Quaker’s Historical Windows recognized as part of Metamorphosis Award Winning Projects


Quaker’s windows and doors are independently tested to maintain
performance and durability and are also tested in-house, in accredited
Quaker test labs, to make sure they are performing up to our high
expectations. Products are tested for design performance, thermal
performance, energy performance, and water performance. For coastal
areas, Quaker has a variety of fully tested, impact-rated products to
withstand the most volatile weather. The AAMA test ratings for Quaker’s
aluminum products are AW certified, with a range from CW-40 to AW-80,
and Quaker’s product design yields high design pressure ratings ranging
from 35-50. Not only are the products life cycle tested to meet stringent
industry standards, but they are also tested to standard gateway size as
well as the designed maximum size and weight.
