Seals on Top

As time passes, the rubber seals on a bifold will get damaged or flatten. This can lead to draughts, loss of heat as well as water intrusion. Installing new rubber seals is an easy and cost-effective solution to stop these problems.

The top weather seal is designed to be positioned to the gap between a bifolding door and its frame. It seals the connection between the door and the structure. How effective this seal will be in practice is contingent on the quality of the material and the manufacturing process. Triple glazing and class 4 airtightness are required for the highest quality bifold doors.

A common issue that bifold owners face a couple of years after acquiring the property is that their doors don't open anymore because the threshold isn't in line with the floor or outside. The most typical "solution" to this problem is the use of a seal made by a brush, which does not work at all. The reason for this is that a brush is unable to flex against the threshold's surface, and so creates a gap which lets air and water in.

To prevent this, the threshold of Lacuna has been constructed with a few steps. When the doors are closed they are pushed against this threshold, and are compressed into it. This produces a much better result than the simple brush seals that other products utilize.

Another advantage of this method is that it doesn't restrict the ability of the doors to move when opened. In contrast, if you have a traditional bottom hung system, the doors are able to be opened by sliding them open since they are supported by the track underneath them. This makes doors difficult to close and push away from the seals if they're not fully compressed.

Seals are available in a variety sizes and styles, but they must be installed correctly and of the right size. If they are too big they can cause friction between the bottom and the floor of the door. This can decrease the efficiency and wear and tear of the system.

It is also crucial that the seals are constructed with a strong material to ensure that they can stand up to frequent use and harsh conditions.

The way that the bifolding door is constructed will have a significant impact on the ability of it to block air infiltration. The frame material and the glass type and the quantity of it will all impact its thermal performance. (Ideally you'll want to have a U-value less than 1.0 for double glazing).

A lot of people think that their bifold doors are inherently poor in sealing and allow drafts through easily. This is not always the case, however, and it is dependent on the design and construction of the doors.

If you are looking for an airtight bifold, look for ones with a premium bubble gasket for the frame's outer face with a zero-shrinkage cord and gasket seal made of rubber on the inner face of the frame's outer surface. These are designed to fit inside the shoe ports and form a high-performance seal when the bifold sash shuts.

It's crucial to select the right sealant for the job. It's recommended to apply a primer before applying the sealant to prepare the surface for the sealant. This ensures the highest possible adhesion and longevity of the sealant.
