- Stable compact walls with high resistance against mechanical loads
- GREENTECH Gypsum block walls can be built up to 9m in height without steel frames
Carry Heavy Marble
Gypsum block walls can be built > 7m wall in height without steel frames
Water Repellent
- Hydrophobic GREENTECH Gypsum Block
- H1 level of water adsorption (BS EN 1285): <2.0% by weight of water absorption capacity is resulted when gypsum block is immersed in water for 2 hours.
- Applicable for wet area including kitchens, washrooms and places with high humidity expectation.
Regulates Room Temperature and Humidity
- Low thermal conductivity to keep the room temperature cool.
- Acts as a natural air conditioner to adjust indoor temperature and humidity.
- Lower energy consumption on air conditioning and dehumidification.
Fire Resistance & Thermal Insulation
- Non-combustible
- Compliance with BS EN 1364-1:1999: achieve a fire rating of 240-300mins in both integrity and heat insulation
- 75/80mm thickness – 180mins 100/150mm thickness – up to 300mins

Average and maximum temperature rise of specimen over the test period
- Provide excellent fire protection
- Able to fulfill high fire protection requirements for areas such as basements and plant rooms
Sound Insulation
- Can achieve up to STC-60 sound insulation.
- Special designs are available for areas requiring even higher acoustic performance.
High Construction Efficiency
- The large format and tongue & groove design of GREENTECH Gypsum Blocks speed up wall construction time.
- A smooth surface allows construction to proceed with precision and evenness.
- Flexible E&M construction saves time and cost for construction.
Tongue & Groove Design
- Tongue & Groove design of GREENTECH Gypsum Blocks speed up the wall erection time.
- Simple tools for MEP services installation after wall construction.
Flexible MEP Services Installation
GREENTECH Gypsum Block Walling Systems also allows the use of simple hand tools to form grooves and openings for MEP services to be installed after the gypsum block walls are erected. Form engineer’s point of view, it is flexible for E&M construction. This saves critical time and cost for coordination and construction.
Door and Window Frame Installation
Time & Cost-Effective
- Plastering and steel stiffener are not required for GREENTECH Gypsum Block
– Save subsequent cost including labour, materials, transportation.
– Reduce Construction time and wastage
- Elimination of cement-based plastering works also saves site clearance cost, simultaneously providing a safer and cleaner working environment.
