Course Objectives

• Describe how rainscreen cladding systems work to reduce

moisture penetration on a building’s envelope.

• Define Exterior Grade Phenolic (EGP) and explain the

manufacturing process.

• Analyze Third Party performance criteria for EGP and describe the

evaluation methods of the three tests most commonly required by

building codes.

• Observe how EGP can be fabricated and explain proper methods

for handling and storing EGP panels.

• Examine and discuss installation practices for EGP and identify

incorrect installation methods that could compromise the

effectiveness of a rainscreen cladding solution.

• Observe various types of projects where EGP has been

successfully used. 4

What Third Party Testing

Standards Apply to EGP?

What is an Evaluation Report (ER)?

• “ER sometimes referred to as code reports, created

to either evaluate products or methodologies that are

not explicitly addressed by the current code (or

earlier) building code…”

and Implementation of Acceptance Criteria and Product Evaluation Repots

What is an Acceptance Criteria (AC)?

• “AC are documents that state the requirements for a

which a product is evaluated in order to demonstrate

code compliance.”

How to Handle EGP

Shipping EGP

48

49

When removing EGP panels from pallets,

each panel should be lifted directly up. Do

not slide panels off of the stack as sliding

may scratch or damage the panels.

50

• EGP panels should be

stored horizontally on

shelving that enables

the panels to lie flat and

provides complete

support.

• A weighted panel

should be placed on top

of the panels if stored

for an extended period

of time.

• Do not stagger panels

and ensure that panel

edges do not hang over

the rack edge.

51

• When transporting

panels to job site, make

sure the panels are

properly packaged,

strapped and protected.

• Use cardboard under

strapping to ensure the

strapping doesn’t

damage the panels.

• Use corner guards to

further protect the

panels.

• Do not store panels

outside for any

extended period of

time.

52

Never store EGP panels

vertically as this may

damage panels.

For temporary storage outside,

cover the panels well to protect

them from climatic elements and

to avoid moisture penetrating and

accumulating between the panels.

Parameters to Keep in Mind with EGP

• EGP panels are secured to vertical channels that are anchored to the

inner wall, typically with the use of exposed screws.

• Joints are left open so the movement of the panels is never restricted.

• Since moisture will make its way to the inner wall, a moisture and/or air

barrier will be needed. Consult your “barrier” representative to

specify the correct type for your local geographical area and

building requirements.

• A minimum 1” air space must be left between the back of the EGP

panel and the inner wall to enable the air movement required for the

cavity to dry. 73

Required panel installation gap

Panels can not be

installed in a manner in

which the panel is

bridging a gap between

adjacent typical profiles

Why Stainless?

• Corrosion on the head can

cause rust streaks.

• Corrosion of the

threads/shank can cause

safety issues.

• Corrosion of the head can

cause pull-over problems.

Panel Direction

• Panels have a Top &

Bottom.

• Manufacturers will

clearly note this by

placing arrows on the

protective film.

• Panels that are inverted

during installation may

appear to have shading

differences, called the

“Sunrise/ Sunset effect”.81

Graffiti Resistance

• No preventive anti-graffiti treatment is necessary.

• Spray paint or Sharpie® pens can typically be

removed with a solvent-based cleaner.

Protective Film

Panels may be shipped with a

protective film by manufacturer

• The purpose of the protective film is

to protect the material during

storage and shipping.

• Panels should be inspected under

the film for any visual defects before

fabrication and installation.

• Typically the contractor will only be

reimbursed for the cost of the un-

fabricated/installed panel. 150
