• Fire resistance
• High acoustic performance
• Impact resistance
• Water resistance

16mm Multistop™ 4 is an ideal solution for projects demanding multiple requirements from the internal linings incorporating Fire, Impact, Sound and Water resistance. Multistop™ 4 is suitable for a wide range of wall and ceiling applications, ideal for hospitals, schools and environments where a multiperformance board is required.

16mm Multistop™ 4 was fire tested and certified by BRANZ to meet the requirements of the National Construction Code (NCC).

16mm Multistop™ 4 contributes to the Fire Resistance Level when used in fire-rated systems. Refer to Technical Bulletin for details and limitations Fire tested to achieve the least fire hazard Group Number for wall and ceiling materials as defined by NCC (BRANZ report No. FH 15783).

16mm Multistop™ 4, when used in an acoustic system can provide required levels of sound insulation to achieve specified acoustic ratings.

16mm Multistop™ 4 complies to relevant deem-to-satisfy provisions of BCA Specification C1.8 Structural Tests for Lightweight Construction.

Exceeds compliance criteria for NCC resistance to impact test to ASTM E695-03.

Exceeds compliance criteria for NCC resistance to static pressure test to ASTM E72-15.

16mm Multistop™ 4 is manufactured to exceed water resistant grade gypsum plasterboard requirements of AS/NZS 2588: 2018 Gypsum Plasterboard.

Meets deemed to comply requirements of the NCC and AS 3740:2021 Waterproofing of domestic wet areas when installed to Knauf plasterboard wet area installation details.

Knauf products are manufactured from a combination of natural gypsum, and paper liner made from 100% reclaimed and recycled paper waste. Plasterboard waste can be reclaimed and recycled into new plasterboard. Lightweight plasterboard construction offers the benefits of low embodied energy, non-toxic materials, enhanced indoor air quality, and ease of thermal and acoustic upgrading.
