(iii) Medium Density Fiberboard (MDF) Performance of glass façade in scenario of internal fire spread is evaluated through test 4.
Toughened glass of 1200mm x 400mm and 6mm thickness are attached to the aluminium
framework fixed between concrete beam and masonry wall at either ends. Figure 13 shows
Performance of glass panel along with Medium Density fiber board under fire is the framing layout for Test 4.
evaluated in test 3. MDF is typically made of 82% wood fiber, 9% urea-formaldehyde
resin glue, 8% water and 1% paraffin wax with a density between 600 and 800
kg/m3.
MDF panels of 6mm thickness with exposed side painted with oil paint color were
used. MDF panels are fixed to cladding framework in a similar manner as glass
panel. 60% Glass and 40% MDF is used in comprising the whole assembly. Figure 12
shows the layout of framework for glass and MDF panel assembly under test.
