Gyprock EC08 Impact MR is part of Gyprock’s Commercial Specialty Options range of plasterboards. It is a fire and acoustic rated board designed with high levels of both soft and hard body impact resistance. The board’s core also has moisture resistant additives.
It is low VOC with a high level of recycled content and is GECA accredited making it ideal for high impact risk wet areas in green building projects.
Gyprock EC08 Impact MR is manufactured in Australia to Australian Standard AS2588 and the heavy-duty face paper is a green colour.
The consistently high quality of Gyprock’s products is maintained by a continued focus on quality control and product testing. Internal testing to AS2588 is conducted in a CSR, NATA Accredited Laboratory. Independent specialist testing consultants are also used.
Impact resistant – for high traffic areas
Hard body impact
Hard body impact resistance is generally required where there is a risk of direct impact damage such as in hospital corridors.
For this test, a 50mm diameter steel ball is dropped onto the board from increasing heights until failure occurs. Gyprock EC08 Impact MR provides a high level of hard body impact compared to standard plasterboard.
Soft body impact
Soft body impact resistance is generally an issue where there is a risk of someone falling against or putting pressure against a wall.
To test for soft body impact resistance, a weighted bag (27.2kg) is swung on a pendulum from increasing distances to strike the board sample until failure occurs. Gyprock EC08 Impact MR provides a superior level of soft body impact resistance.
Fire rated – for fire and smoke walls
The BCA/NCC limits the materials used in Class 2 to 9 buildings by controlling the Fire Hazard properties of linings. These properties are assessed using AS/NZS3837 cone calorimeter test. Gyprock EC08 Impact MR satisfies the requirements of the Average Specific Extinction Area standard and achieves a Group 1 rating – the best available.
When incorporated in a recommended Gyprock EC08 system, fire ratings of up to –/120/120 FRL can be achieved.
Acoustic rated – for better sound insulation
The density, or mass of a wall lining material directly affects the wall’s ability to insulate against sound transmission. Gyprock EC08 Impact MR is manufactured to a mass of 12.4kg/m2.
High acoustic rated systems are easily achieved with EC08 Impact MR. Please refer to the Gyprock Red Book® for further details.
Moisture resistant – for wet areas
Gyprock EC08 Impact MR is manufactured around a gypsum core with moisture resistant additives. The face and back linerboards are also treated.
This provides superior moisture resistance and EC08 Impact MR exceeds AS/NZS 2888:1998 Gypsum Plasterboard, for water resistant plasterboard.
GECA accredited – for Green Star building
Gyprock EC08 Impact MR is accredited to the latest Good Environmental Choice Australia 04 – 2011 Panel Boards Standard which is compliant with the requirements of the GBCA’s Assessment Framework for product certification schemes.
When building to Green Star standards, Gyprock EC08 Impact MR meets the required standards needed for Green Star points.
EC08 Impact MR is a non-standard board that can be made available in 13mm thickness in 1200mm wide panels of either 3000mm or 3600mm lengths. The long edges of all panels are recessed for flush jointing.
EC08 Impact MR is predominantly specified for commercial green building projects where a combination of impact and moisture resistance is required.
