Description

The Eldorado Stone™ Veneer and Hard as Rocks Application System is a cavity-based external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The system consists of a cast stone veneer cladding designed to imitate the look of natural stone. The stone veneer elements are manufactured from lightweight aggregates, Portland cement and iron oxide pigments, and are cast to mimic different types of stone. Fibre cement backing sheets are fixed over timber battens to form a 20 mm cavity.

The stone veneer and mortar are mechanically anchored through to the structural wall framing by stainless steel anchor ties and screws. The system incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 20 mm drained cavity.

Scope

The Eldorado Stone™ Veneer and Hard as Rocks Application System has been appraised as an external wall cladding system for buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; and,
  • constructed with timber framing complying with the NZBC; and,
  • with a risk score of 0-20, calculated in accordance with NZBC Acceptable Solution E2/AS1, Table 2; and,
  • situated in NZS 3604 Wind Zones up to, and including, 'Extra High'.

The Eldorado Stone™ Veneer and Hard as Rocks Application System has also been appraised for weathertightness and structural wind loading when used as an external wall cladding for buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with regards to floor area and building height; and
  • constructed with timber framing complying with the NZBC; and,
  • situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 2.5 kPa.

The Eldorado Stone™ Veneer and Hard as Rocks Application System must only be installed on vertical surfaces (except for sills which must have a minimum 10° slope and be waterproofed in accordance with the Technical Literature).

The system is appraised for use with aluminium window and door joinery that is installed with vertical jambs and horizontal heads and sills. (The Appraisal of Eldorado Stone™ Veneer and Hard as Rocks Application System relies on the joinery meeting the requirements of NZS 4211 for the relevant Wind Zone or design wind pressure.)
