Seals on the top

The seals on bifold door seal replacement doors made of rubber can become flat or damaged over time. This can cause the loss of heat, draughts, and water ingress. Fitting new rubber seals is an easy and affordable solution to prevent these problems.

The top weather seal is designed to be attached in the space between the bifolding door and its frame. This seals the connections between the door and the frame. The quality of the material and manufacturing process used will determine how effective the seal is when used in. Triple glazing and class 4 airtightness are required for the highest quality bifold doors.

A very common problem faced by bifold owners a couple of years after acquiring the property is that their doors don't open because the threshold is no longer in line with the floor or exterior. The most typical "solution" to this issue is a seal with a brush, but it does not work in any way. The reason is that a brush is not able to compress against the threshold's surface, and so creates a gap that allows air and water in.

To stop this from happening the threshold of Lacuna is designed with a few steps. When doors are closed, they are pushed up against the threshold and then pressed into it. This is a superior alternative to the seals used by other products.

This option offers the additional benefit of not limiting the movement of doors when they are opened.

Seals should also be made from a tough material to ensure they can stand up to repeated use and harsh environments. To achieve this, the seals need to be made of high-performance materials like Neoprene.

The way a bifold door is constructed has a significant impact on its ability to prevent air infiltration and keep it out. The frame material and the type of glass and the amount of it will all affect 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 in easily. It's not always the case, however, and it depends on the design and installation of the doors.

If you're looking for an airtight bifold, you need to go for ones that have an excellent outer frame bubble gasket with zero-shrinkage nylon cord and a rubber flipper gasket seal on the inner face of the outer frame. They are designed to sit in the purpose made shoe ports, resulting in a high-performance seal when the bifold door sash closes to the frame.

It's crucial to select the correct sealant for the job, and it's recommended to apply a primer first to prepare the surface for the sealant. This will ensure that the sealant has the best adhesion possible and is long-lasting.

If you have an odd amount of bifold doors, they can only be opened at a certain height before they reach the threshold. This could cause drafts or heat loss.
