive House windows can reduce heat loss by more than 70% compared to traditional double-glazed windows, making them ideal for energy-efficient building standards.
