2.0 USES

Plycem USA’s Allura™ fiber cement lap and panel

products are intended for use as exterior wall coverings

and soffits.

3.0 DESCRIPTION

Allura™ products are autoclaved, single-faced wall

coverings manufactured from a proprietary mixture

of cellulose fiber, portland cement, silica, clay or fly ash

and limestone. See Table 1 for dimensions and surface

texture. Design wind pressures must be determined in

accordance with the applicable code. See Table 2 for

allowable wind pressures, fastener schedules, and

installation requirements. Wind pressures noted in Table 2

are allowable values for positive and negative directions.

Allura™ fiber cement sidings exhibit a flame-spread

index of 25 or less and smoke-developed index of 450 or

less when tested in accordance with ASTM E84.

Allura™ fiber cement is classified as non-combustible

when tested in accordance with ASTM E136.

Allura™ lap and vertical panel siding products are

recognized in this report as components of a one-hour,

fire-resistance-rated, limited-load-bearing, wood-stud wall

assembly, when installed in accordance with Section 4.7 of

this report.

Lap siding, vertical panel siding, soffit panels and

shapes siding come in lengths and widths as noted in

Table 1. All edges are square. Shapes siding is a panel-

type product available with various designs.

The attributes of the stone veneer have been verified

as conforming to the requirements of (i) 2013 CALGreen

Section A4.405.1.3 for prefinished building materials

and Section A5.406.1.2 for reduced maintenance; (ii)

ICC 700-2015 and ICC 700-2012 Sections 601.7,

11.601.7, and 12.1(A).601.7 for site-applied finishing

materials; and (iii) ICC 700-2008 Section 601.7 for

site-applied finishing materials. Note that decisions on

compliance for those areas rest with the user of this report.

The user is advised of the project-specific provisions that

may be contingent upon meeting specific conditions, and

the verification of those conditions is outside the scope of

this report. These codes or standards often provide

supplemental information as guidance.
