COMPARISON BETWEEN BRICKWALL AND JOE GREEN PANEL
CONCRETE IS LONGEST LASTING MATERIAL – BRICK WORK MAY SPIDER CRACK OVER TIME DUE TO SETTLEMENT (HEAVY) & THERMAL EXPANSION (RETAIN HEAT)

DURABILITY
COMPARISON BETWEEN AAC BLOCK SYSTEM AND XS JOE GREEN PANEL
i. USE IN HIGH RISE
Not suitable for high rise as external wall, cracking after 5 stories observed due to Low Compressive strength of product (+-5.5Mpa)
ii. ON FINISHING
Requires thick Plaster, if not spider cracks will emerge due to high water absorption of product. Further, the Motar is Higher compressive strength than Block (12-20Mpa versus 5-7Mpa). Any slight loading transfer will cause block to crack.
iii. ON MOUNTING FIXTURES Not recommended due to very low compressive strength of product (5.5Mpa). No Strength and Porous due to foaming agent.
iv. M&E INTEGRATION
Product cannot be hacked or chased, will disintegrate due to no strength. M&E installation external.
v. EXTERNAL USE
Not recommended due to product porosity. Easily observed spider cracking and water seepage.
vi. IN WALLS DESIGN Requires Lintel and Stiffener every 3x3m.
Suitable for use due to High Strength (40Mpa ++) and benefits with proper detailing.
Requires Skim Coat only due to product flatness tolerance of +-3mm (for 3 meter height panel) and very low water absorption.
(6.41% on 24 hour immersion test)
Very strong panel design (40Mpa), Direct mounting of Kitchen Cabinets and Toilets, etc on JOE Green panel OK. (400KG /point Load)
Easily integrated into hollows. M&E Team can start work the next day from installation.
Compact and strong panel with Very Low water absorption, used widely as external wall.
Customisable to 6.5m. Minimum use of Lintel & also Stiffener.

Considerations & Limitations
RC Wall using Wood Formwork
1. Speed/Productivity Tedious and slow
Faster due to the customized modules, but still requires time for assembly, input of rebar, concreting, curing and unassembly. (Minimum 4-5 days for whole process.)
2. Straightness of Wall Warping will occur if wrong thickness of Wood form used, secured wrongly, overused too many times.
Immediate, with M&E works able to come in next day after panel secured top and bottom.
3. Thickness of wall RC Walls minimum 150mm due to the rebars.
Warping will occur if moulds are kept incorrectly, need to be serviced at intervals to ensure that no warping-service downtime to be considered.
RC Walls minimum 150mm due to the rebars.
JOE Panel straightness is ensured SUPERFLAT- at <3mm per 3 mrun of wallaccording to CONQUAS and QLASSIC standard.
JOE Panel’s 75/80/90mm gives one hour fire ratings whereas 100mm provides 2 hours fire rating- allowing for more floor space while providing better Sound Transmission Coefficient (STC) and Fire Rating.
4. Finishing of wall May have Honeycomb due to insufficient or over vibration of concrete.. Smooth, need Spatterdash for tiling
May have Honeycomb. Smooth, need Spatterdash for Tiling
Superflat, and surface devoid of moulding oil commonly observed in formwork- able to directly apply tile.
