... (RH) of 48 % RH at 21°C (70°F). Due to a lack of containment of the moist interior air, condensation formed in the exterior walls, in the roofing, on the window and door systems, and on the skylights of the facility, particularly along the north and east elevations of the building, which resulted...

... Collaborative efforts over several years resulted in the development of ASTM E2112, “Standard Practice for the Installation of Exterior Windows, Doors and Skylights”. Individuals from the window, sealant, and air barrier industries were involved in the development of the standard. Development...

... Current standards for installation of fenestration units, such as ASTM E2112-07, “Standard Practice for Installation of Exterior Windows, Doors and Skylights” do not address regional considerations, or how the level of wind and rain exposure could influence installation methodology...

... Self-adhered flashing products can very effectively maintain a durable moisture-tight seal at the window-wall interface, which is highly vulnerable to moisture intrusion. However, it is essential that these products be installed under conditions where adequate adhesion to the substrate...

...-driven rain or specifically the occurrence and level of extreme rainfall events for locations of interest. A review of climate information on wind-driven rain is provided, and its relevance to assessing the watertightness performance of walls, windows, and wall-window interfaces is discussed. Values...

... In the last few years, using window flashings to keep moisture out of wall systems has become an increasingly used practice. Builders have identified moisture intrusion as a key reason for callbacks. Window flashing products are expected to keep moisture from entering a wall system, around...

... Thermal breakage caused by the uneven heating of glass by solar irradiance is one of the most common causes of annealed glass breakage in buildings. The classic thermal breakage situation occurs when the edges of a glass plate are shielded by the window frame system or significant building...

... The prevailing public sentiment is that glazing materials in a business or home are extremely vulnerable to penetration. One homebuilder recounted his personal feelings on the topic of residential security by saying, “if you want a fortress, don't put any windows in it.” A seemingly simple...

... a 15-year-old building that does not have any windows and buildings that are about five to ten years old that have windows, have revealed that failure of the joints between the EIFS and the windows and other openings in the EIFS, and at terminations in the EIFS, is the primary cause of water leakage...

... This paper presents an analysis of the results of field water infiltration tests of windows and sliding glass door assemblies that were conducted within the last five years. In all cases, the tests were conducted during the new construction process. The tests were performed using ASTM Standard...

... Critical to long-term performance of windows is the correct design, selection, and application of the sealant. Key aspects to correct sealant selection are a simultaneous combination of adhesion, movement capability, and durability. The movement capability is directly correlated to the glazing...

... In areas with high annual rainfall amounts, such as Florida, water leakage through operable windows and sliding glass doors is common, particularly at multistory applications. Although each leak is unique to the product and project, certain trends have developed. Investigations of water leakage...

... Most water leakage problems through windows and doors are the result of installation errors. Even the best system designs cannot overcome poor installation techniques. Simple mistakes such as the omission of an internal seal can result in major water leakage that damages building interiors...
