What is AAMA 502?

The AAMA 502 (Voluntary Specification for Field Testing of Newly Installed Fenestration Products) is a field-testing guide developed by the American Architectural Manufacturers Association (AAMA). This guide illustrates test procedures to ensure air and moisture penetration is minimized in new window installations.

How long is a water test on Windows?

15 minutes
Water infiltration testing is typically performed according to ASTM E 1105. This test consists of placing the window unit under a specified static air pressure, and then wetting the window exterior in a controlled manner with a spray rack for a duration of 15 minutes.

What is AAMA 511?

The AAMA 511 (Voluntary Guideline for Forensic Water Penetration Testing of Fenestration Products) is a guide developed by the American Architectural Manufacturers Association (AAMA).

What is ASTM E1105?

ASTM E1105, Procedure A – Water penetration testing is conducted at the specified air pressure differential while simultaneously spraying water on to the exterior face of the assembly at the required rate of 5 gph/ft2. During testing, the interior face of the test area is inspected for water leakage.

What is ASTM E330?

ASTM E330/E330M-14 – Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference.

How do you check for air leaks on windows?

If you are still having a hard time finding the air leak, try a candle test. Light a candle and trace the sides of your window from inside your home. If you notice the flame or smoke pulling, then that’s where your leak is.

What is ASTM for windows?

The ASTM E 1105 (Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Wall by Uniform or Cyclic Static Air Pressure) is the “go to” standard when field testing newly installed fenestration products.

What is ASTM e779?

Standard Test Method for Determining Air Leakage Rate by Fan Pressurization. 1.1 This test method measures air-leakage rates through a building envelope under controlled pressurization and de-pressurization.

What is ASTM E547?

The ASTM E547 (Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Cyclic Static Air Pressure Difference) is a testing standard of procedures used to determine the water penetration resistance of windows, curtain walls, skylights, and doors when water is applied using …

What causes water leaks around windows?

Water is coming in around the window. Often, these leaks happen because the caulk or sealant around the window has gotten old and cracked, allowing rain to enter the house. The fix for this situation is simple – peel out the old caulking and replace it with new window caulking.

What is a good air leakage rating for windows?

0.3
A good air leakage rating is one below 0.3. Ratings below 0.3 are recognized as energy efficient by both the NFRC and ENERGY STAR. Windows with ratings closer to 0.1 are the most efficient.

What is the best way to seal drafty windows?

2. Caulk the gap.
3. Refresh glazing putty.
4. Add in weatherstripping.
5. Seal drafty windows with nail polish.

What ASTM 2112?

ASTM E 2112 prescribes the instal- lation of windows, patio-type doors and skylights as used primarily in residential and light construction commercial buildings. Adopting ASTM E 2112 allows designers to rely solely on windows to resist water penetration, independent of the adjoining wall assembly.

How do you test for air tightness?

To complete an air tightness test, access to an empty dwelling is required. Air testers install blower door testing equipment – essentially big fans – to an external opening like a doorway. They will then use this to pressurise the building and test over pressure differences.

What is an envelope leakage test?

An envelope leakage test is performed with a blower door. The blower door consists of a powerful, calibrated fan, installed in an exterior doorway which creates a pressure difference between the inside and outside of the building, thereby forcing air through the breaches and penetrations of the building envelope.

Where do windows typically leak?

Leaks at the top or bottom of the window are often a result of leakage in the structure. If the window leak is visible in the area where the window sash meets the jamb, or on the window frame, chances are the problem is in the window itself.

Does Flex seal work on windows?
