Improved Thermal Performance with Enhanced U-Values

One of the most significant upgrades to the Visofold 1000 is the improved U-values. U-value measures how well a door or window insulates against heat loss, with lower values indicating better insulation. This upgrade means the door now offers better energy efficiency, helping to reduce heating costs and improve comfort inside the home.

The enhanced U-values are achieved through:

• New rebated outer frames: The introduction of two new frame options, DV17 and DV19N, provides better sealing and thermal breaks.

• Integrated cill design: This new cill improves the door’s thermal barrier at the base, reducing cold spots.

• Low threshold option: Retained from the previous model, this option supports accessibility while maintaining thermal performance.

  
  

These improvements make the Visofold 1000 a strong choice for homeowners focused on sustainability and energy savings without compromising on style.

Easier and Quicker Fabrication and Installation

The upgraded Visofold 1000 also addresses the practical needs of fabricators and installers. The new design simplifies the manufacturing process and reduces installation time, which can lead to cost savings and faster project completion.

Key features supporting this include:

• Streamlined frame profiles: The DV17 and DV19N frames are designed for easier cutting and assembly.

• Integrated cill: This reduces the number of separate components needed, simplifying installation.

• Compatibility with existing hardware: The upgrade maintains compatibility with current Visofold hardware, avoiding the need for new tools or training.

  
  

For builders and installers, these changes mean less hassle on site and more predictable timelines, which benefits both contractors and clients.

New Heritage Style Sash for Classic Appeal

While the Visofold 1000 is known for its modern slimline look, the upgrade introduces the DV225 heritage style sash. This addition aligns the bi-fold door with Smart’s established range of heritage windows and doors, offering a traditional aesthetic without sacrificing performance.

The heritage sash features:

• Classic proportions: Thicker profiles and traditional detailing that suit period properties.

• Modern thermal efficiency: Despite the classic look, the sash maintains the improved U-values.

• Versatile design: It can be combined with the new outer frames and cill options for a tailored finish.

  
  

This option expands the door’s appeal to homeowners and architects working on renovation projects or those who want a timeless style with modern benefits.

Practical Benefits for Homeowners

The upgraded Visofold 1000 slim bi-fold door delivers several advantages for homeowners:

• Energy savings: Improved insulation reduces heating bills.

• Enhanced comfort: Better thermal performance means fewer drafts and cold spots.

• Flexible design: Choice of slim modern or heritage style sashes to suit different home styles.

• Easy access: Low threshold option supports smooth transitions between indoor and outdoor spaces.

• Quick installation: Faster fitting reduces disruption during home improvements.

  
  

These benefits make the door a smart investment for anyone looking to improve their living space with a stylish, functional opening.

Installation Tips and Considerations

To get the most from the upgraded Visofold 1000, consider the following during installation:

• Choose the right frame: Select between DV17 or DV19N based on site conditions and aesthetic preferences.

• Plan for drainage: The integrated cill helps with water management, but proper site drainage is essential.

• Check compatibility: Ensure the heritage sash option fits the overall design scheme if chosen.

• Work with experienced installers: Although installation is easier, professional fitting ensures optimal performance.

  
  

Following these tips will help maintain the door’s durability and efficiency over time.
