What is the process of installing a Bi-fold door?

The first thing that needs to be checked is that the lintel is in place and strong enough to support the weight above the opening.

If you want the opening to be considerably more significant than it is now, there may be structural work as well as installation expenses involved. A structural engineer may need to be consulted at this stage.

If the aperture is to be made larger this work will be carried out before the installation team visits and will require a specialist builder to undertake the work. All this will be taken care of by our expert team.

Installation of bifold doors varies depending on the type of bifold doors you choose. Folding doors are usually installed in one piece; however, some manufacturers weld the frames on-site to make them easier to transport.

Which is better, sliding doors or bi fold doors?

Sliding doors require huge glass panels to cover the same area as folding doors. These large toughened glass panels can be cumbersome, which takes a toll on the mechanical parts of the sliding door.

While we feel there is a place for sliding doors, bi-fold doors are much better suited to larger openings.

All doors will be fitted with toughened safety glass as standard, and this can add a considerable amount of weight to the frames.

Finally, to sum things up

Bifold doors are an excellent renovation choice for homeowners looking to add value to their properties. When choosing bifold doors, there are a few things you'll need to consider: the size and shape of your door opening, the type of glass used in construction, frame material and whether the installation is to be included in the price. If all this sounds intimidating, please call our expert team to discuss your options and find the perfect bifold doors for your home.
