Scope Showcase Windows, Enlight Industries, LLC requested engineering analyses of their Series/Model 200 single hung window and development of approved window installation methods. Specifically, the analyses are to determine the quantity and spacing of anchors for the single hung window referenced in Construction Consulting Laboratory, International Report 05-130 (H-R40 44 x 84). Calculated anchorage requirements are based on Spruce-Pine-Fir framing and utilize the methods of the National Design Specification for Wood Construction, ANSI/AF&PA NDS-2005 (AFPA/AWC, 2005). Also, installations to hollow CMU, concrete and steel stud are evaluated. All windows are assumed to be fastened through frame (replacement installation). Analyses

Test Results Unless noted otherwise, testing was conducted to ANSI/AAMA/NWWDA 101/I.S.2-97 Voluntary Specifications for Aluminum, Vinyl (PVC) and Wood Windows and Glass Doors at the construction Consulting Laboratory, International test facility in Carrollton, Texas. Specimen size and results are summarized in the following table. Table 1 Summary of Test Results

Test Report Report Date Overall Size Achieved Rating CCLI-05-130 10/14/05 44" x 84" H-R40 44 x 84



Anchor Capacity Individual anchor capacities are based on a through-frame installation (single shear) into three substrates: Spruce-Pine-Fir wood framing, concrete and hollow CMU construction and steel stud. Calculations are presented on Page 4 through Page 7 and summarized in Table 2. Table 2 Calculated Anchor Capacities

Substrate Anchor Capacity (lbs) Comments

Spruce-Pine-Fir #8 Wood Screw 107

1. Limited by bending capacity of anchor

2. 1-3/8" penetration into wood required

Hollow CMU and Concrete 3/16" Tapcon 185


2. Minimum 1-1/4" embedment 3. Minimum 2" edge distance

Steel Stud #12 TEKS 110


2. 18 gauge 33 ksi stud minimum required

3. Penetrate screw 1/4" beyond drill point

Required Anchors The overall window dimensions, established design pressures published in the referenced test report and the calculated anchor capacities are used to determine the minimum anchor spacing and number of anchors required to resist the design wind loads. Calculations are presented on Page 8. Based upon minimum anchor requirements, as-tested anchorages and typical installation practices, required anchor locations are presented in the attached drawings.
