Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
ProSill™ installation for SAINTY sliding windows requires precise leveling of the sill track to ensure fluid movement of the rollers and effective drainage through the weep holes. If panels exhibit wobble or uneven movement, check the top guide rollers and ensure the frame is square within 1/8 inch across the diagonals.
Apply high-performance sealant at all frame corners and mechanical joints. Shim placement should be concentrated at the jambs and sill to support the weight of the double-glazed units without bowing the extrusions, ensuring the multi-point lock aligns perfectly with the keepers.

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 specifications do these sliding windows meet?
SAINTY sliding windows are tested and rated per NFRC 100-2020 to achieve U-Factors between 0.20 and 0.32. By utilizing insulated glass units with argon filling and Low-E coatings, these windows maintain an SHGC of 0.23 or lower, ensuring compliance with strict energy codes while providing a Visible Transmittance (VT) between 0.40 and 0.65.
How is the structural integrity and weather resistance verified for North American climates?
All units are tested to AAMA/WDMA/CSA 101/I.S.2/A440 standards, achieving water penetration resistance at a minimum of 720 Pa (15 psf). The structural design is rated between DP30 and DP70 per ASTM E330, utilizing SS304 multi-point locks and reinforced frame joinery to withstand high wind loads and heavy precipitation.
Do SAINTY thermally broken aluminum sliding windows comply with US energy code requirements?
Yes. SAINTY Thermally Broken Aluminum Sliding Windows units are fully compliant with US energy code requirements, achieving a certified U-Factor of 0.20 - 0.32 Btu/h·ft²·°F 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.
How do SAINTY thermal break thermally broken aluminum sliding windows compare to standard non-thermal aluminium windows?
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 0.20 - 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.
