Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
Installation of the SAINTY™ Bi-Fold Door requires precise leveling of the head track and sill to ensure smooth panel glide. We recommend following ProSill™ flashing standards to provide a continuous water barrier. The bottom-rolling system must be set on a perfectly flat substrate; use load-bearing shims at all hinge points and jamb fixings to prevent frame deflection.
Final calibration of the multi-point lock and handle interface should be performed after the EPDM gaskets have fully seated. Ensure that the weep holes in the sill remain unobstructed during the perimeter sealing process to maintain the 720 Pa water penetration rating.

Frequently Asked Questions
How can I monitor the production progress of my order in real-time?
Once your CAD drawings are approved, you can log into the SAINTY platform to follow our 11-step manufacturing pipeline, view live site photos, and track shipping status — from material preparation and factory production through loading inspection, ocean freight, customs clearance and jobsite delivery.
What does SAINTY's 11-step order tracking process include?
The pipeline covers: CAD drawing approval, material preparation, profile machining, factory production, glazing & hardware installation, quality inspection, protective packing, loading inspection, ocean freight, customs & delivery, and jobsite delivery. 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 does this bi-fold door achieve for US building codes?
This system achieves a U-Factor of 0.28 Btu/h·ft²·°F and an SHGC of 0.22, as rated per NFRC 100-2020. These metrics ensure compliance with the most stringent energy efficiency requirements in the United States, utilizing double-pane 5mm+12A+5mm Low-E insulated glass units to minimize thermal transfer and reduce HVAC loads.
How does the door perform against high winds and water penetration?
The SAINTY™ Bi-Fold Door is tested to AAMA/WDMA/CSA 101/I.S.2/A440 standards, achieving a Design Pressure rating of DP50 and water penetration resistance of 720 Pa (15 psf). The heavy-duty 6063-T5 aluminum frames and multi-point locking hardware ensure the system remains air-tight and structurally sound during severe weather events.
What type of maintenance is required for the track and hardware system?
Maintenance is minimal due to the use of SS304 stainless steel grade hardware and a precision-engineered bottom-rolling track. We recommend a semi-annual inspection of the EPDM gaskets and cleaning the bottom track of debris to ensure the smooth operation of the multi-panel folding mechanism and to maintain the 5-year hardware warranty coverage.
Do SAINTY energy efficient aluminum bi-fold doors comply with United States energy code requirements?
Yes. SAINTY Energy Efficient Aluminum Bi-Fold Door units are fully compliant with United States energy code requirements, achieving a certified U-Factor of 0.30 and an SHGC of SHGC 0.22 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.
