Doors and windows are an essential part of home life—after all, quality ones not only shield us from wind and rain but also help conserve energy, creating a warm and cozy atmosphere that feels like home. Especially as modern living standards continue to rise, people’s expectations for doors and windows have grown significantly, leading to increasingly advanced features and functionalities. To ensure consumers enjoy a more comfortable environment, many leading brands now opt for double- or even multi-layered insulated glass. Yet, surprisingly, many customers still aren’t fully aware of the reasons behind this choice. That’s exactly what we’ll explain to you today!
1. What is hollow glass?
Double-glazed glass units consist of two or more layers of flat glass, with the edges sealed together using a high-strength, highly air-tight composite adhesive. This process bonds the glass panes—along with sealing and spacer bars—to form an airtight unit. The space between the glass layers is then filled with dry gas, while desiccants are placed inside the frame to ensure optimal dryness of the air trapped between the panes.
2. What are the benefits of installing hollow glass?
First, it provides excellent insulation.
Thermal insulation is a two-way process: it prevents cold or hot air from entering from the outside, and it also stops indoor cold or hot air from escaping. This ensures that whether you're heating your home in winter or using air conditioning in summer, energy isn't wasted due to poor window insulation performance.
Second, excellent sound insulation.
Double- or multi-layer insulated glass offers significantly better soundproofing performance than single-layer glass—this is obvious. For modern living, this feature is incredibly important. High-quality insulated glass helps maintain a peaceful indoor environment, promoting rest and ensuring privacy, especially for those living near busy streets or in noisy residential areas where noise levels can be particularly high.
In summary, if you have high standards for your quality of life and can afford it, we recommend giving more consideration to double- or multi-layered insulated glass when choosing doors and windows. Of course, opting for LOW-E glass would be even better, as it also provides protection against radiation.
