With this increase in weight loading, rollers are critical to the function of windows and doors. They can be the difference between having a smooth operating sliding door and a fixed glass pane. It is essential that when choosing your rollers you spend the time to asses the options available. Be weary of anyone telling you that one roller does all, although they may all look the same they’re not.

The introduction of energy efficiency regulations throughout Australia has increased awareness of the significance energy efficient windows and glass sliding doors can play in achieving a house’s energy rating. One of the main products in the building industry that help’s improve insulation is double glazing, this can be used everywhere from the largest office block, to domestic windows and doors. Some of the major benefits of double glazing are as listed:

  • Save money with reduced heating and cooling bills.
  • Reduced greenhouse emissions.
  •  Improves insulation.
  • Reduces cold spots and down draughts.
  • Makes good use of the sun's heat.

Double glazing and taller ceiling heights both play a major part in the increasing weight of window and door systems. Due to the changes in this market, heavier loads are being demanded from sliding window and door products.

Unfortunately most builders and home owners will only notice when the product fails to perform, and this can lead to customer dissatisfaction. 

So what to look for?

Load capacity is usually considered when making a selection but is often poorly understood. As a general rule the contact area of the bearings is what determines the load capacity. However the bigger the bearing, the larger the contact area and diameter. This generally creates a problem as it requires additional room in the height of the frame.

To overcome this, dual wheel carriage designs are available to distribute the load over two wheels. When selecting this option ensure that the carriage pivots form a central position, for if the assembly does not pivot, one wheel will be taking the load which defeats the purpose of having a dual wheel roller.

Anthony Innovations produce a wide range of door and window rollers that have load capacities between 50kg to 200kg, which helps address this issue efficiently and effectively. If you have any questions on any of the above, please feel free to contact us on 1800 664 696.
