(i) Glass

The common material under performance evaluation for
all tests is glass. Test 1 involved local market glass whereas (ii) Aluminium Composite Panel (ACP)
tests 2, 3 and 4 involved standard glass. Standard glass was

mm thickness fixed to the aluminium cladding framework polyethylene core laminated and sandwiched
through pressure tapes and silicon sealant as binder gel. between two fine aluminium sheets. ALU DÉCOR AL
Technical specifications of glass under testing are as 45 ACP sheets are used in combination with local
follows: 58 x 64mm. Aluminium Section Frame ( Center) glass for test 1 whereas ACP sheets are combined

with Saint gobain toughened glass for test 2.
Fire Stop Material
• Thermal shock resistance: Upto 250°C ACP sheets are of size of glass panels (1200mm x
• Mechanical strength: four to five times stronger 400mm) with thickness of 4mm and is fixed to the
aluminium framework in a similar manner as glass
than annealed glass 6mm Glass Deck Slab panels.Figure 11 shows the aluminium framing

• Tensile strength: 65 MPa layout for fixing ACP sheets and glass panels. 60%
• Bending strength: 120-200 N/mm2 150 glass and 40% ACP sheets comprises the whole test
• Surface compression: >95 MPa assembly.
• Design stress for architectural purposes: 50 MPa Silicon Core material for ACP sheets under test consists of
• Fragmentation: Small round crystals Hollow Space virgin Low Density Polyethylene (LDPE). Panel

• Conducive for processing 6MM X 6MM Pressure Tap weight is 5.5 kg/m2 and thermal expansion
• Cannot be cut after toughening coefficient is 24 x 10-6/°C. Other detailed technical
