When the surface temperature of an object falls below the dewpoint temperature, condensation may occur, leading to the formation of water droplets. If condensation, vapor, black spots, or cracks appear inside hollow glass, it indicates potential quality issues related to desiccants or sealing techniques. However, if condensation occurs inside and dew flows down to the sill, it is considered a natural phenomenon, particularly pronounced with larger temperature differences between indoor and outdoor environments.


To prevent dew-related issues, it's crucial to select high-quality, air-tight aluminum window extrusions and doors. Here's how to choose them effectively:


1.Hollow Glass: Opt for premium-grade, tempered hollow glass systems like those offered by XINGFA. These glasses boast superior hardness, pressure resistance, and flatness. Injecting argon gas between the glass layers enhances soundproofing, creating a more comfortable indoor environment.


2.Rubber Strips: Ensure that the windows and doors are equipped with EPDM rubber strips, available in various types. These strips, when combined with proper assembly techniques including duct corners, resist heat, light, and oxygen, particularly ozone. They exhibit lower water absorption, offer insulation, abrasion resistance, and elasticity. Upon closure, these rubber strips effectively block raindrops, dew infiltration, and heat transfer.


3.Water Draining Design: Look for windows and doors with isobaric cavity designs that enhance waterproofing performance. Incorporating sinking water draining systems and side draining designs resolves issues related to track ponding, ensuring efficient water drainage.


By choosing aluminum window extrusions and doors equipped with these features, you can effectively prevent dew-related problems, ensuring a more comfortable and durable living environment.
