GIB Wet Area Systems
Description

Although able to cope with infrequent short-term exposure, standard gypsum plasterboard will have a shortened life expectancy when frequently exposed to water or moisture. The NZBC does not call for water-resistant linings in wet areas but it is highly desirable to incorporate lining materials which will maintain their integrity longer when exposed more frequently to water or steam and particularly to one-off events such as leakages or flooding of a room.

GIB Aqualine is ideal in such situations because it features a water-resistant wax polymer impregnated core. Unlike other commonly used substrates, the GIB Aqualine core not only resists penetration of water through the lining into the framing behind, but also resists water 'wicking' up the core, a common cause of long-term damage where a water resistant lining has not been used. GIB Aqualine will maintain its integrity for extended periods, particularly where wicking over large areas can destroy the integrity of the interface between the lining and paint or wallpaper surfaces or between the lining and the tile adhesive.

Key Features
  • Water resistant and durable to help protect against water damage
  • Proven substrate for paint, wallpaper, tiles, sheet vinyl and rigid sheet shower linings with installations in over 300,000 bathrooms in New Zealand
  • Suitable for both residential and non-residential applications
  • Dimensionally stable, will not buckle or warp, hence an excellent substrate for ceramic tiles
  • Conventional jointing methods
  • Easy to cut and form openings
  • Contains fibreglass and other additives for strength and fire resistance
  • May be used in GIB Bracing, GIB Fire Rated and GIB Noise Control Systems (see Compliance with the NZBC, Clauses B1, C3 and G6). Consult the appropriate GIB literature for installation details
  • Green face paper for ease of recognition

Scope of Use

GIB Aqualine is ideal in situations where lining materials may be exposed more frequently to water or streams (particularly one-off events such as leakages or flooding of a room) because it features a water resistant wax polymer impregnated core.

Statement of Building Code Compliance
  • Clause B1 Structure: The design and material specification for steel and timber framing used in GIB Aqualine systems must be in accordance with the performance requirements of NZBC Clause B1 (Structure).
  • Clause B2 Durability: When installed and maintained in accordance with this literature, GIB Aqualine tiled or vinyl covered systems have a serviceable life of at least 15 years. They comply with the requirements of NZBC Clause B2 for use in wet areas directly exposed to liquid water, e.g. showers, showers over baths and splash-backs. When used as a general wet area lining and maintained under normal dry internal conditions, GIB Aqualine systems have a serviceable life of at least 50 years and comply with NZBC Clause B2 for use within toilets, kitchens, bathrooms and laundries not directly exposed to liquid water.
  • Clause C3 Spread of Fire: GIB Fire Rated Systems provide passive fire protection in accordance with the requirements of NZBC Clause C3. When GIB Aqualine is substituted into fire rated systems in place of the equivalent thickness GIB Fyreline, the Fire Resistance Rating (FRR) of that system will be maintained.
  • Clause E3 Internal Moisture: When installed in accordance with this literature, tiled or vinyl covered GIB Aqualine systems may be used in areas directly exposed to liquid water, such as showers, to provide an impervious and easily cleaned wall surface.
  • Clause F2 Hazardous Building Materials: At no stage during handling, installation, or serviceable life does GIB Aqualine constitute a health hazard. It therefore meets the provisions of NZBC Clause F2. 
  • Clause G6 Airborne and Impact Sound: GIB Noise Control Systems can be used to provide ratings for Sound Transmission Class (STC) and Impact Insulation Class (IIC) in accordance with the requirements of NZBC Clause G6. 

All GIB unfinished plasterboard sheet materials achieve a Group 1-S interior fire rating to NZBC C/AS2-AS6, Table 4.1, following testing in accordance with ISO 5660.1 and ISO 5660.2.
