Glass strip sealing or caulking, which one is better? Glass strip sealing is relatively more standardized and weather-resistant compared to caulking. It is not limited by the installation skills of the installer.
As for visible hinges and concealed hinges, how to choose? Visible hinges have strong load-bearing capacity and can open up to 180 degrees, but they may have relatively poor sealing. Concealed hinges, on the other hand, offer aesthetic appeal and good sealing, making them a common choice for contemporary window systems.
Does thicker wall thickness mean better performance for doors and windows? The performance of doors and windows is not directly related to the profile wall thickness. It is more closely related to factors such as glass, hardware, sealing strips, and installation.
What does 75/85/105 for doors and windows refer to? It indicates the series of doors and windows, specifically the frame width of 75mm. A larger series number does not necessarily mean better performance.
What is the difference between a single window and an integrated window with a screen? A single window has better sealing and insulation performance, while an integrated window with a screen is more aesthetically pleasing.
How to choose between inward-opening and outward-opening windows? Inward-opening windows are more common in the northern regions due to better insulation and sealing, while in the southern regions, outward-opening windows are recommended for superior waterproofing.
What does 5+18A+5 mean? It indicates the combination of glass layers. In this case, 5 refers to a single glass thickness of 5mm, A denotes air, and 18A represents an air layer thickness of 18mm.
What is double glass with one chamber/three glasses with two chambers? 5+18A+5 refers to double glass with one chamber, while 5+12A+5+12A+5 refers to triple glass with two chambers, providing better insulation.
What is low-e glass? It is a coated glass that effectively blocks mid- to far-infrared rays, reducing indoor heat radiation.
What is laminated glass? Laminated glass effectively isolates mid- to low-frequency noise and blocks ultraviolet rays.
What to consider when choosing glass for doors and windows? Pay attention to low-emissivity (low-e) coatings, and upgrading from low-e to high-transmittance low-e may incur additional charges. Additional fees may be required for glass exceeding 2.5 square meters, and extra costs may apply for transporting oversized glass.
What glass brands are there? Original glass manufacturers include Xinyi, Nangang, Beigang, Taibao, Jinjing, Zhongbo, Luobo, etc. Processed glass factories include Shandong Penghao, Shandong Xingguan, Luoyang Landi, Tianjin Wizdom, etc.
What is PA66-GF25 insulating strip? PA66 refers to nylon material, and GF25 indicates it contains 25% glass fiber.
What is a multi-chamber insulating strip? Multi-chamber insulating strips, such as I-shaped, C-shaped, T-shaped, and multi-chamber types, provide better stability and insulation compared to other types.
In theory, a wider insulating strip provides better thermal insulation, but some brands may choose very wide insulating strips to save aluminum, affecting the load-bearing capacity of the profile.
