There are many benefits of using bi-folding doors when finishing, renovating or remodeling an interior space. They can come in any design to fit a particular design style. A bi-fold door is a set of panels that has two or more hinged sections, usually folding in pairs. The doors can be opened from either side for one pair, or fold both sides for several pairs.

Larger bi-fold door systems are used as room dividers, barn doors, and even airplane hangar doors. They are usually hung from overhead tracks and suspended by rollers or casters. The innermost door panel has a knob or a door-pull which allows the user to fold the door panels together.

Bi-fold doors eliminate the problem of supporting a large overhead door in a commercial garage or airplane hangar with a low threshold options that offer unrestricted floor space. These doors can be hung in a series, making them ideal as room dividers. The same tracking used for sliding door systems can also be incorporated into bi-fold doors. The design of a bi-fold door allows the panels to fold on themselves without changing the orientation of the suspended casters or rollers. Because the tracks and casters receive some unusual stresses from the opening and closing action, bigger and heavier bi-fold doors are usually equipped with pivot floor tracks to prevent the panels from swinging and to add structural stability.

There are many different types of bi-folding doors currently on the market. Wood used to be the most widely used material, but now doors are also made of metal or glass. Some of them are available with a raised panel, flat panel, v-groove panel or as glass French doors.

Arguably, quite a few years ago, the most popular was the louvered door. A louvered door has stationary or movable wooden slats, or louvers, which permit open ventilation while allowing privacy and preventing passage of light to the interior. They can create dramatic sliding sashes to open up a room or building without reducing thermal or weather resistance.

Louvered bi-fold doors are usually used for closets and laundry rooms where ventilation is required. Smaller louvered bi-fold doors are also commonly used to form window shutters in many businesses and homes. Although bi-fold doors are not intended to secure things as a sturdy front door does, bi-folds can be used all around a home as interior shutters in place of curtains. This is not only an ideal solution for people with dust allergies but they can also provide maximum privacy when closed and floods space with light when open.

Other popular bi-fold doors are the mirror-paneled bi-folds. These are usually found in bedrooms and bathrooms of the home. Mirrored bi-folds may act as full-body mirrors and that is one of the traits that make them a favorite in the wardrobe area. Also specially effective in small spaces, mirrored bi-fold doors provide the illusion of having a bigger space when closed, yet allow maximum use of space in homes, restaurants, hotels, bars, or other interior spaces when opened.

With the advancement of technology doors are produced to be more energy efficient and attractive. Thermally broken aluminium Bi-folding doors are now designed to allow for maximal airflow through an opening. This Bi-folding mechanism is constructed using a chassis in which the movable parts strategically positioned so that the elements can be folded both left and right.

It is no wonder that new designs like the Visofold Panorama, which offers a slim line design; weather proof and virtually maintenance free, are used in homes, hotels, restaurants and stores for its space saving features.

Generally, having bi-fold doors installed is relatively inexpensive. However, the cost of having bi-fold doors can vary depending on the size, materials, and labour. Aside from all the benefits of using bi-folding doors, some can actually be installed by the homeowner themselves.

Although bifold doors come in different designs, the method of installation is the same. It's a good idea to read the instructions that came with the bifold doors before you begin. Generally the doors are 80 inches tall but can be cut down to fit. The height of the door opening should be two inches higher the length of the doors to allow enough clearance for the track and the rest of the hardware.

Start by marking the top of the opening with a pencil and line up the track. Mark and pre drill screw holes. (Use a drill bit that is smaller then the screw itself ).

Position the pivot brackets (inside the header track ) 3/8 inch away from the end of the opening.

Line up the pivot bracket with the header track. (You can use a plumb bob or lay a carpenters level against the side frame and make a mark at the floor and align the bottom track. I always take the measurements of where the top track will line up and transfer that measurement to the bottom where the pivot bracket will be installed).

If the floor is covered with carpet, you will need to use a wooden pad underneath the bottom pivot bracket. Cut away the carpet just enough to fit the wooden pad and fasten it down to the floor.

If it's a cement floor, use adhesive especially made for gluing to cement. Let the adhesive set for 24 hours, line up the pivot bracket with the top track and fasten it to the wooden pad.

Once all the brackets are lined up with each other and in place, you can hang the bifold doors by simply folding the doors in half and fitting the guide pin in the upper track. Next, lift up the door and fit the adjustable pivot into the pivot bracket at the bottom of the door opening.

Repeat the last steps for closets with four panels.

Install the doorknobs at a height where it is most comfortable to reach. Don't install the doorknobs too close to the edges.

If the opening requires four section bifold doors, you will need to install alignment brackets on the back side of the two middle doors. (Approximately 16 inches from the bottom of the doors). These brackets will interlock and keep the doors aligned with each other.

I hope this rough guide will help you understand how to hang bifold doors.

Bifold Door Sizes & Fitting

Bifold doors now form part of almost all new build home extensions due to their ability to open up large unobstructed openings allowing the new living space to seamlessly merge with the garden.

