Nufold Bifold Doors - Feature - Roller System

Roller System

Centor E2 Stainless Steel Top Hung Weatherproof Roller System

This impressive roller system allows door panels to snugly close against rubber weather seals, giving it superior rain and wind resistance.

The resistance to air infiltration is up to 50 times better than the average sliding door, which adds additional acoustic sealing qualities (reducing the transfer of sound, especially when E2 is used indoors.)

The sliding system uses a floating wall pivot to control door stile deflection and bowing on tall doors caused by wind loads or climatic conditions.

Proven Performance

Produced in the highest grade stainless steel and engineering grade plastics, individual E2 components have undergone extensive laboratory testing.

This includes cyclic testing (to 50,000 cycles) as well as corrosion testing, structural testing and finite element analysis. The stainless steel bearings are custom machined to fine tolerances and machined wheels are individually precision ground to an ultra-fine hone. This results in a top-hung design with unparalleled performance and a perfectly fluid gliding function.

Solid 54mm thick door

Nufold’s thick doors save money on energy costs by reducing heat exchange between inside and outside.

These incredible 54mm thick doors improve the thermal break and allows for a 24mm double-glazed unit.

Nufolds engineered core will always outperform one-piece solid hardwood doors and has been developed to withstand the harsh Australian climate. These doors also come with a range of benefits:

  • 10 Year warranty.
  • Stability by design, engineered to prevent the natural tendency of wood movement such as warping, shrinking, splitting or twisting.
  • White Aluminium clad option for maintenance free exterior.
  • Superior insulation.
  • Sleek 80mm door rails to allow for more glass.

Multi-locking System

5 unique locking points for added security

Never worry again about security with Nufold’s 5-point multi-locking system, which has been designed to meet the requirements of PAS 24 as part of a compliant door system, and BS 6375.

This comprehensive system enables the doors to come with a range of benefits, including:

  • A central brass deadbolt, which has a thickness of 22mm to prevent unauthorised entry.
  • Bi-directional throw of locking.
  • Enhanced anti-jemmy feature.
  • Four high security hooks for anti-separation resistance - 10mm (maximum) engagement into keeps.
  • Hooks deadlocked in the fully thrown position.

This ensures that the level of security these doors provide is second to none, so you can rest assured that you don’t have to sacrifice security for a better lifestyle.

Trim Pack

If the frame doesn’t quite fit your opening, don’t worry. Just add one of our trim packs to make up the space!

By simply fixing your frame in place and using our trims, you can cover up to a 45mm gap on each side and the top of the frame.

Aluminium angles are available in two sizes- 45mm and 70mm. These also come powder coated to match the frame.

Timber trims come coated with the same 4-coat technology as the frame. They are 67mm wide and can easily be cut to suit different sized gaps.

Nufold Bifold Doors - Feature - Glazing


  • 24mm Double glazed Units.
  • Low E Toughened glass.
  • Argon gas filled.


4mm glass u value 5.9
6mm glass u value 5.7
6mm Low E u value 3.7
Standard 24mm double glazed unit u value 2.7
Nufold double glazed u value 1.7

In our double glazed units we use energy efficient Low E (low emissivity) glass. Low E glass has a microscopically thin, transparent coating (much thinner than a human hair) that reflects long-wave infrared energy (heat). Some Low E's also reflect significant amounts of short-wave solar infrared energy.

This reduces the transfer of heat between the indoors and outdoors. During winter, this means that warmth is kept inside the home. In summer, this means that heat is kept outside the home.

This has the wonderful effect of helping you save money on your energy bill, making Nufold doors a both an aesthetic and financial investment into your home.


Nufold doors come with the option of a Brio 612 Retractable Pleated Insect Screen, so you can bring the outdoors into your home without the pests that normally come with it.

The impressive 3.2 metre and 9 metre wide span (double screen) does not compromise views or ventilation and functions independently of the door system.
