Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
Successful installation of SAINTY Bi-Fold Doors requires precise rough opening measurements and a perfectly level structural header to support the heavy-duty track system. We recommend the ProSill™ integrated sill flashing method to ensure watertight integrity at the threshold, especially in slab-on-grade Texas villa constructions.
Installers must focus on shim placement at each hinge point and the primary locking jamb to prevent frame deflection. EPDM gasket sealing must be continuous at all panel intersections to meet the tested air infiltration rating of 0.06 cfm/ft².

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.
Are these bi-fold doors rated for high wind loads in Texas?
Yes, SAINTY Bi-Fold Doors are tested to ASTM E330 standards, achieving a Design Pressure rating of DP50 to DP70. This structural performance is critical for Texas coastal and inland regions prone to high wind pressure, ensuring the 6063-T5 aluminum frames and multi-point locking systems remain secure under extreme environmental stress.
What thermal performance can be expected with the triple-pane glazing?
SAINTY Bi-Fold Doors achieve a U-Factor as low as 0.28 Btu/h·ft²·°F when configured with our triple-pane insulated glass units (5mm+12A+5mm+12A+5mm). This configuration, rated per NFRC 100-2020, significantly reduces heat gain in the Texas climate while maintaining a Visible Transmittance (VT) between 0.40 and 0.55 for optimal natural lighting.
What type of threshold and hardware is used for large villa openings?
We utilize heavy-duty 304 stainless steel bottom-rolling hardware and specialized drainage thresholds to support the weight of wide-span panels. The hardware is tested to AAMA standards for cycle life, ensuring the multi-panel system operates smoothly without sagging, even at maximum opening widths typical of luxury villa designs.
Do SAINTY aluminum bi-fold doors comply with Texas energy code requirements?
Yes. SAINTY Aluminum Bi-Fold Doors units are fully compliant with Texas energy code requirements, achieving a certified U-Factor of 0.26 - 0.32 Btu/h·ft²·°F 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.
How do SAINTY thermal break aluminum bi-fold doors compare to standard non-thermal aluminium windows in Texas?
Unlike non-thermal aluminium frames, which typically show U-factors above 0.50 Btu/h·ft²·°F, SAINTY uses a 24mm - 34mm PA66 GF25 Polyamide thermal break and Low-E insulated glazing to reach a certified U-Factor of 0.26 - 0.32 Btu/h·ft²·°F. That reduces conductive heat transfer and HVAC loads substantially while meeting NFRC 100-2020 and, where applicable, California Title 24 Part 6 requirements.
