bifold doors Manfacturers in Westminster
Aluminium is a fabulous, highly durable, low maintenance material. It is available in a vast range of colours, wood effect and metallic finishes. It needs only to be washed occasionally to keep it clean and looking new.
Aluminium is less expensive than timber options, but some Westminster properties – especially period and listed properties where existing fenestration is traditional – may not be entirely suited to aluminium or even meet planning guidelines.
PVCu is the least expensive option. It is available in a range of colours and finishes, but responsible bifold door manufacturers would not recommend anything other than a standard white PVCu finish. This is because colour and finishes can cause instability to this material when in conjunction with the movement of the bifolding door.
PVCu is easy to maintain, does not last as long as aluminium, but will still look beautiful after several years. Good quality, modern PVCu can complement white timber windows and doors very well.
Timber bifolding doors in Westminster can be built in hardwood or in laminated (engineered) timber. Engineered timber is designed to outlast other timber products as it is formed from layer upon layer of hardwood, preventing water from becoming trapped within the wood where it can causing twisting and shrinking and eventual damage. The fold and slide nature of bifolding doors means that they are highly sensitive to any alteration of shape and weight distribution and this will result in stress on the gearing, poor performance and eventual breakdown.
In South facing, exposed or coastal areas laminated timber is recommended over hardwood for this reason. All timber bifold doors can be factory painted in an infinite range of colours and this should assure a guarantee of long durability of the finish and low maintenance.
BIOFOLD Opening Configurations
A flexible supplier of bespoke doors in Westminster will be able to offer all possible configuration options to suit your aperture, but there will be technical limitations. Each panel has to be attached to the track, which affects which doors can be free one side to open. Options can include a single opening door at either end or anywhere it makes physical sense along the track. It is possible to use two of the doors as french doors in the conventional way whilst the remainder of the panels are closed as long as there are enough panels.
Size and Number of Bifolding Panels
Panel size is dictated by material and is essentially weight related. Once glazed, these doors are very heavy and too much weight can affect their performance. If narrow, the panels will become too bulky to fold and slide and will be cumbersome when stacked away.
The standard maximum width of an aluminium bifold door is 1000mm and there are height restrictions which, if exceeded, may cause issues and customers will be expected to sign a disclaimer. PVCu may be lighter than aluminium, but because it is not as strong, a good bifolding door company will ensure that all of its PVCu bifolds are reinforced with steel, thus making it heavier.
The number of panels a door comprises should be flexible if custom built. Generally, however, fewer panels in a door makes for better visibility. In addition, the price per square metre increases in line with the number of panels owing to the additional material, engineering, hinges, security and thermal requirements.
Gearing quality is critical to door durability and performance. Unfortunately, it is also the feature you may not be able to qualify yourself. For this reason, if you do not know of a bifold door specialist, it is recommended that you use either a reputable company experienced in supplying bifold doors or a reliable builder or architect to specify the door. Choosing a product on price frequently leads to disappointment.
All bifold doors are most weatherproof when incorporating a normal threshold – no matter what manufacturers say to the contrary. By its very nature, a low threshold bi-folding door is subject to some water and draught ingres in severe conditions. Low thresholds are fabulous for disabled access and level access to, for example, a garden, but consider your property’s aspect, your geographical location and local weather patterns before making a decision. And as an extra precaution, lay water resistant flooring immediately inside a low threshold.
Bifold Doors Glazing
Glazing should be 28mm K glass or equivalent and is always double glazed. It can be obscured if required, self-cleaning and have heat resistant film applied if in direct sunlight. Increasingly popular are internal blinds which are very attractive, but which are new on the market and have no history on which to stake their durability.
Bi-Folding Doors - The Benefits of Using Them
A bifold door is a door that has multiple sections, folding in pairs. The doors can be opened from either side for one pair, or fold off both sides for two pairs. Wood is the most widely used material, and doors may also be made of metal or glass. Bifolds are usually designed for closets, but may also be used as passageways between rooms. They are a great asset to any home or apartment and drastically enhance the light in the room.
There are many different kinds of bifold doors currently on the market. Arguably the most popular is the louvered door. A louvered door has stationary or movable wooden panels (often called slats or louvers) which permit open ventilation while allowing privacy and blocking the passage of light inside. Being moderately weak structures, they are generally used for laundry rooms and closets, where effective is required. Smaller louvered bifold doors are also commonly used to form window shutters in most homes and businesses.
Other popular ones are mirrored. These are most common in bedrooms and bathrooms of the home. Mirrored bifolds may act as full-bodied mirrors, and that is one of the traits that makes them common in the wardrobe. Another popular one is the raised-panel bifold. These doors are the work of fine craftsmanship and have a very elegant look. The raised panel is achieved on these doors by sawing or etching designs into the wood of the doors that give them a "raised" look. These are commonly installed in bedrooms, kitchens and pantires.
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.
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.
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.
