3. Fasten insulation anchors to substrates. Space anchors according to insulation manufacturer's written instructions for insulation type, thickness, and application indicated.

4. Install board insulation by pressing insulation into position over spindles and securing it tightly in place with insulation-retaining washers.

C. Framing cavity insulation:

1. Use insulation widths and lengths that fill cavities formed by framing members. If more than one length is required to fill the cavities, provide lengths that will produce a snug fit between ends.

2. Provide a friction fit between edges of insulation and adjoining framing members.

3. Maintain 3-inch clearance of insulation around recessed lighting fixtures not rated for contact with insulation.
