Aama Window Rating System

Aama 520 voluntary specification for rating the severe wind driven rain resistance of windows doors and unit skylights.

Aama window rating system.

2 97 voluntary specification for aluminum vinyl and wood windows and glass doors it establishes four performance requirements for a completed window or door. This joint effort between aama and the insulating glass manufacturers alliance igma is intended to explain in consumer language what each of the standards means in order for consumers to be able to discern if there are allowable characteristics within the glass in their windows doors or skylights. For reporting purposes the product type shall be typed in full or represented by abbreviations as shown in. These web pages provide a general overview of the standards specifications and test methods used in the window door and skylight industry relating to glass and glazing systems.

Each rating is split into two values. Door specific rating the circled value shows you the rating a door has received. I or temperature index is based on the csa a440 2 test method. There are three different condensation rating systems used in north america.

The performance based material neutral north american fenestration standard nafs governing windows doors and skylights aama wdma csa 101 i s 2 a440 is no exception. Solar heat gain coefficient measures how well a product can resist unwanted direct or indirect solar radiation. Door systems sliding doors and unit skylights for new construction and replacement applications. This radiation can cause your home to heat regardless of outside temperature which may be favorable or unfavorable depending on.

In order to be assigned this certification a window must meet the american architectural manufacturers association s standards for air leakage water penetration wind and forced entry resistance durability and thermal window performance. Cycle test including misuse. Fenestration standards are always evolving due to changes in technology building codes and rating system performance requirements. Note this is a laboratory test procedure for high velocity wind driven rain conditions with no correlation to wind zones and exposure categories.

The first aama voluntary standard for thermal performance was developed specifically to measure the condensation resistance of windows and sliding glass doors. Cr or condensation rating is based on the nfrc 500 testing and modeling methods. Aama started evaluating the thermal performance of windows and doors in 1972. Cycles of misuse and abuse.

Repeat air infiltration water penetration testing operating force. Since that time aama standards have evolved to include windows and doors of various materials and types as well as ensuring that emerging technologies are assessed. Products have to be independently tested in an official aama laboratory guaranteeing their reliable behavior in homes. Crf or condensation rating factor is based on the aama 1503 test method.

Voluntary standards for window manufacturers in 1997 the two groups joined forces to establish a unified standard for evaluating fenestration products known as aama nwwda 101 i s. The aama gold label is sort of like a shortcut to identify high performing quality products. Field testing of windows and doors. Solar heat gain and u factor.
