Experiencing chilly drafts indoors on a windy day is a familiar occurrence across many regions in China. Insufficiently sealed house windows can leave occupants feeling as cold indoors as they would be outside.

1.Ensuring a Warm Interior:

Achieving warmth indoors while keeping cold drafts at bay relies heavily on the air-tightness of windows. The durability and design of rubber sealing strips play a pivotal role in enhancing air-tightness. Upgrading to softer rubber strips can significantly improve air-sealing properties. For sliding doors or windows, opting for quality brushes is essential to prevent dust and dirt infiltration through gaps.

Product Hardness: The material quality of windows also affects their resistance to wind and heat leakage. Products with low hardness and wind pressure resistance are prone to deformation over time, compromising air-tightness. Choosing reputable brands with advanced manufacturing facilities and adherence to ISO9001 quality standards ensures windows and doors with excellent air-tightness, water-proofing, noise-proofing, and wind pressure performance.

Metal Hardware: Strong and durable metal accessories are crucial for withstanding strong winds and preventing deformation. Lock points should be evenly distributed and parallel, with top and bottom lock points angled appropriately to ensure air-tightness. Strict assembly processes are vital to prevent leaks, while minimizing gaps between walls and windows is essential to prevent dust, dirt, and rainwater leakage.

2.Maintenance and Checks:

Regular maintenance and checks are necessary to ensure continued air-tightness. A simple self-check procedure involves lighting a candle or cigarette near the window frames. If the smoke rises straight up, it indicates superior air-tightness. However, if the smoke wavers or twists, it suggests inferior air-tightness.

DIY Solutions: Homeowners can improve air-tightness by purchasing window plastic seals to fill any leaks. Additionally, gaps between frames and walls can be filled with concrete or Styrofoam. While concrete is cost-effective and durable, it may not fully seal gaps and can be affected by thermal expansion. On the other hand, Styrofoam is soft, elastic, and unaffected by thermal changes, providing reliable air-tightness and insulation.

Addressing Leaks: Leaks between frames and walls may occur due to rushed construction or aging buildings. In such cases, homeowners should enlist specialists or builders to fill gaps and perform maintenance to ensure long-term air-tightness and insulation, especially before hazardous weather conditions.
