<br />. <br />~ <br /> <br />Architectural Testing <br /> <br />15 April 2002 <br /> <br />Mr. Marsh Fembaugh, Director of Testing <br />Alside, Window Company <br />3773 State Road <br />Akron, Ohio 44309-1365 <br /> <br /> <br />RE: Masonry Installation of 0201 Double Hung Window, 3' 0" by 6' 0" <br /> <br />Dear Mr. Fembaugh: <br /> <br />At your request, I have performed an installation fastener analyses into masonry <br />block walls for Alside double hung windows, Model 0201. The testing of the actual <br />windows was done under AT! project 05-30324.02. The fastener analyses provides a 3' <br />0" wide by 6' 0" high window with an allowable installation design wind pressure (D.P.) <br />of +/- 55.0 psf. <br /> <br />To provide this D.P. in a masonry block wall requires 6 Tapcons, each 3/16" in <br />diameter. There should be 3 Tapcons through each window jamb frame, one near the top, <br />one at the midheight, and one near the bottom. The minimum penetration of the Tapcons <br />into solid masonry must be 1-1/4". <br /> <br />These results are appropriate for the size window stated in the first paragraph <br />above, and any size smaller. If there are any questions about this analyses, please advise <br />me. <br /> <br />Sincerely yours, <br /> <br />ARCHITECTURAL TESTING, INe. <br /> <br />~ <br /> <br />t2L4." n, ~ <br />Allen N.
