Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
ProSill™ installation for bi-fold systems requires precise leveling of the recessed sub-sill to ensure smooth track operation. Installers must ensure the rough opening is square within 1/8 inch and utilize high-density shims at every hinge pivot point to support the weight of the active leaves.
For Florida villa applications, ensure the perimeter is sealed using a three-stage waterproofing method, including EPDM gasket integration and high-performance silicone sealant, to maintain the 720 Pa water penetration resistance 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.
Do these bi-fold doors meet Florida Product Approval requirements?
Yes, our impact-resistant bi-fold doors are tested to AAMA/WDMA/CSA 101/I.S.2/A440 standards and carry specific Florida Product Approval documentation for high-velocity hurricane zones. These units are rated for a design pressure of DP70 (ASTM E330) and feature laminated impact glass capable of withstanding large missile impacts typical of tropical storm conditions.
What is the thermal performance rating for this bi-fold system?
The SAINTY bi-fold system achieves a U-Factor of 0.28 Btu/h·ft²·°F when rated per NFRC 100-2020. By utilizing double-pane insulated glass with a low-E coating and argon fill, the system maintains a Solar Heat Gain Coefficient (SHGC) of 0.22, effectively reducing cooling loads for Florida residential applications while providing clear visible transmittance.
What hardware is used to prevent corrosion in coastal Florida environments?
We exclusively use SS304 or SS316 stainless steel for all hinges, rollers, and multi-point locking mechanisms to prevent salt-air corrosion. The frames are finished with AAMA 2605 compliant powder coating, which is the highest industry standard for color retention and chemical resistance in high-exposure coastal sites.
Do SAINTY impact resistant aluminum bi-fold doors comply with Florida energy code requirements?
Yes. SAINTY Impact Resistant Aluminum Bi-Fold Door units are fully compliant with Florida energy code requirements, achieving a certified U-Factor of 0.28 Btu/h·ft²·°F and an SHGC of 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.
