Superior Thermal Insulation & Energy Efficiency Icon

Superior Thermal Insulation & Energy Efficiency Key Feature

Utilizes a multi-chamber broken bridge aluminum profile combined with vertical isothermal design and Triple-Seal Technology, significantly reducing heat transfer between indoor and outdoor environments.

Equipped with high-performance Thermotech PA66 nylon insulation strips and optional LOW-E insulating glass (e.g., Low-E hollow/tempered laminated glass), which minimizes energy loss and reduces heating/cooling costs.

Supports China's "Dual Carbon" strategy by meeting the 3-star certification standards for green building materials (highest national rating).

Frequently Asked Questions

Everything you need to know about the Kirin K5N System Broken Bridge Inward Opening Window

Q What is a broken bridge aluminum window and how does the K5N series use this technology?

A broken bridge aluminum window uses a thermal barrier — typically a PA66 nylon insulation strip — inserted between the inner and outer aluminum profiles, effectively "breaking" the thermal bridge and preventing heat transfer. The K5N series enhances this with a multi-chamber profile design and vertical isothermal technology, delivering superior insulation performance compared to standard aluminum windows.

Q What is Triple-Seal Technology and why is it important for the K5N window?

Triple-Seal Technology refers to three independent sealing layers applied around the window sash, providing enhanced protection against air infiltration, water penetration, and noise. For the K5N series, this means better weatherproofing, improved acoustic insulation, and a more airtight seal that contributes directly to reduced energy consumption in both heating and cooling seasons.

Q What type of glass options are available for the K5N series?

The K5N series supports a range of high-performance glass configurations, including LOW-E hollow glass, tempered glass, and laminated glass combinations. LOW-E (Low Emissivity) coated glass is particularly recommended as it reflects infrared heat while allowing visible light to pass through, significantly reducing solar heat gain in summer and retaining warmth in winter.

Q What certifications does the K5N series hold for green building compliance?

The K5N series meets China's 3-star certification standards for green building materials, which is the highest national rating in China's green building evaluation system. This certification confirms that the product meets stringent requirements for energy efficiency, environmental sustainability, and material safety — making it fully aligned with China's "Dual Carbon" goals of carbon peaking and carbon neutrality.

Q What is the role of Thermotech PA66 nylon insulation strips in the K5N window system?

Thermotech PA66 nylon insulation strips are precision-engineered thermal barriers made from polyamide 66 (PA66) reinforced with glass fiber. They are inserted between the inner and outer aluminum profiles to interrupt thermal conductivity. In the K5N series, these high-performance strips offer excellent dimensional stability, resistance to UV aging, and long-term durability, ensuring the thermal performance of the window remains consistent over its entire lifespan.

Q Is the K5N inward opening window suitable for both residential and commercial projects?

Yes, the Kirin K5N System Broken Bridge Inward Opening Window is designed to be versatile and is well-suited for both residential and commercial applications. Its combination of advanced thermal insulation, triple-seal weatherproofing, and green building certification makes it an ideal choice for high-end apartments, villas, office buildings, and any project where energy efficiency and build quality are a priority.
