Third-Party Assurance of Quality

Alside is committed to engineering and manufacturing the highest quality windows, and researching and developing the innovations that will continue to place Alside at the top of the industry.

Alside partners with objective, third-party organizations that continuously test our products and verify that we meet the highest standards of performance, quality, value and safety.

The American Architectural Manufacturers Association ​(AAMA) is internationally recognized for the development of stringent performance standards. Every window and door that boasts AAMA certification undergoes extensive independent testing for resistance to water leakage, air pressure and impact.

The American Society for Testing and Materials (ASTM) is a non-profit organization that provides a forum for the development and publication of voluntary consensus standards for materials, products, systems and services. ASTM standards serve as a basis for manufacturing, procurement and regulatory activities.

The National Fenestration Rating Council (NFRC) establishes test criteria that set the standard for performance ratings for manufacturers of window and door products. The primary goal of the NFRC is to provide accurate information on the energy performance of these products.

The Insulating Glass Certification Council (IGCC) is a non-profit organization jointly established in 1977 by manufacturers, consumers, specifiers and others concerned with the quality and performance of insulating glass units. IGCC sponsors and directs an independent, true third-party certification program. Periodic accelerated laboratory tests, per American Society for Testing and Materials (ASTM) specifications, and unannounced plant quality audits and inspections assure the quality and performance of sealed insulating glass products.

ENERGY STAR® program is a joint venture between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (U.S. DOE) designed to encourage homeowners to purchase energy-efficient products. Using less energy in our homes reduces the amount of CO2 emissions released into the atmosphere from burning fossil fuels such as coal, oil and natural gas.


Pre-Finished Interior Trim


UltraTrim™ is produced with perfection in mind. By utilizing the same high-grade vinyl laminate used in the manufacture of your Alside Windows, we can painstakingly match the wood tone and grain of our window products. Our solid-color trim is also guaranteed to be an exact match to your Alside solid-color windows, so you don’t have to worry about painting.

Alside not only offers five popular molding profiles to coordinate with most any décor you have in mind, but our moldings are ideal for all our standard window styles as well as bay, bow and garden windows.

With subtle sophistication, UltraTrim interior finishes convey a warm and welcoming ambiance while beautifully reflecting your personal taste. Interior selections include White and Beige, as well as laminate wood grains in Rich Maple, Light Oak, Dark Oak, Foxwood and Cherry.
