Most newly built extensions in medical centers around New South Wales are now installing bifold doors since they open up to large openings without obstructions. This makes it possible to merge areas within the hospital for easy access.

The increasing demand for bifold doors across Sydney has contributed to the manufacture of more types of door systems for consumers to choose from. They are also available in different finishes and materials to choose from. The most popular ones are hardwood, aluminium, and uPVC.

Choosing the ideal aluminium windows and doors are crucial and making this decision should be based on many factors and not just cost. Your budget always has a natural influence on the choices you make but there are other crucial factors that should be considered. Here are the most important factors to consider when choosing these doors:

 

Thermal Performance

Installation of most of these doors demands compliance with local authority building regulations. Hence, you should check whether the door you want to buy meets the regulations of your local authority with respect to its U-value rating. The U-value of a door is usually based on its insulation performance.

This depends on the door’s design, dimensions, and whether it is double glazed. A door with a lower U-value has better insulation than the one with a higher U-value. The minimum U-value accepted by most regulations is 1.8. However, some local regulations may demand lower U-values especially for new extensions.

 

Sight Lines

The sight line of glass is another crucial factor you should consider. This is the width of the door between the panels of the door. It affects the glass area that is visible once the door is closed.

The best doors to go for are those designed with the most minimal sight line. Many wooden and uPVC doors tend to use designs that leave broad sightlines and this spoils the view. Hence, go for the type with minimal sightlines for a better view.

 

 

Security for Bi-folding Doors

The best doors to go for are those that have advanced locking systems. Some doors still use flag or face fixed hinges and this poses major security issues since the hinges may be removed easily from the outside.

Others may have exposed gearing systems that are easy to access from outside, and this will also pose security issues. You should eliminate such security issues by going for doors with fully conceal hinges and gearing systems.

 

Thresholds

One of the most widely used options for internal doors is the flush threshold, but it is not always practical for some applications. A conventional threshold may be used in other cases.

The height may vary and exceed the threshold of 125mm in some uPVC doors. Such a threshold may result in accessibility issues for the elderly and children. Modern designs come with raised thresholds that are designed to minimize trip hazards with some having low thresholds of 50mm.

 

Bottom or Top Hung Rolling

Some doors are usually hung at the top with the aim of guaranteeing minimal threshold from the floor, while the rest of the weight is supported at the top. In such a case, the lintel should be upgraded to ensure it has enhanced stability and strength.

The bottom rolling ones are more popular and less costly since the door’s weight is carried on the ground level instead of being suspended from a lintel.

Whichever material you decide to choose, be it hardwood, UPVC or aluminium, just make sure you select the best door based on all the described factors. Buying a bifold door because it is cheap may end up disappointing you in the long run. Hence, ensure you choose the door that’ll meet your expectations and needs before making an order.
