What are the main factors affecting the K-value of doors and windows? What efforts has Joyfident Doors and Windows made to reduce the K-value of doors and windows?

I.Core factors affecting the K-value of Doors And Windows: thermal conductivity of profiles, glass configuration (number of layers/air cavity structure/Low-E coating), and sealing performance.

Profiles: Thermal break aluminum (with nylon heat-insulating strips) has weaker thermal conductivity than ordinary aluminum profiles; plastic-steel and wooden profiles have even lower K-values.

Glass: Triple-glazed hollow glass with Low-E coating and inert gas filling has several times better insulation than single-pane glass.

Sealing: Multi-seal gaskets and cavity sealing design reduce heat loss caused by air infiltration.

II.JoyfidentDoors and Windows' Efforts to Reduce K Value:

1.Optimized profile structure: Its 126 series premium aluminum-clad wooden window incorporates graphite polyethylene sandwiched between precious wood, improving insulation by 30% compared to traditional Wooden Windows; the outer aluminum structure is optimized with increased thickness to enhance insulation and structural stability.

2.Upgrade glass configuration: All models are equipped with triple glass and two cavities, 4SG warm edge spacers, LOW-E coating, and filled with argon gas. This configuration can significantly reduce heat transfer through the glass, improve thermal insulation performance, and lower the K value.

3.Strengthened Sealing Technology: Featuring a four-seal design and multiple locking points, combined with seamless aluminum welding process, it reduces air infiltration through window and door gaps, thereby lowering heat loss caused by thermal convection from the root cause.

4.Control production and material selection: Introduce a complete set of energy-saving wooden window production lines from Germany, select imported top-grade raw materials, and further enhance the stability of the window's thermal insulation performance in the production process through nearly thirty related patent technologies, helping to reduce the overall window K-value.
