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.
Energy Efficiency & Passive House Standards
UPVC material is energy efficient and is a good choice for passive houses. The insulation of UPVC doors and Windows is superior: 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, it maintains a comfortable internal environment even in extreme cold conditions.
The sound insulation is equally impressive due to a carefully designed structure with tight joints, effectively blocking external noise.
Multi-Cavity Engineering
UPVC Windows are categorized into different series based on frame depth, including 50, 60, 70, and 88 series. We primarily utilize high-standard 70 and 88 series for enhanced performance.
The profile design features two-cavity, three-cavity, or multi-cavity structures. Increasing the number of cavities directly improves insulation and sound reduction. Furthermore, the cavity with lining steel is reinforced to improve the strength and stability of the units.
Semi-Automatic PET Bottle Blowing Machine technology and moulding equipment ensure that high-quality plastic containers and components are produced with precision for various industrial applications.

Professional Manufacturing & Passive House Concept
As a professional windows and doors manufacturer, our products include Thermal break aluminum windows doors, wood windows doors and passive house windows doors. Our main market coverage includes America, Canada, Australia and New Zealand, with products developed specifically to meet local standards and installation methods.
Passive house is a building standard that is truly energy efficient, comfortable, affordable and ecological. A Passive House window can reduce heat losses by more than 70% compared to existing double glazed windows. "Affordable Luxury" guides us to bring comfortable, quiet, and luxury life to more families.
Frequently Asked Questions
Q1: What is the thermal insulation performance of the K70 series?A1: 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 types, providing superior thermal efficiency.
Q2: Are your UPVC windows certified for international markets?A2: Yes, our products are certified by ENERGY STAR and CSA, and are designed to meet the rigorous standards of the USA, Canada, Australia, and New Zealand.
Q3: Why is UPVC better than aluminum for insulation?A3: UPVC has significantly lower thermal conductivity. The heat insulation effect of plastic composite profiles is approximately 1250 times better than that of standard aluminum.
Q4: What is a "Passive House" window?A4: It is a high-standard energy-efficient window that can reduce heat loss by more than 70% compared to traditional double-glazed windows, contributing to an ecological and cost-effective home.
Q5: How does the multi-cavity structure benefit the window?A5: Multi-cavity designs (2, 3, or more) enhance both thermal and sound insulation. Larger cavities with lining steel also significantly improve the structural strength and stability.
Q6: What frame series do you offer?A6: We offer various depths including 50, 60, 70, and 88 series to meet different architectural and insulation requirements.
