UFC Unified Facilities Criteria 1. UFC DoD Minimum Antiterrorism Standards for Buildings G. VA Department of Veterans Affairs 1. Architectural Design Manual, May SYSTEM DESCRIPTION A. AAMA Designation: DAW-AW50. B. Windows: 3-1/4" frame depth; extruded aluminum with integral structural thermal break made with glass-reinforced nylon strips installed by the window manufacturer in the frame and vent members; equal-leg frame; exterior and interior finishes applied by the window manufacturer; frames and vents assembled by the window manufacturer. C. Configuration: turn-only window; overlap vent; single vent per frame. D. Glazing: exterior aluminum glazing bead; exterior open-cell foam encased in black thermoplastic elastomer (TPE) for UV stability; laminated, insulating glass; interior 2-part structural silicone; glass description in paragraph 2.3; glazed by the window manufacturer. 1.5 PERFORMANCE REQUIREMENTS A. Conformance to DAW-AW50 specifications in AAMA/WDMA/CSA 101/I.S.2/A when tests are performed on a 60 x 99 minimum frame size with the following test results: B. Air Infiltration: after the AAMA life cycle test, meet AAMA 101 standard of maximum.1 cfm/square foot when tested per ASTM E at a static air pressure difference of 6.24 psf. C. Water Penetration: after the AAMA life cycle test, no uncontrolled water leakage when tested per ASTM E and ASTM E at a static air pressure difference of 12 psf. D. Uniform Deflection: no more than L/175 when tested per ASTM E at a static air pressure difference of 50 psf. E. Uniform Structural: window to be operable, and maximum.2% permanent deformation per member when tested per ASTM E at a static air pressure difference of 75 psf. F. U-Value Simulation: thermal computer simulation per NFRC , at the prescribed 47" x 59" Non- Residential Size, glazed with 1 insulating glass made with exterior 1/8 soft coat low E glass, thermoplastic butyl spacer, argon gas, and interior 1/8 clear glass: Thermal Transmittance to be maximum 0.38 BTU/HR/SQ.FT/ F U value. 1.6 BLAST RESISTANCE A. All glazing shall be designed using WinGARD V3.15 or later software or HazL V1.2 to achieve a glass performance condition 3b (i.e., glazing fails but fragments land on floor no further than 3 m (10 ft.) from the vertical plane of the window). 1. The analysis shall account for the height of the bottom of the glazing to the floor in determining the performance condition. 2. The glazing shall be designed for a GP2 blast load. 3. All glazing shall consist of laminated glass for single pane constructions or laminated glass for the inboard (non-threat side) pane of an insulating glass unit (IGU) constructions. B. All glazing shall be adhered to its supporting frame using structural silicone sealant or adhesive glazing tape. 1. The width of the structural silicone sealant bead shall be at least equal to the larger of 10-mm (3 8- in.) or the thickness designation of the glass to which it adheres, but not larger than two times the thickness designation of the glass to which it adheres

3 2. The minimum thickness of the structural silicone bead shall be 5-mm (3 16- in.). 3. The width of glazing tape shall be at least equal to two times but not more than four times the thickness designation of the glass to which it adheres. 4. The structural silicone bead or glazing tape shall be applied to both sides of single pane laminated glass constructions, but need only be applied to the inboard side (non-threat side) of IGU constructions. C. The frames and mullions for all blast resistant glazing shall transfer the dynamic reaction loads from the glazing into the supporting structure as follows. 1. Connections of frames directly to the structure (i.e. steel tubes) shall have a nominal design capacity that resists an equivalent static load equal to the reaction loads from the peak resistance of the window (Rmax), as determined from WinGARD or HazL, uniformly distributed around the perimeter of the glazing. 2. Mullions shall be designed to resist either the calculated dynamic reactions from the glazing response or the design blast load over the tributary area using dynamic analysis, with a maximum deflection of L/30 where L is the mullion span length. The connections of mullions shall be designed to resist reaction forces based on the ultimate flexural resistance of the mullion or the peak dynamic reaction force determined in the dynamic analysis. 1.7 SUBMITTALS A.
