<br />I <br />.. <br />~ <br /> <br />Architectural Testing <br /> <br />March 26, 2003 <br /> <br />Marsh Fernbaugh, Dire~tor of Testing <br />Aiside Window Company <br />3773 State Road <br />Cuyahoga Falls, Ohio 44309-1365 <br /> <br />.KE: Alside 0201 Vinyl Double Hung Wmdow (3' 0" wide by 6' 0" tall) Installed to <br />Wood Framing <br /> <br />Dear Mr. Fernbaugh. <br /> <br />I have performed an installation fastener analysis for your 0201 double hung window <br />installed to wood framing, The window size considered was 3' 0" wide by 6' 0" tall. The <br />design wind pressure for this window, as determined by the testing documented in ATI <br />Test Report 05-30324.05, is +/- 55.0 PSF. <br /> <br />My analysis assumed using #8 wood screws with a minimum penetration to the wood <br />framing of 1-1/4". The wood framing must be Spruce-Pine-Fir with a specific gravity of <br />G=0.42 or better. To safely resist the design wind pressure of the three sizes considered, <br />6 such screws are required. At installation, use three screws in each jamb: one near the <br />top corner, one near midspan and one near the bottom comer. <br /> <br />This installation detail is appropriate for smaller windows of this model subjected to the <br />same design wind pressure. If you have any questions regarding my analysis, please <br />contact me. <br /> <br />Sincerely, <br /> <br />ARCHITECTURAL TESTING, INC <br /> <br /> <br />JAR:jar <br /> <br />cc: <br /> <br />05-30324.05 <br /> <br />.<~"~,,,,<_,.,.,,\~,,'."Ii":';, "/," "" <br /> <br />. . . ~ . :, ::-..... <br />:~'~.,.....: ".' ..
