Is Walsc AAC Panel System in compliance with NCC?

Short answer, yes.

All published Walsc wall and flooring systems are designed and tested in accordance with the requirements of NCC /Building Code Australia BCA. We also continue to invest in system development and conduct necessary testings and assessments to deliver more quality assurance, in respect of fire resistance, non-combustibility, acoustic reduction, thermal insulation, weatherproofing, structural etc.

Do Walsc AAC panels contain steel mesh?

Yes, all Walsc 50mm and 75mm AAC panels enhance the strength and security by combining with 1 layer of corrosion-protected steel mesh for durability.

Do I need to use long screws for horizontal panels above Doorset?

No, long screw fixing is only required if there is no 100mm notching at adjacent vertical panels.

Thermal resistance (R-Value)

Walsc AAC products provide excellent thermal resistance which reduces the need for heating and cooling systems within the residence.

  • 75mm R-Value = 0.52
  • 50mm R-Value = 0.34
Can I use Walsc AAC panels for buildings in bushfire prone areas?

Bush fire is a major challenge for the community. Buildings in bushfire areas can pose a series of challenges, both from a construction and a financial standpoint. Walsc external wall cladding systems are suitable for use in bushfire prone areas as they exceed the requirements for all six Bushfire Attack Level (BAL) levels.

Both Walsc 50mm and 75mm AAC panels can be used. The single layer panel wall can achieve a minimum 90mins fire rating and meet the acoustic requirement Rw+Ctr not lower than 50.

Walsc also introduces boundary wall systems which is suitable for where an external wall is being installed close to boundary and there is an existing building close to it on the opposite site of the boundary.

Can top hat batten run continuously at the control joint?

No, for all our vertical installed external wall systems, all the top hat battens have to be discontinued at the control joint to allow the building movement.

You will be benefit from less noise between floors and not get annoyed by squeaky floorboards due to seasonal changes in humidity levels and installation issues.
