How is FoldUp™


Highly skilled craftsmen utilizing state-of-the-art design and manufacturing equipment along with traditional hand construction methods assure that each FoldUp™ window is built to the very highest standards.  All components of the window (except some locking hardware options) are made 100% in the US.


Was Testing done on

FoldUpTM Windows?

Various tests have been performed on FoldUp™ windows, including tests on many of the individual materials, components, and fasteners to ensure safe and reliable performance.  Standardized tests have also been performed including those for Air, Water, and Structural (AAMA/WDMA/CSA 101/I.S.2/A440-08) and Thermal Performance (NFRC). Most FoldUp™ windows will comply with California’s new Title 24 energy code. Test results are available to design professionals at our Professional Login page, or by contacting a FoldUp™ representative or dealer.
