Understanding Window Performance Ratings

You don't need to spend more to buy a good window. This information is for engineers. I encourage you to continue reading even if you're not an engineer. This explanation will explain the meaning of performance ratings. A poor decision is almost guaranteed if you don't do enough research. Only proper research can reveal the truth.

Windows that are energy efficient

We recommend looking at four ratings when evaluating replacement windows. The most energy-efficient products are highly efficient and have high energy performance ratings. We recommend that you take a look at the ratings and who certifies the product. This will help you understand why AAMA certification is so important.

U-Factor

The U-Value is a measure of heat flow through a window. This number will determine how well it blocks heat flow. Virginia Beach, Va requires a U Factor below.30. The Air Infiltration Rating section below addresses this issue.

SHGC, or Solar Heat Gain Coefficient

Solar Heat Gain Coefficient measures the transmission of solar heat. Higher SHGC values indicate that more solar heat is being transmitted through window glass. A higher SHGC value is preferred for colder climates, while a lower value is better for warmer ones. We recommend that you use a U factor between.20 to.30 in the Tidewater region of Virginia.

Design Pressure or DP Rating

Many variables can affect the DP rating of a window. We will not make it complicated by listing them all. The DP Test measures the product's strength against hurricane-force winds, water penetration, and other severe weather conditions. A DP rating of 50 is preferred, although in some cases, a DP score of 35 will work as long as the window has been AAMA Gold Label Certified. If the window does not have the AAMA Gold Label Certified, it is best not to consider it.

AIR

Air loss is common around doors and window frames. It makes sense, therefore, that windows should be as airtight as possible. This rating is critical. This is a critical rating. No matter how solid or efficient the window's frame or glass, air leakage can cause damage. Air leakage numbers will drop the more tightly a window is sealed. For energy-saving windows, a. ten air rating or lower should be your goal.

AAMA Gold Label

Commercial windows manufactured by window companies in Virginia beach must be certified to meet the building code. A lot of residential windows aren't AAMA-certified, even though they should. AAMA gold label certified windows can guarantee that they have passed all necessary tests and that the window will be safe and sound. The AAMA will also send independent inspectors twice a year to inspect each manufacturer to verify that the window installed in your home is identical to the one tested. It would help if you always verified the gold label before you assume anything, regardless of how Anderson Windows (AKA Anderson Windows), Marvin Windows, or vinyl replacement windows.

Manufacturers will go to great lengths for their window products to be tested by an AAMA approved facility and certified Gold Label by the AAMA. Double-check your product, as many manufacturers and salespeople will attempt to mislead. The AAMA Gold Label will be found in the frame cavity for any AAMA Gold Label-certified window.

For the average Window World product, with an exterior wrap and Energy-efficient glass, custom windows start which is affordable. Window replacement costs and window prices will be higher for windows with lower Air Infiltration ratings.
