How do you seal a bifold door?

by Mark MacDonald 04 Dec 2023

Bifold doors are a popular choice for hangars, garages, and various industrial spaces due to their efficient use of space and quick, reliable operation. Ensuring these doors are properly sealed is crucial for maintaining climate control, energy efficiency, quality of the contents, and overall security. But how do you do that? Fear not: in this post, we'll walk through the steps to effectively sealing a bifold door, providing you with the knowledge needed to enhance the functionality and longevity of your door.

Before delving into the sealing process, it's essential to understand the mechanics of bifold doors so you know why they need to be sealed the way they do. These doors consist of multiple panels hinged together, allowing them to fold horizontally. Bifold doors are renowned for their space-saving design, making them ideal for areas where traditional swinging doors may be impractical.

Bifold doors neatly fold away, maximizing available space. They open and close swiftly, allowing for efficient access. They are suitable for various applications, from hangars to residential garages. All this being said, sealing them effectively is of utmost importance.

Before sealing, carefully inspect the door for any damages or wear. Clean the surfaces, removing any dust, debris, or old sealant. A clean surface ensures better adhesion of the new seal.

Additionally, selecting the appropriate sealant is crucial. Consider factors such as the door material, the climate in your region, and the specific areas that need sealing. Common sealant types include silicone, weatherstripping, and adhesive-backed foam tape. For the sides and top of the door frame, weatherstripping is a highly effective choice. Measure the dimensions accurately and cut the weatherstripping to fit. Apply it along the edges, ensuring a snug fit when the door is closed.

The bottom of the bifold door is a critical area for sealing. Here, you can use a variety of options, including a door sweep or a threshold seal. Install the chosen seal at the bottom of the door, creating a barrier against drafts, pests, and moisture.

After applying the seals, carefully test the bifold door. Ensure that it opens and closes smoothly without any obstruction. Make necessary adjustments to the seals if needed. And know that sealing is not a one-time task; be sure to periodically inspect the seals for wear and tear. Replace any damaged seals promptly to maintain optimal performance.
