AUGREEN block wall system is awarded HK G-PASS PLATINUM by HKGBC, which is the first desulfurized gypsum for commercial use & certificated the Green Council Green Label Award, AUGREEN Block System is among the very few wall partitions which meets users demand for flexibility and versatility in Hong Kong.

AUGREEN Blocks act as natural air quality regulators to maintain comfortable indoor temperature and relative humidity. AUGREEN Blocks are integrated solution for fulfilling various requirements such as high quality of products and services, shorter project time, lower costs, safer sites, better appearance, faster and easier installation and simpler coordination.

Light Weighted

Gypsum is a light-weighted material that weighs less than half of the weight of cement, making AUGREEN Block Wall System easier to be transported. The total dead load of a 20-story building is estimated to be over 1,000 tonnes less than a cement building.

Space Saver

AUGREEN Block Wall System is made to be light and thin, compared to a 100mm-thick concrete wall with 2 layers of 15mm-thick plastering, AUGREEN Block Wall System saves 55mm with a 75mm-thick wall which is beneficial for space enlargement to users.

Tough and Strong

No steel stiffener is required for 7m or below high 100mm-thick AUGREEN Block Wall System. No door / opening lintels are required for openings which are less than 2-metre wide.

Sound Insulation

AUGREEN Block Wall System is sound-proofed; an 75mm-thick AUGREEN Block can achieve an equivalent sound insulation performance of a 100mm-thick concrete wall.  AUGREEN EQ system has improved from the traditional block wall and drywall system limitation. For 153mm thickness AUGREEN EQ55 system, the noise insulation up to STC55 could be achieved.

Fire Resistance

Safety is one of our first priorities. Our 75mm and 100mm AUGREEN Block Wall System have passed the 2 hours and 4 hours Fire Resistant Poly (FRP) test respectively.


Quick Installation

AUGREEN Block Wall System is movable-friendly due to its size and light-weight features, and is easy installation. The installation time of AUGREEN Block Wall System is 50% faster than installing concrete blocks which require plastering, steel framing and rubbish handling. 15-20m2 can be built per man daily and painting can be started 2-3days after the installation of AUGREEN Block Wall System.


Being as the 1st wall partition brand in Hong Kong, AUGREEN Block Wall System is honored to win numbers of sustainability awards including the "Merit Award" of Building Product Section of Green Building Award 2012 and the "Green Innovation Awards" of Hong Kong Awards for Environmental Excellence (HKAEE).


Benefiting from the high strength of AUGREEN Block Wall System, it is flexible to be decorated in any style as user’s desire. AUGREEN Block Wall System has a shear force of 1.4kN. Each plastic anchor can bear 100lbs and each metal screw can bear 200lbs.
