PART 3 EXECUTION

3.1 EXAMINATION

Examine substrates and conditions, under which work is to be performed.

Do not proceed until unsatisfactory conditions have been corrected.

1. Review placement area to determine final location will not be within 3 inches of any heat source where the temperature will exceed 180 deg F per ASTM C 411 or in accordance with authorities having jurisdiction.

3.2 PREPARATION

Clean substrates and cavities of loose materials capable of interfering with insulation placement.

3.3 APPLICATION

a. Apply insulation to substrates in compliance with manufacturer's written instructions.

b. Apply insulation to produce thickness required for indicated R Value.

c. Extend insulation in thickness indicated to envelop entire area to be insulated.
