Why is the installation of weather seals critical in glazing?

The installation of weather seals is critical in glazing primarily because it ensures energy efficiency and prevents leaks. Effective weather seals play a vital role in establishing a barrier against air and water infiltration. When properly installed, these seals help maintain the internal environment of a building by minimizing drafts, reducing heat loss in colder months, and preventing heat gain during warmer months. This not only contributes to a comfortable indoor environment but also enhances the overall energy efficiency of the structure, leading to lower heating and cooling costs.

Additionally, weather seals protect the integrity of the building elements by preventing moisture ingress, which can lead to damaging effects such as mold, structural deterioration, and enhanced wear on building materials. Thus, the critical function of weather seals directly impacts the longevity of the glazing and the overall performance of the building envelope.
