B. Performance Requirements
1. Structural Members: Of sufficient sizes to support design loads as prescribed by governing building codes.
2. The deflection of the framing member in a direction normal to the plane of glass when subjected to uniform load deflection
test in accordance with ASTM E330, and per the above- specified loads, shall not exceed L 1/175.
3. The deflection of a framing member in a direction parallel to the plane of glass, when carrying its full dead lad, shall not
exceed an amount which will reduce the glass or panel bite below 75% of the design dimension and the member shall
have a 1/8" minimum clearance between itself and the edge of the fixed panel, glass or component immediately adjacent,
nor shall it impair the function of or damage any joint seals.

accordance with ASTM E331 using a differential static pressure of 20% of the inward
acting design wind load pressure, but not less than 12psf. Water penetration is defined
as the appearance of uncontrolled water other than condensation on the interior surface of
any part of the sun room.
a. Drain water penetrating at joints, as well as condensation occurring within the