The enormous growth in demand for these folding sliding doors in the UK in recent years has led to a substantial increase in the number and type of different door systems now available to the consumer. They are now widely available in a choice of materials and finishes with the three most popular being thermally broken aluminium, upvc and hardwood.

Choosing the right bifold door for your project is an important decision and one that should not be taken purely based on cost alone. Your budget will naturally have an influence on your buying decision but there are other important factors that need serious consideration to ensure you are not disappointed with your purchase. Here are the top five points that are regarded by many as the most essential research when considering a bifold door purchase:

1. THERMAL PERFORMANCE

Since most bifold door installations will be subject to compliance with building regulations it is important to check that the folding door you are about to buy will meet your local authority's interpretation of current building regulations in terms of overall U-value performance. This calculation is based on the specification of the double glazing together with the profile design and dimensions to determine the insulation benefits of the door measured in U-values with the lower the value the better the insulation achieved. The minimum acceptable under current building regulations for replacement doors is a 1.8 U-value but some local authorities will insist on lower values particularly for new build extensions.

2. GLASS SIGHT LINES

Another important consideration should be the sight line or width of door profiles between each panel of the folding sliding door as this will affect the visible glass area available when the door is in the closed position. Most bifold doors are designed with dedicated profiles to minimise these sightlines as much as possible but some timber and many upvc folding doors use wide, chunky profiles that produce very broad sight lines in excess of 200mm wide that will ultimately spoil your view.

3. SECURITY

Most folding doors will feature a high security locking system but many still use face fixed or flag hinges that can pose a possible security issue and allow the hinges to be removed from the outside when the door is closed. Some upvc bifold doors may also use an exposed gearing system that is accessible from the outside of the door when the door is closed which can also pose a possible security threat. You can eliminate these potential security problems by ensuring you choose a folding door that has fully concealed gearing and hinge fixings.

4. THRESHOLDS

Although a flush threshold is the most popular option especially for internal bifold doors this may not always be practical in some cases and a conventional raised threshold will need to be used. It is important to note that the height of these can vary considerably with some upvc bifold door thresholds exceeding 125mm. Such a high 'step-over' threshold may create an accessibility issue for children and the older generation. The latest bifold door designs offer raised thresholds designed to minimise the trip hazard with some offering thresholds as low as 50mm high.

5. TOP HUNG OR BOTTOM ROLLING

Some bifold doors are hung from the top to allow for a minimal threshold at floor level but with all the weight of the door being supported from the top a substantial upgrade of the lintel is normally required for strength and stability. Bottom rolling folding doors are a cost effective and popular alternative since the weight of the door is carried at ground level rather than suspended from the lintel.

Whether you decide on an aluminium, upvc or hardwood bifold door it is a major purchase for your project and one that should be carefully considered to ensure the very best value for your money. Buying a cheap bifold door may prove a disappointment unless you check carefully that the door you are buying will meet your needs and expectations before you order.

Bi-fold doors are already popular as an interior feature, and they can also be very practical, useful and aesthetically pleasing when used as exterior doors. There are a number of benefits that these doors can bring to your home, and these can really enhance its value as a pleasant and practical place to live.

Space-Efficient

Bi-folding doors are a very space-efficient entrance/exit solution. Traditional doors swing directly inwards or outwards. Not only does the full width of the door stick out into the room or the space just outside of your home, but it also requires a clear route throughout its swing. If any object is in the way, such as a pair of shoes or a plant pot, this will prevent it from opening fully and this can be a pain. Because they fold, and because they slide within the door frame rather than swinging outwards, bi-fold doors do not require as much clearance in order to open and close fully. This is convenient for just about every kind of home, but especially for those with a lack of space or where you want to make use of the area immediately surrounding the door.

Long-Lasting

A good-quality folding door will last for a long time and provide you with a lengthy service life before eventually needing to be replaced. However, cheap bi-fold doors can be problematic, as they have more moving parts and more intricate and complex mechanisms than standard doors. Nonetheless, good, well-made uPVC bi-fold doors will use high-quality materials and manufacturing techniques to provide a door that will last a long time.

Versatile

UPVC bi-fold doors are extremely versatile, as they come in a range of sizes and types. You can choose from various configurations with different numbers of panels and various folding points in a very wide range of sizes. You might replace an existing set of double doors with a two-panel bi-folding door, for instance, or else have anything up to seven panes of glass for a vast panoramic view of the world outside your home. In fact, larger bi-folding doors are particularly useful for allowing to you admire the outdoors. With full-length panes of glass, wider multi-panelled doors give you a complete view of the outside even when you are inside with all the doors and windows closed. This is perfect for enjoying the outdoors and admiring your garden in warmth and comfort during the winter. In summer, all of the many panels can be pushed aside providing not just a complete view of the outside, but plenty of fresh air and room for even large numbers of people at a gathering to move freely between the inside and outside of your home.
