Installation Manual — SAINTY™ Soundproof Aluminum Bi-Fold Doors
SAINTY Soundproof Aluminum Bi-Fold Doors require precise technical adherence to maintain their certified acoustic and thermal ratings. These systems must be installed according to AAMA Standard Sill Flashing practices to ensure Water Penetration Prevention tested to 720 Pa. Installation workflow involves Rough Opening Measurements, Header Load Bearing Verification, Shim Placement at hinge and pivot points, and EPDM Gasket Sealing at all frame joins.

Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
For successful ProSill™ installation of SAINTY bi-fold doors, ensure the structural header is engineered to support the specific weight of the triple-pane panels. The rough opening must be square and level within 1/8 inch to prevent track binding. Use high-performance EPDM flashing at the sill and jambs to maintain the system's soundproof integrity.
Proper shim placement at each hinge point and lock strike is critical for long-term alignment. We recommend applying a continuous bead of structural sealant under the sill pan per AAMA flashing standards to prevent water infiltration at the 720 Pa threshold.

What is the certified sound insulation performance of these bi-fold doors?
SAINTY bi-fold doors are tested to achieve an STC acoustic rating between 32 and 42 depending on the specific glazing configuration. By utilizing triple-pane insulated glass and a 34mm PA66 GF25 thermal break, the system effectively mitigates high-frequency noise, making it an ideal choice for high-end villa projects requiring soundproof certification.
Are these bi-fold doors compliant with U.S. energy and structural codes?
Yes, the system is rated per NFRC 100-2020 and tested to AAMA/WDMA/CSA 101/I.S.2/A440 standards. Our configurations for the United States market achieve a U-Factor as low as 0.28 Btu/h·ft²·°F and a design pressure rating of DP50, ensuring compliance with most regional building codes including coastal requirements.
What type of hardware and security features are included?
SAINTY utilizes Grade 304 stainless steel multi-point locking hardware to ensure both longevity and security. The hardware is tested for cycle durability and features heavy-duty rollers and top-hung or bottom-rolling tracks that maintain smooth operation even with heavy triple-pane glass loads.
Do SAINTY soundproof aluminum bi-fold doors comply with United States energy code requirements?
Yes. SAINTY Soundproof Aluminum Bi-Fold Doors units are fully compliant with United States 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.
