Bifold Door Seal Replacement
Due to their space-saving design and ease of access Bifold doors are a popular choice for garages, hangars and other industrial spaces. It is crucial to seal them for energy efficiency, cleanliness, and a comfortable space.
As time passes, gaskets become flat, shrink or get damaged, leading to water ingress, draughts and loss of heat. This is a simple and quick fix.
Seals on the top
Bifold doors with rubber seals can become flat or damaged over time. This can lead to draughts, heat loss, and also water ingress. Installing new rubber seals could be a simple and cost-effective solution to these issues.
The top weather seal is designed to be attached 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 will determine how effective this seal is when used in. The best bifold doors will achieve class 4 airtightness and a U-value of below 1.0 with triple glazing.
After a few years of ownership, owners of bifold doors frequently find that their doors won't open anymore. This is due to the threshold having moved and is no longer in line with the floor or to the exterior. The "solution" is usually a brush seal which does not work well. This is because a brush cannot compress against the surface, and it creates a gap that allows water and air to pass through.
To avoid this the threshold of Lacuna has been designed with small steps. When doors are closed, they are pushed upwards against the threshold and are compressed into it. This provides a better result than the simple brush seal that other products use.
Another advantage of this method is that it doesn't limit the ability of the doors to move when opened. When you use the traditional bottom-hung method, doors are able to slide out due to the track being beneath. It can make it difficult to close the doors and cause them to move away from the seals.
The kit comes with a premium outer frame gasket with a nylon core that shrinks to no more than hair, a flipper for the outer frames to create a seal on the closed sash and wedge seal as well as E type seals for the inner frames.

Seals at the bottom of the system are crucial to ensure that the doors are closed and sealed to the floor. There are various options for these seals but it is important to choose the right size for the door and that they are installed correctly. If they are too big, they can cause friction between the floor and the bottom of the door. This could reduce the effectiveness and wear and tear of the system.
Seals should also be made of a durable material, so that they can withstand repeated use and harsh environments. To do this, the seals should be made from a high-performance material such as neoprene. These types of materials have great stretch and shrink resistance and will give a long life to the door.

The way a bifolding door is constructed has a huge impact on its ability to stop air infiltration. The frame material, the type of glass and the quantity of it all affect its thermal performance. (Ideally you'll want to have a U-value below 1.0 for double glazing).
Many people believe that bifold doors are inherently poor in sealing and allow drafts through easily. However, this isn't always the case it is all dependent on how the doors are designed and installed.
If you're looking for an airtight Bifold, look for those that have a premium bubble gasket for the frame's outer face with a no-shrinkage cable and gasket seal made of rubber on the inner face of the outer frame.

One last thing to think about when sealing a bifold door is the threshold. The thresholds are usually designed with an upstand that helps them seal tightly against bifold doors, but the height can pose a problem. If you have an odd number of bifolds, the doors can only be opened at a certain height before they reach the threshold. This can lead to heat loss or drafts.
