1. Design wind pressures shown are for 30' mean roof height, effective wind area of 10 sq. ft., wall corner zone 5. For other conditions, see ASCE 7-10 Table 30.5-1
Table 3: General Wind Pressure Resistance Criteria per ASCE 7-10 for Components & Cladding, Method 1
5.6. Example for use of the tables in this TER
Given the following:
Wind Speed, V
ult
= 180 mph
Exposure D
Mean roof height 25'
Concrete construction with 2" continuous insulation (CI)
Locate the appropriate fasteners in Table 1. Many will work with 2" CI.
The corresponding wind pressure from Table 3 shows that this installation corresponds to an allowable wind
pressure of 125.6 psf.
Verify the withdrawal value of fasteners in Table 2.
Either the
3
/
16
" or ¼" Tapcon Hex screws will provide both sufficient shear and withdrawal for this example.
6. Installation:
6.1. General
6.1.1. Versetta Stone
®
shall be installed in accordance with the manufacturer's installation instructions and this
TER. In the event of a conflict between the manufacturer’s installation instructions and this TER, the more
restrictive shall govern.
6.1.2. Installation is subject to the conditions of use set forth in Section 9.
6.1.3. All Versetta Stone
®
vertical joints shall be staggered between courses.
6.1.4. All other installation and flashing details germane to the project shall be in accordance with the applicable
building code, the building designer's details and the manufacturer’s installation instructions.
6.2. Concrete and Masonry Walls
6.2.1. Versetta Stone
®
shall be installed over walls capable of resisting 100% of the design wind loads and shall
be attached, at a minimum, in accordance with Table 1.
6.2.2. Versetta Stone
®
may be installed with (an) intervening layer(s) of continuous insulation and attached in
accordance with Table 1.
6.2.3. Each Versetta Stone
®
panel shall be installed with a minimum of three (3) fasteners as follows:
6.2.3.1. Two (2) of the fasteners must be installed into the concrete or masonry at each end of the panel and
have a minimum penetration depth as shown in Table 1.
6.2.3.2. The other fastener must be installed into the concrete or masonry at the center of the panel.
6.2.4. Fastener sizes shall be in accordance with Table 1 or generally accepted engineering practice.
6.2.5. A water-resistive barrier (WRB) is not required in this application; however, a WRB is permitted and may
be mechanically attached, liquid applied or taped FPIS seams.
7. Test and Engineering Substantiating Data:
7.1. Reports showing compliance with ASTM C1185 for evaluation of moisture movement through the product as
well as nail hem bond strength.
7.2. Reports showing compliance with ASTM C1186 for the physical and mechanical properties of the product.
