Education of AAMA Document 812-04
AAMA recently issued Document 812-04 to address single component aerosol expanding polyurethane foams, after widespread recognition that these products can greatly enhance the installation quality of prime and replacement fenestration products by sealing the rough opening to provide a highly effective air barrier.
Proper Window Installation
In addressing the importance of insulating the shim space of a window, one can see that Handi-Seal®, an expanding, low pressure build, closed-cell, polyurethane foam has marked advantages to that of chinking fiberglass. A product such as one-component polyurethane foam can serve as the extra insurance policy against moisture infiltration due to improperly installed windows.
The Industry Acceptance of Foam as a Fireblock Material
Many of the traditionally specified fireblocking prescriptive approaches are tedious, time-consuming and difficult to apply. Using Hand-Foam® Fireblock instead of these prescriptive methods provides significant savings in labor costs, in addition to providing a more efficient and effective seal which also insulates and prevents air infiltration.
Clarifying the Difference Between Fireblock and Firestop1
Until recently, most of the United States used the term "firestopping" interchangeably with "fireblocking" or "draftstopping" when describing two different construction objectives. However, it is important to understand the significant difference between a "Fireblock" and a "Firestop".
