-
- 3.2 PREPARATION
-
- A. Follow manufacturer's instructions for allowing panels to
- be exposed to environmental temperature and humidity
- conditions for not less than 24 hours before start of
- installation.
- NOTE ** Burlap is a natural fabric and can vary in shade
- between production runs. Before installation,
- Burlap Panels should be positioned in place to
- ensure that desired appearance is obtained. Delete
- the following paragraph if Burlap Panels are not
- specified.
-
- B. Temporarily position Burlap Panels in place and request
- Architect's approval, to ensure that desired appearance
- is obtained.
-
- 3.3 INSTALLATION
- NOTE ** Homasote specifies framing at 16 inches (400 mm)
- o.c. for all installation methods except over
- finished walls; panel edges and ends are required
- to align with framing members or be blocked for all
- methods. Verify that appropriate framing section
- or drawing notes comply. Special framing may be
- required if panel joint layout is defined.
- NOTE **
- NOTE ** Furring for masonry or concrete walls can be one-
- by's (19 mm) wood or standard hat-shaped metal
- furring channels. Specify furring in the
- appropriate wood or metal framing section.
-
- A. Follow manufacturer's instructions for cutting and
- installation of panels:
- NOTE ** Installation is dependent on substrates; select
- from the following subparagraphs accordingly,
