PART 3 EXECUTION

EXAMINATION

Verify site conditions under provisions of Section [01039.] [________.]

Verify that substrate, adjacent materials, and insulation are dry and ready to receive insulation.

[Verify that light fixtures have thermal cut-out device to restrict over heating in soffit or ceiling spaces.]

Verify spaces are unobstructed to allow placement of insulation.

INSTALLATION

Install insulation [and ventilation baffle] in accordance with manufacturer's instructions.

[Drill [2] [3] [____] inch ([50] [75] [____] mm) diameter insulation access ports in [facia boards] [soffit panels] [________________] to permit equipment access.]

[Pneumatically] place insulation tight in [stud] [joist] [rafter] spaces.

Place insulation against baffles. Do not impede natural attic ventilation to soffit.

Place tight to and behind mechanical and electrical services within the plane of insulation.

Completely fill intended spaces. Leave no gaps or voids.

[Repair and reseal insulation access ports. Refinish to match existing.]

CLEANING

Clean work under provisions of [01700.] [________.]

Remove loose insulation residue.

SCHEDULES

Existing Exterior Walls:	Pneumatically placed into wall stud spaces through port holes at exterior facia board.

Attic Spaces: Pour insulation between ceiling joists to achieve an R value of 19.
