Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
The ProSill™ installation method for SAINTY bi-fold doors requires precise rough opening measurements and a perfectly level sill substrate to ensure smooth folding operation. Installers must prioritize the placement of shims at both the jambs and the head track to maintain a square frame, preventing binding of the heavy-duty rollers over time.
Critical waterproofing involves the application of AAMA-compliant sill flashing and continuous beads of high-performance sealant at all frame joints. We recommend a multi-point lock calibration after the final glazing installation to account for structural settling and to ensure the EPDM gaskets achieve a full airtight seal against the frame.

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 wind load and structural ratings do these bi-fold doors achieve?
SAINTY Hurricane-Rated Bi-Fold Doors are tested to achieve a Design Pressure (DP) rating of up to DP70 in accordance with ASTM E330 standards. This high-strength performance is achieved through 6063-T5 aluminum profiles and reinforced stainless steel multi-point locking systems, making them suitable for coastal regions where high-velocity wind loads and debris impact protection are critical requirements.
Are these doors compliant with US energy codes and NFRC standards?
Yes, our bi-fold doors are rated per NFRC 100-2020 and achieve U-Factors between 0.20 and 0.32 Btu/h·ft²·°F. By utilizing a 24mm to 34mm PA66 GF25 polyamide thermal break and double-pane insulated glass with Low-E coatings, these units maintain a SHGC of 0.23 or lower, ensuring compliance with most residential energy codes across the United States.
How is water penetration prevented in heavy storm conditions?
SAINTY bi-fold systems are engineered to resist water penetration at a minimum test pressure of 720 Pa (15 psf). The design incorporates multi-layered EPDM gaskets and a specialized sill drainage system that channels water away from the interior, preventing leaks even during the sustained wind-driven rain typical of North American hurricane seasons.
Do SAINTY hurricane-rated aluminum bi-fold doors comply with United States energy code requirements?
Yes. SAINTY Hurricane-Rated Aluminum Bi-Fold Door units are fully compliant with United States energy code requirements, achieving a certified U-Factor of 0.20 – 0.32 Btu/h·ft²·°F (NFRC 100) and an SHGC of ≤ 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.
