PermaBase

brand Cement Board

Cement Board Stucco

Wall System (CBSS)

Combine the strength and durability

of PermaBase with the performance

and aesthetics of reinforced base

coats and textured finishes. Use in

residential and low-rise commercial

applications.

Cement Board Stucco Wall

System is designed to:

Provide increased impact and

weather resistance (appropriate

for all climates)

Resist dirt, fading, cracking and

peeling – uses 100% acrylic

polymers

Speed up your schedule –

easier, cleaner installation than

traditional stucco

Provide drainage system to help

prevent water from penetrating

behind cladding in frame

construction

Engineered system that allows a

faster installation while providing

superior quality control (manufac-

tured product that must comply

with ASTM product specifications).

Provides a 15-year limited exterior

warranty – the industry's best

Designs you can achieve

with this system:

Attachment of special pre-

molded shapes

Variety of finishes – many texture

and color options

Limitations

Treat joints in PermaBase with

mesh tape and base coat

Thin veneer construction can

reveal planar irregularities in

framing

Minor cracking at joints may

Continuous

Insulation

As building codes and building

insulation requirements become

increasingly stringent, you can

count on PermaBase to help

meet your substrate needs for

Continuous Insulation (CI). CI on

the exterior envelope helps to

eliminate air and moisture leakage

as well as reduce thermal bridging,

or the heating/cooling loss

transmitted through steel studs.

Methods to install the final exterior

finish over the exterior insulation

are now being refined, including

z-furring channels, batten strips

and direct fastener applications.

Use in all types of construction,

including commercial, residential

and multi-family.

Advantages Of Creating

Continuous Insulation With

PermaBase:

Provides better thermal comfort,

lowers heating and cooling

costs, reduces likelihood of

trapped moisture

Helps mitigate the loss of heat/

air conditioning by insulating

the studs

Allows multiple finishes on one

substrate

Works in all climates – adapt-

able to varying regional system

requirements

Guarantees 15-year exterior

warranty – the industry’s leading

warranty

Speeds up your schedule –

faster to install than traditional

methods

Engineered system that allows

a faster installation while pro-

viding superior quality control

(manufactured product that

must comply with ASTM

product specifications)

This section of the PermaBase Exterior Applications Guide provides infor-

mation on how to utilize PermaBase within both a CBMV System and a

Continuous Insulation System. While some typical examples are shown

for reference purposes, the specifications on how to design and construct

individual systems should be obtained from the adhering material or veneer

manufacturer of the materials being used to complete the system.
