Seals on the Top

The seals on bifold doors made of rubber can flatten out or become damaged over time. This can cause draughts, heat loss and water ingress. Installing new rubber seals could be a cheap and easy solution to these issues.

The top weather seal for a bifold door is designed to be secured in the gap between the doors and frame, sealing this connection with the structure. The quality of the materials and manufacturing process used will determine how effective this seal is in actual. The best bifold doors can be airtight to class 4 and a U-value that is below 1.0 with triple glazing.

After several years of ownership, bifold owners often notice that their doors don't open any longer. This is because the threshold has moved and is no longer flush to the floor or to the outside. The most common "solution" to this issue is a seal with a brush, but it does not work in any way. This is due to the fact that a brush is unable to compress against the surface and creates gaps that allow water and air to pass through.

To prevent this the threshold at Lacuna's has tiny steps incorporated into it. When the doors are closed they are pushed upwards against this threshold, and then pressed into it. This is a superior solution than the seals that are used for brush by other products.

This option comes with the added benefit of not limiting the movement of doors when they are opened. If you choose to use the traditional bottom-hung method, doors can slide out due to the track being beneath. This makes the doors hard to close and push away from the seals if they're not fully compressed.

Seals come in a variety of sizes and styles, however they must be placed correctly and the correct size. If they are too large they could cause friction between the bottom of the door and the floor, which will reduce the efficiency of the system as well as increase wear and tear on the door.

Seals should also be made of a strong material so that they can endure repeated use and harsh environments. To ensure this, they must be made of an elastomer that is high-performance, such as neoprene or rubber.

Seals on the Frame

They are available in different sizes to fit different frames and are easy to install. The trick is to select the right sealant to make sure that it sticks to the surface, and then apply it to the frame's edges.

The threshold is the final area to consider in sealing the bifolding door. The majority of thresholds have an upstand to help to ensure that they are sealed tightly against bifold doors, however the height can be an issue. This is because if you have an even number of bifold doors they are only able to be opened to a certain point before they reach the threshold and lose heat or create drafts.
