A barrier installed along the vertical edges of a garage door opening works to prevent the ingress of elements such as water, wind, dust, and pests. Typically made of flexible materials like vinyl, rubber, or foam, these barriers conform to the door’s movement while maintaining a tight seal against the frame. Various profiles and sizes exist to accommodate different door types and gap dimensions.
Effective sealing significantly enhances energy efficiency by minimizing drafts and heat loss, contributing to lower energy bills and a more comfortable interior environment. It also protects stored items from damage caused by moisture and debris, and reduces noise transmission. Historically, simpler methods like felt strips were used; however, advancements in materials science have led to more durable and effective sealing solutions, significantly improving garage functionality and longevity.
