Bifolding Door Frames

When selecting a frame always take into consideration three important aspects, for instance, appearance, location and budget. The cheapest frames are the uPVC door frames while the moat costly frames are those made of woods. While considering appearance you need to remember few things, for example, uPVC door frames are not available in a wide range of finishes while aluminium and wooden bifolding door frames, on the other hand, are obtainable in an extensive range of colours. Moreover, if you prefer contemporary look then aluminium and uPVC are the best choice for you while wooden doors tend to have a more natural and traditional look.

Finally, when thinking of location you require determining where you will be fixing the door frame. For instance, wooden frames are ideal for doors which are sheltered from extreme weather conditions as wood is not a highly durable material.

Bifolding Door Glass in Berkeley

Doors are made of different types of glasses, such as, double glazing, which tend to be the regular glass for these types of doors, tempered glass doors are known for their strong and additional safety properties, low-e glass comes with a heat reflective coating and lastly the laminated glass, which is made up of double sheets with a plastic layer in between and tend to be highly secured and safe.

Material

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 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 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.

Opening Configurations

A flexible supplier of bespoke doors 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.

Bifold Gearing

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.

Thresholds

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 Fold Doors - Give More Creative Living Space

Overview - Clearly bifolding doors are not a cheap alternative to the traditional sliding door, but what are the real gains in making the extra investment. The most apparent is the fact that folding sliding doors are fully retractable. The commonly known French door is just a permutation of a bifolding door and most bifolding door manufacturers will be able to make their system into a french door. A French door is a double pane system which opens in the middle so the both leafs are fully open and set at right angles to the track. They have been very popular over the years and can allow for an elegant opening mechanism with great clear glass views. Please find the strengths and weaknesses of the bifolding door below.
