What is an aw window?

Architectural Window/AW: Typically larger institutional or high-rise / mid-rise buildings to meet increased loading requirements, and buildings where possible misuse of the fenestration products is expected.

What is a performance class?

A performance class defines a set of device capabilities that goes beyond Android’s baseline requirements. Each version of Android has its own corresponding performance class, which is defined in that version’s Android Compatibility Definition Document (CDD).

What is a performance grade?

Performance grade means that the product was tested at the applicable design pressure for all performance requirements identified by NAFS.

What is a good performance grade for Windows?

A window rated “R” 15 just passed for residential use only. An “R” 30 or 45 rated window will perform much better.

What is AAMA standard?

AAMA stands for American Architectural Manufacturers Association. An AAMA rating for fenestration is the standard for replacement windows and doors in Chicago by which companies products are accreted. The AAMA rating uses “Performance Grade” as a measurement rating.

What is structural test pressure for windows?

A higher DP value indicates a window or door that can withstand more wind, water, and/or structural load than a window with a lower DP. In practicality, a window or door with a structural DP rating of 50 has passed a structural test pressure of 75 pounds per square foot (equal to a 200 mph wind).

What is window performance class?

Window performance standards define window products by Performance Class (residential, light commercial, commercial, heavy commercial, and architectural) and Performance Grade (15, 20, 25, etc.). In general, R and LC class windows have smaller test sizes and are allowed less force to operate and lock.

What is a performance class A aircraft?

Flight performance class A Aircraft in this class must meet the highest requirements. For example, an engine failure in aircraft of this category must not automatically lead to an emergency landing. The aircraft must also be able to be operated safely on contaminated runways (snow, mud).

How is window performance grade calculated?

The Performance Grade is based on the design wind pressure, calculated from the building code, as noted previously. If the maximum design wind pressure is 25 pounds per square foot, then the Performance Grade needs to be 25 or greater.

How do you calculate PG grade of asphalt?

Performance Grade Specification The top several rows (all the rows above the “original binder” row) are used to designate the desired PG grade. For instance, if the average 7-day maximum pavement design temperature is greater than 52oC but less than 58oC then you should use the “< 58” column.

What is a good STC rating for windows?

STC is used to measure a window’s ability to reduce sound. The higher the rating, the better the sound control. The typical rating for single pane windows is 18-20 while a double glazed window is 28-32. Milgard Quiet Line windows can achieve an STC rating of up to 48, for exceptional sound control.

What is an AAMA rating?

Is there a maximum performance grade for AW?

This is higher than the caps specified in NAFS-05 for Classes R through HC– where the performance classes were capped at 2,880 Pa (60 psf) above the minimum gateway design pressure. There is no maximum Performance Grade for AW products.

Which is the least stringent Aw performance class?

“The Performance Class ratings should be regarded as an indication of the level of performance, with the least stringent requirements established for the R Performance Class and the most stringent for the AW Performance Class.

What are the 5 performance classes in Aama?

In the 1997 and 2002 editions, there were five performance classes, described as: “R” for Residential, “LC” for Light Commercial, “C” for Commercial, “HC” for Heavy Commercial and “AW” for Architectural. The descriptions were intended to act as a general guide in helping to determine which class was best suited for a particular application.

What are the differences between CW and Aw fenestration products?

AW products also require that permanent set not exceed 0.2 percent of the mullion span when tested to 150 percent of the design pressure while CW allows 0.3 percent and R and LC are less stringent at 0.4 percent.
