Glass doors are a unique type of door that differs from both solid and custom-shaped doors. Rather, they represent a special design form, where the main feature is determined by the glass itself. For instance, when using tempered transparent glass, the door allows light to pass through while maintaining privacy, whereas frosted glass provides a semi-transparent effect.
One of the key benefits of glass doors in winter is their ability to block wind while still letting in natural light, making them translucent rather than completely opaque. However, aside from this visual advantage, many people also care about how well the door retains heat.
According to experts, approximately 30% of heating or cooling energy is lost through doors, windows, and walls. Choosing double-glazed insulating glass during home renovation can significantly improve thermal efficiency compared to regular glass. This type of glass prevents heat transfer, helping maintain indoor comfort and reducing energy waste. The ideal energy-saving option today is double-insulated hollow coated glass, which features a 12 mm air gap, ensuring a stable indoor temperature.
In addition, during extreme weather conditions, rooms with double-glazed windows are more comfortable than those with single-glazed ones. For example, if the outside temperature is -10°C and the inside is 20°C, a single-glazed window may only reach a surface temperature of 1°C, creating a large temperature difference between the window and the human body. This can lead to discomfort as the body loses radiant heat when near the glass.
With double-glazed glass, the temperature difference is significantly reduced. Moreover, the installation of two layers of insulated glass creates a tighter seal between the wall and the window, effectively blocking noise and dust from outside. This not only improves sound insulation but also enhances the living environment, promoting better health for the occupants. As an added tip, using thick fabric curtains can further enhance the insulation effect.
When purchasing glass doors, consumers should be cautious and pay attention to several important factors:
1. Avoid buying cheap products without proper packaging. Ensure the product has a brand label, address, and certification. Products without packaging should be avoided. Tempered glass must have a CCC certification and clear branding.
2. Tap the glass gently with your knuckles. Tempered glass produces a crisper sound, while ordinary glass sounds duller.
3. Authentic tempered glass often shows a faint pattern when viewed closely.
By following these guidelines, you can ensure you're getting a high-quality, safe, and efficient glass door that meets your needs and enhances your home's comfort and aesthetics.
