Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
For optimal performance of SAINTY folding windows, the sill must be perfectly level and the rough opening square within 1/8 inch. During the installation of folding panels, the screw sequence on the SS304 hinges is critical: align the hinge and tighten the center screw first while leaving the others loose. Repeat this sequence for the top, middle, and bottom hinges to ensure proper panel weighting before securing all remaining fasteners.
Ensure that the PA66 GF25 thermal break is not bypassed by fasteners and that all perimeter gaps are filled with high-quality low-expansion foam and sealed with AAMA-compliant flashing to prevent water intrusion at the rough opening interface.

Every milestone is documented with photos in the SAINTY app.
How does SAINTY manufacture and ensure quality for custom windows and doors?
Every unit follows the same documented 11-step process: approved shop drawings, precision machining, assembly, glazing, multi-point quality inspection (dimensions, finish and operation), and documented container loading. Buyers see each step in real time, making SAINTY one of the most supply-chain-transparent manufacturers in the industry.
What thermal performance ratings do these folding windows achieve for US climates?
SAINTY folding windows achieve a U-Factor between 0.20 and 0.32 Btu/h·ft²·°F as rated per NFRC 100-2020. Utilizing triple-pane insulated glass with a 5+12A+5+12A+5 build-up and argon gas fills, these units effectively minimize heat transfer, making them suitable for energy-efficient homes across diverse American climate zones.
How do these windows perform against high wind and water infiltration?
These units are tested to AAMA/WDMA/CSA 101/I.S.2/A440 and achieve a design pressure rating of up to DP70. Water penetration resistance is verified at a 720 Pa (15 psf) minimum test pressure, utilizing EPDM gasket sealing and multi-point locking hardware to ensure airtight and watertight performance during extreme weather events.
Are the finishes suitable for coastal or high-exposure residential areas?
Yes, our frames are coated to AAMA 2604 as a standard, with AAMA 2605 available for maximum salt spray and UV resistance. The powder coating process ensures long-term color retention and corrosion resistance, backed by a 10-year structural warranty for residential applications in the United States.
Do SAINTY powder coated aluminum folding windows comply with United States energy code requirements?
Yes. SAINTY Powder Coated Aluminum Folding Windows units are fully compliant with United States energy code requirements, achieving a certified U-Factor of 0.30 and an SHGC of SHGC ≤ 0.23 when tested under NFRC 100-2020 and NFRC 200-2020 procedures. Performance is verified on AAMA/WDMA/CSA 101/I.S.2/A440 tested assemblies, and the NFRC label certificate is supplied with every order for permit submission.
