ADVISORY AND MEMORANDUM TO AAF GUIDE USERS ABOUT CONTINUING UPDATES:
The AAF Guide contains a large number of tables. Changes in industry practices and available products effect the use of the AAF Guide as a reference. Additionally, changes to the Florida Building Code may also effect provisions in the Guide. In this section we will try and address all of these issues in a timely fashion.
A case in point is the introduction of higher strength alloys into the Florida market. 6005T5 alloy and 6061T6 extrusion products became available after the completion of the 2007 edition. Chapter 1 (Screen Enclosures) tables were re-done to fill this gap and are available as per Technical Bulletin #1.1 below. For your information, there are 72 screen roof beam tables (for each wind Exposure Category), considering varying wall heights, wind zones and enclosure types. So, for both exposures (B & C) and both available alloys, this results in 288 roof beam tables to consider all of the permutations.
The AAF sponsored a code amendment during the Glitch Cycle (2009 amendments to the Florida Building Code) permitting a design pressure reduction for the use of 18/14 mesh screen. New added tables are under construction to provide data for this provision. Be advised, however, that this will require an additional 288 roof beam tables. We will post a notification when this project is complete and make these new tables available to users of the Guide.
If you have specific issues to discuss, please utilize the email button on the left and let us know.

Chapter 2 Page 6, Detail F2 referred to Table 205 for reinforcing requirements. Table 205 did not give reinforcing requirements. This later version of Page 55 corrects. Additionally, new calculations on the uplift capacity of various continuous edge footings (per Details F1 & F2) show increased capacity over the previous values in Table 205. The download page updates Table 205 accordingly.

Chapter 3, Screened Walls and Balconies. Page 3-4 shows an incorrect reference on the kickplate rail to a table which has been omitted in the 2007 edition (Table 303). The note should refer the user to Table 301 or 304 for the selection of the appropriate member for the kickplate rail, as is shown on the attached download. The download page corrects this problem.

Chapter 1, Screen Enclosures. Page 78 shows the allowable purlin spans for flat (horizontal) purlins when governed by the 300# live load requirement only. The AAF 2007 Guide has a limitation of 8' 0" for beam spacing and therefore purlin spans. With the exception of the 2X2 X 0.045", typical legacy hollow and SMB extrusions of 6005T5 and 6061T6 have an allowable span meeting the 300# concentrated load requirement for a span of 8' 0" (or greater).This page was not included in the Addendum 1.1 update. The download page corrects this problem.

Addendum 1.1 of the 2007 AAF Guide contains span tables for the enhanced strength alloys 6005T5 and/or 6061T6. The increased span capabilities of these alloys require a matching enhancement in the moment carrying capacity of the beam splices (mitered or straight). This download is a replacement page for 1-32. It has splice plate thicknesses and fastener requirements for the various potential combinations of gusset plate alloys and beam alloys.

2007 Edition Addendum 1.2 (date of posting June 10, 2009)
Addendum 1.2 is published and is now available for a $10 shipping and handling fee. [NOTE: this addendum is available only to those on record with the AAF state office as owners of the 2007 edition.]
THIS CD CONTAINS:
- All previously published errata.
- Design Flowcharts and Checklist (design aids).
- Update 1.1 - the tables in this update were approved by the Florida Building Commission as a part of the 2009 Amendments to the 2007 Florida Building Code. The tables are for the use of alloys 6005T5 and/or 6061T6 (higher strengths) as applied (only) to Chapter 1 (Pool Enclosures) using 20/20 screen mesh.
- Addendum 1.2 - These supplemental tables (there are about 300 tables) include:
- Longer spans for the substitution of 18/14 screen mesh instead of 20/20 mesh (allowed by a recent code provision in Table 2002.4)
- Member spans in Chapters 2 & 3 for the higher strength alloys and both screen densities.
USER NOTE FOR ADDENDUM 1.2: This update has not yet been approved by the Florida Building Commission, building departments may or may not approve the use of any of these new tables at their discretion. While the AAF stands behind the design information included in Addendum 1.2, we cannot guarantee its acceptance by any building authority.

2007 Edition Technical Bulletin #1.1, May 5, 2009
The Florida Building Commission considered code amendments during a code revision cycle known as the "glitch" cycle (during 2008). The product of these considerations and decisions was a set of provisions known as the 2009 update (or amendments) to the 2007 Florida Building Code.
In that code revision cycle, a set of updates and revisions to the 2007 edition of the AAF Guide were offered and approved by the commission.
Those which are now incorporated into the Guide are listed on the Acrobat (pdf) document.

PLEASE NOTE: the AAF Guide is sold on compact disk and is copy-protected. The changes listed as 2009 amendments are not on this CD. You must request an additional CD by contacting the AAF state office.
2007 Edition Technical Bulletin #1.0, March 17, 2007
Question: Can I use a 3X3 post in a screen room, and, if so, what tables do I use for the allowable spans?
Answer: Yes, you can use 3X3's in a screen room. The allowable spans for a 3" X 3" X 0.090" post in a screen room is equivalent to a 2X6 SMB, and for the 3"X3"X0.125" square tube, use the 2X7 SMB tables. Use the tables in Chapter 2 appropriate for the wind zone and exposure category for the project under consideration.
Errata for the 2007 Edition Guide to Aluminum Construction in High Wind Areas (2007 Version 1.0)
The following Errata/Updates have been released. Please download these documents, these pages replace their respective counterparts.
August 26, 2008 ~ Errata Pages for the 2007 Version 1.0 Edition (released on CD)
(Please note that these errata do not differ in any technical respects, these are cosmetic errata only)
Screen Visibility Problem: If less than the entire page is visible on your screen when viewing the guide from your CD, it is most likely a screen resolution problem on your computer. Inspect your screen resolution properties (right-click your mouse in the center of the screen on a blank desktop) and try changing to a higher screen resolution (Settings tab).
Other Notes:
To Whom It May Concern:
Please be advised that the assumed soil pressure for foundation designs shown in the AAF Guide to Aluminum Construction in High Wind Areas is 2,000 psf.
