Seals on Top
The seals on bifold doors made of rubber can flatten out or become damaged over time. This can cause draughts and loss of heat and also water ingress. Installing new rubber seals can be a cheap and easy solution to these issues.
The top weather seal is designed to be placed in the space between the bifolding door and its frame. This seals the connection between the door and the frame. How effective this seal will be is contingent on the quality of materials and the manufacturing process. Triple glazing and airtightness class 4 are essential for the highest quality bifold doors.
A very common problem that bifold owners face a few years after they have purchased the property is that their doors won't open because the threshold isn't in line with the floor or the exterior. The most common "solution" to this issue is a brush seal, which doesn't work very well at all. This is because a brush is unable to compress against the surface, and it creates gaps that allow water and air to enter.
To avoid this, the threshold of Lacuna has been designed with a few steps. When the doors are closed they are pushed against this threshold, and are compressed into it. This is a superior alternative to the seals used by other products.

Seals must also be constructed of a strong material so that they can withstand repeated use and harsh environments.
