Description

Solitex Extasana Wall Underlay is a flexible synthetic wall underlay for use under direct fixed and non-direct fixed wall cladding on timber and steel framed buildings.

The product consists of a non-porous water resistant film laminated between two layers of non woven spun-bonded polypropylene and is coloured blue on the top surface and grey on the bottom surface.

Scope

1. SOLITEX EXTASANA® Wall Underlay is suitable for use under wall claddings as a wall underlay as called up in NZBC Acceptable Solution E2/AS1 (AMENDMENT 10 – 05 November 2020), Table 23 on timber framed buildings and NASH Building Envelope Solutions (2019) table 23 referenced by NZBC Acceptable Solution E2/AS4 (First edition –28 November 2019) on steel-framed buildings, including non-absorbent wall claddings such as vinyl and metal -based weatherboards in direct fixed situations. SOLITEX EXTASANA® Wall Underlay is suitable for use under cavity based wall cladding as an absorbent synthetic wall underlay (type W4) as called up in NZS 2295:2006, Table 2.4 on steel-framed buildings. SOLITEX EXTASANA® Wall Underlay is intended for use as an alternative to conventional building papers which are fixed over timber or steel framed walls in order to limit the entry of wind into building cavities, and to act as a secondary barrier to winddriven rain.

2. The material also provides a degree of temporary weather protection during early construction. However, the product will not make the building weathertight and some wetting of the underlying structure is always possible before the building is closed in. Hence, the building must be closed-in and made weatherproof before moisture sensitive materials such as wall or ceiling linings and insulation materials are installed.

3. SOLITEX EXTASANA® Wall Underlay may also be use as

  • a). a non-rigid backing material for stucco plaster in accordance with the requirements of NZBC Acceptable Solution E2/AS1 (AMENDMENT 10 – 05 November 2020), Paragraph 9.3.5.1 for timber framing or NASH Building Envelope Solutions (2019) Paragraph 9.3.5.1 referenced by NZBC Acceptable Solution E2/AS4 (First edition –28 November 2019 for steel framing, or,
  • b). a slip layer over rigid backings for stucco plaster in accordance with the requirements of NZBC Acceptable Solution E2/AS1 (AMENDMENT 10 – 05 November 2020), Paragraph 9.3.3.1 b) for timber framing or NASH Building Envelope Solutions (2019) Paragraph 9.3.3.1 b) for steel framing

4. SOLITEX EXTASANA® Wall Underlay can be added as a second layer over head flashings in accordance with the requirements of NZBC Acceptable Solution E2/AS1 (AMENDMENT 10 – 05 November 2020), Paragraph 9.1.10.3.
