Bifold Door Seal Replacement

Bifold doors are a popular choice for hangars, garages and industrial spaces because of their efficient use of space and swift access. Making sure they are sealed properly is essential for energy efficiency and hygiene, as well as a pleasant indoor environment.

Gaskets can become flat, shrink or even break over time. This can cause water ingress and draughts, and heat loss. Fortunately, fixing this is easy and quick.

Seals on the top

Bifold doors with rubber seals can be slackened or damaged over time. This can cause the loss of heat, draughts, and water intrusion. Fitting new rubber seals is an easy and cost-effective solution to stop these issues.

The top weather seal is designed to be placed in the gap between a bifolding door and its frame. This seals the connection between the door and the frame. The quality of the material and manufacturing process used will determine how effective this seal is in actual. Triple glazing and airtightness of class 4 are required to ensure the highest quality bifold doors.

A common issue that bifold owners face a few years into ownership is that their doors don't open anymore because the threshold isn't flush with the floor or outside. The most typical "solution" to this problem is a seal with a brush, but it isn't very effective in any way. The reason for this is that a brush is not able to flex against the surface of the threshold which creates a gap that lets air and water in.

To prevent this, the threshold of Lacuna has been constructed with small steps. This means that when the doors are shut they are pushed against the threshold, and squeezed into it. This produces a much superior result than a simple brush seals that other products use.

This method offers the additional benefit of not limiting the movement of the doors when they are opened. If you choose to use the traditional bottom-hung method, doors can slide out because the track is beneath. It is often difficult to close the doors and cause them to slide away from the seals.

Seals at the bottom of the system are crucial to keep the doors shut and sealed to the floor. Seals are available in a variety of sizes and styles, but they must be put in the right place and of the right size. If they are too big they can cause friction between the bottom and the floor of the door. This could reduce the efficiency as well as wear and tear on the system.

It is also essential that the seals are constructed from a durable material so that they can withstand repeated use and harsh conditions. To achieve this, they should be constructed from an elastomer that is high-performance, such as neoprene or rubber. These materials are resistant to shrinking and stretching and will last a long time.

Seals on the Frame

Contrary to traditional doors that are hinged to open and close horizontally, bifold doors fold neatly away into the space behind them. They're a favorite choice in homes due to their superior space-saving capabilities. As with all doors, bifolds need to be properly sealed to avoid air leaks and drafts. This is where the rubber seals come in.

They are placed between the frame of the door and the bottom, creating a barrier to stop cold air from getting into your home. This allows heat to stay in during the winter and helps to reduce heating bills since it stops energy being wasted through the gap.

Silicone rubber, for example is a fantastic choice because it is able to endure a wide range of chemicals and substances, such as water, acid and animal/vegetable oils, oxidation, the effects of ozone, heat and UV light. The rubber seals that Lacuna employs are also thermally modified and are extremely durable. In fact the founder of the company once dropped a bifold door panel into a local harbour after which he waited for a couple of months, and then pulled it out to discover that it had not expanded or degraded in any way.

A rubber seal can also be installed on the top and bottom of the frame to stop air, water or sound from escaping. They are available in a variety of widths to suit different frames, and are simple to put in. The most important thing is to select an appropriate sealant that makes sure that it sticks to the surface and then apply it precisely to the edges of the frame.

The threshold is one last aspect to be considered when sealing the bifolding door. The thresholds are typically constructed with an upstand that helps to seal the bifold door, but the height can be problematic. This is because when you have an even number of bifold doors the doors are only able to be opened to an extent before they hit the threshold and lose heat or create drafts.
