LOCATIONS USING URETHANE FOAM AND FOAM MATERIAL
1. Urethane foam is inserted into the center pillar to prevent the penetration of noise.
2. By filling the top of the front pillar, bottom of the front pillar, center pillar, side roof rail, rear pillar
and inside the wheel house arch with foam acoustic material, penetration of noise is prevented.
Precautions on performing work involving sheet metal at locations using foam material
As foam may burn when heated, observe the following precautions.
1. Do not perform heating work using gas burners at locations using foam material.
2. When cutting locations using foam material, use tools (air saw, etc.) which do not generate
heat.
3. If leftover foam material is present at the area to be cut (body side), remove the foam around
the area to be welded before proceeding with welding.
