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.

Bifold Door Sizes & Fitting

Bifold doors have much greater flexibility than sliding patio doors or French doors. They can be fully opened, completely closed, or partially opened depending on the amount of space required. Their ability to connect the inside to the outside is unsurpassed. For example they allow the whole of the back wall of a house to open out onto the garden.

Doors are available in a range of materials including PVCU, aluminum, timber and aluminum-clad timber. The latter, although expensive, allows hardwearing aluminum on the outside and an attractive wooden finish on the inside. PVCU doors are usually the cheapest option but are limited in colours (white). Aluminum doors can be powder coated so are available in almost any colour or finish. Timber doors are usually made of hardwood or laminated timber. The latter is essential if the door were in a South facing, exposed or coastal position. In that location environmental extremes would cause hardwood doors to warp and malfunction. Any reputable bi fold door manufacturer will advise you of the best choice for your situation.

When choosing bifolding patio doors it is essential that you select ones that are constructed to the latest regulations. They must be completely weather proof in even the harshest conditions. The glazing must also be optimised to give the best thermal insulation. Other considerations are the size and number of panels, how these panels can be configured, the type of door threshold and the location of trickle vents. Quality gearing is also essential if you want smooth and durable door performance.

These kinds of doors are becoming more and more widely shown in the media. They are often seen in home renovation or remodelling TV shows to provide that elusive wow factor. Their versatility in configuration and availability in various materials make Bifold doors a tempting option for anyone considering installing or upgrading a traditional patio door.

As with most reasonably large property expenditure, a bifold door normally a one-off purchase. The technical detail is likely to leave the average consumer confused, so what is involved in choosing a bifold door that will allow you to enjoy your home more, will be versatile, and will look and function beautifully for many, many years?

Below are some tips on what to consider, but we suggest you look for a bi folding door specialist to supply and fit your door who will perform a survey before building your door and give you any advice you need. Should you decide to use your builder or a professional fitter, they should take responsibility for the precise measurements and ancillary requirements for the door. In unskilled hands, these doors are likely to produce problems so an experienced installer should be used. However, you may well prefer to perform your own research and we hope that these tips prove useful.

Essential Considerations

• Which material - aluminium, PVCu or timber products
• Configuration options - how should it fold and open
• Size and number of panels
• Glazing - for thermal, privacy and appearance
• Threshold Options - for accessibility and weatherproofing
• Trickle Vents - for ventilation and to meet building standards
• Gearing - for smooth operation and high performance
• Cill and Drainage - are they necessary for your project

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 iin 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.

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.

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.

Trickle Vents

Trickle vents, or night vents, are built into the frame to provide exchange of air and to prevent condensation. These are compulsory for new builds and may be appropriate for your installation for other reasons. Any bifold door specialist can advise, but you should check with your builder or installer.

Cill and Drainage

You may or may not need a cill and/or drainage which will be specified at the survey. Drainage is via a narrow channel which draws moisture away from the door and whether drainage is required will be depend upon internal and external levels and other factors.
