2. Pack insulation around door frames and windows, in building expansion joints, door soffits, and other voids.

3. Pack behind outlets, around pipes, ducts, and services encased in walls.

4. Hold insulation in place with pressure sensitive tape.

5. Lap facer flanges together over framing for continuous surface. Seal all penetrations through the insulation and facers.

6. Do not compress insulation below required thickness except where embedded items prevent required thickness.

B. Semi Rigid, Batts and Blankets:

1. When insulation is not full thickness of cavity, adhere insulation to one side of cavity, maintaining continuity of insulation and covering penetrations or embedments.

a. Wood Framing:

1) Fasten blanket insulation between wood framing and joists with nails or staples through flanged edges of insulation.

2) Space fastenings maximum 150 mm (6 inches) on center.

b. Metal Framing:

1) Fasten insulation between metal framing with pressure sensitive tape continuous along flanged edges.

2) At metal framing or ceilings suspension systems, install blanket insulation above suspended ceilings or metal framing at right angles to the main runners or framing.

3) Tape insulation tightly together so no gaps occur and metal framing members are covered by insulation.
