CB4 CONDENSATION BOARD

INSTALLATION GUIDELINES

How to install on sidewalls.

Install GreenGuard

CB4 vertically or horizontally on a

sidewall using the following steps:

A. To install vertically

1. Measure the length of sheet

required and pre-cut each sheet

to the desired length.

2. Install each sheet starting with

attachment at the top of the wall

and proceed down the wall.

3. Use

" staples or self-tapping

screws (for metal framing) to attach

CB4 to the girts, with spacing at approximately 12" on center.

B. To install horizontally

1. Snap a chalk line along the length of the wall to establish a

straight edge before installing the first course of CB4. The line

should be positioned so that approximately 3" of it extends

below the top of the foundation.

2. Attach the board by starting with the first course at the lower

corner with the first 2' x 4' panel wrapped around the corner.

The top edge of CB4 should be aligned with the chalk line,

resulting in a 3" overlap of the foundation.

3. Unfold the bundle to the right along the wall to the adjacent

corner. Install the upper course(s) once the first course has

been installed.

4. Use

" staples or self-tapping screws (for metal framing)

to attach the board to the girts, with spacing at approximately

12" on center.

5. Continue to work along the wall, attaching the board while

unfolding the bundle or pre-cut sheet.

6. Tape the seams using the steps under the “How to Tape

Seams” section.

How to install on the bottom side of roof

trusses.

1. Measure the distance from

the top edge of the wall to

the roof ridge and cut a sheet

of CB4 to the desired length.

2. Attach CB4 to the bottom of

the rafters or purlins using

staples or self-tapping screws

(for metal framing) spaced approximately 12" on center.

3. Continue installing adjacent courses of CB4 parallel to the

previous courses.

4. Tape the seams using the steps under the “How to Tape

Seams” section.

How to install over roof

purlins.

Install GreenGuard CB4 parallel or

perpendicular over roof purlins using

the following steps:

1. After trusses are set, make a final check to ensure that the

trusses have not been pulled out of line.

WARNING: The CB4 surface can be slippery, so care should be taken when standing or

walking across it. Appropriate safety precautions for working on roofs should be taken to

prevent falls.

2. Start at one end of the roofing framework to begin installation

of the CB4 sheets. CB4 can be installed using one of the

following methods:

A. To install parallel to the purlins CB4 is designed to allow for all

seams to be aligned with purlin locations so that no seams are

visible from the building interior. The 4' width of CB4 is attached

to the purlins that run parallel to the roof ridge (typically spaced

either 2' or 4' apart). CB4 can be attached to wood purlins using

staples that penetrate the purlin a minimum of

" or can be

attached to metal purlins using minimum

" long self-tapping

screws. The seams on the top, green side of CB4 can be

overlapped or butted together and taped to prevent

condensation. (Contact Pactiv Building Products for a list of

acceptable tape products.)

B. To install perpendicular to the purlins, CB4 is installed by

aligning the sheets perpendicular to the purlins so that the

length of the sheet extends toward the roof ridge and each CB4

fold is located on a purlin (every 2'). CB4 can be attached to

wood purlins using staples that penetrate the purlin a minimum

" or can be attached to metal purlins using minimum

long self-tapping screws. The seams on the white, interior side

of CB4 can be overlapped or butted together and taped to

prevent condensation. (Contact Pactiv Building Products for a

list of acceptable tape products.)

3. Continue working along the roof, installing consecutive CB4

sheets parallel to adjacent sheets, making sure that all seams

are overlapped or butted together and taped. (Refer to the

“How to Tape Seams” section.)

IMPORTANT: Use caution when walking across the roof where CB4 has already been

installed, taking care to step on supported locations only. (Use fastener penetrations as

a guide or use a chalk line to indicate supported locations.)

How to tape seams.

1. All CB4 seams should be butted together. Contact Pactiv

Building Products to obtain a list of approved tapes.

(DO NOT USE DUCT TAPE.)

2. All surfaces should be clean and dry prior to installing the tape

in accordance with the tape manufacturer’s instructions. Use

a tape width that is sufficient to cover the seam between

adjacent sheets.

3. When applying the tape, use a squeegee or other flat edge tool

to press the tape against the CB4 to ensure a tight seal.

Taping seams may not always be necessary in buildings where

condensation is not a concern. Overlapping edges or installing

edges behind girts or purlins is sufficient. But, in buildings used to

house animals or to store food, seed, or vegetables, the humidity

is higher and taping seams is recommended.
