First and foremost, the primary function of sealing edges is to create a barrier that protects against environmental factors. In buildings, for instance, properly sealed edges around windows and doors prevent water infiltration and air leaks, thereby enhancing energy efficiency and reducing heating and cooling costs. Poorly sealed edges can lead to drafts, mold growth, and structural damage over time, which can be costly to repair. In addition, interior spaces benefit from sealed edges as they help maintain indoor air quality by limiting dust, allergens, and pollutants from entering.
