The sealing material fitted around recreational vehicle entryways prevents the ingress of water, air, and pests. This barrier typically consists of flexible, durable materials like rubber or vinyl, designed to conform to the door frame and create a tight seal when the door is closed. An example would be the D-shaped profile often used on the side of RV doors to seal against the frame.
A properly functioning seal is crucial for maintaining a comfortable and protected interior environment. It minimizes drafts, reducing the load on heating and cooling systems, thus improving energy efficiency. Protecting against water damage is another key benefit, as leaks can lead to costly repairs and structural issues. Historically, simpler materials like felt or foam were used, but advancements in material science have led to more durable and effective solutions designed to withstand the rigors of the road and varying weather conditions.
