Fire Test 2

Materials used: Hard Plywood Board
Date: May 2014

Test Setup:​

• 2 identical staircases (hard plywood board, 25mm/1”)

• Each staircase has 9 steps

• Each step is 17cm/6’7” high and 35cm/13’8” deep

• The staircase is 1.23m/48.4 wide

• One of the staircase is protected with akuSta-Plast Fire Stop (only bottom is covered), One is unprotected

• The temperature is measured using a thermometer located on top of the 4th step

Fire Test 3

Test #1

1. Top: Roofing (4mm/0.15”)

2. Bottom: Hard plywood board

​Results:

• Roofing melts & burns

• Toxic substances are released

Test #2

1. Top: Roofing (4mm/0.15”)

2. Middle: akuSta-Plast Fire Stop (2.5mm/ 0.08”)

3. Bottom: Polystyrene

Results:

• 2.5mm/ 0.08” of akuSta-Plast Fire Stop reduce the temperature from 1,200 C to 200 C

• Polystyrene starts burning at a much lower temperature than roofing. Thanks to akuSta-Plast Fire Stop the temperature remains far below the ignition point.

Test #3

1. Top: Hard plywood board (20mm/0.8”)

2. Middle: Hard plywood board )20mm/0.8”) protected by akuSta-Plast Fire Stop (2.5mm/ 0.08”)

3. Bottom: Hard plywood board )20mm/0.8”)

Results:

• The unprotected hard plywood board loses its structural integrity within seconds. A wooden staircase would be completely unusable.

• A wooden staircase protected by akuSta-Plast Fire Stop could still be used during evacuation or fire fighters entering the building.
