As the concept of energy conservation and environmental protection continues to gain traction, modern home living increasingly emphasizes the energy-efficient performance of doors and windows. High-quality, energy-saving doors and windows can help create a more comfortable living environment while also saving you significant expenses. So, what should we keep in mind when choosing energy-efficient doors and windows? Today, our editor will share a few handy tips—be sure to save this for future reference!
Procurement details for energy-efficient doors and windows:
1. Hardware Performance: Hardware components play a crucial role in the systematic design of energy-efficient doors and windows. The quality of these hardware parts directly influences the performance characteristics of the entire window or door system. It’s the hardware that enables the smooth, repeated opening and closing of windows and doors, making it essential to choose high-quality hardware. Moreover, the performance of the hardware directly impacts the overall manufacturing quality of the windows and doors. Whenever budget permits, we recommend opting for imported hardware components. However, if financial resources are limited, at least select top-tier, reputable domestic brands to ensure optimal energy efficiency of your windows and doors.
2. Thermal break aluminum profiles are a core component in energy-efficient window and door designs. The quality of the profile’s cross-sectional design directly determines the performance and overall quality of the windows and doors. The principle behind thermal break technology involves mechanically rolling a non-metallic insulating strip—typically made of nylon 66—into a seamless integration with two sections of aluminum alloy, creating a highly effective thermal barrier. During the cross-sectional design process, engineers primarily focus on balancing factors such as structural strength, rigidity, and stability, ensuring that, under the most cost-effective cross-sectional area, both the moment of inertia (I) and the section modulus (W) are maximized. Additionally, after embedding the insulating strip, filling the resulting cavity with supplementary insulation materials further enhances the profile’s ability to block convective heat transfer, significantly boosting its energy-saving performance.
3. Gap and Weatherproofing Design: To achieve superior water tightness, an equal-pressure sealant is designed based on the principle of equal pressure, while drainage channels are incorporated into the window frame to effectively direct rainwater away. For enhanced air tightness, sealing strips are installed to prevent air infiltration. Therefore, when selecting windows and doors, it’s crucial to carefully evaluate these design features.
4. The soundproofing performance of energy-efficient doors and windows is achieved through hollow glass, while their energy-saving properties are enabled by hollow glass's ability to block thermal radiation. Therefore, when selecting doors and windows, opt for hollow glass whenever possible—and if budget allows, consider LOW-E glass for even better energy efficiency.
5. The material for the sealing strip must be selected as EPDM rubber, which offers excellent advantages: it boasts superior weather resistance, outstanding heat resistance, and exceptional sealing performance. It’s also safe and reliable to use, with excellent water- and air-tightness properties.
