Installation Support
DIY-friendly: owners and contractors get 1-on-1 factory technical support.
Successful installation of the SAINTY™ Bi-Fold Door in cold climates requires strict adherence to the ProSill™ flashing system to prevent thermal bridging at the threshold. Installers must ensure the rough opening is perfectly level, as the heavy triple-pane panels require precise track alignment for smooth operation. Use high-performance low-expansion foam and EPDM perimeter gaskets to maintain the 0.22 U-Factor rating.
We recommend shimming at every hinge point and locking station. Because of the thermal expansion differences between the aluminum frame and the building structure in Colorado, a minimum 3/8-inch expansion gap is required, filled with architectural-grade sealant compliant with AAMA 800 standards.

Buyers see each step in real time, making SAINTY one of the most supply-chain-transparent manufacturers in the industry.
What U-Factor performance can I expect for Colorado's cold climate requirements?
Our triple-pane Bi-Fold Doors achieve a U-Factor of 0.22 Btu/h·ft²·°F when tested to NFRC 100-2020 standards. This performance level is achieved through a 34mm PA66 GF25 polyamide thermal break and argon-filled 5mm+12A+5mm+12A+5mm glazing, ensuring compliance with strict regional energy codes for thermal retention.
How does this door handle high wind loads and air infiltration at high altitudes?
The system is tested to AAMA/WDMA/CSA 101/I.S.2/A440 and achieves a design pressure rating of DP50. It maintains an air infiltration rate of no higher than 0.06 cfm/ft² at 1.57 psf per ASTM E283, utilizing multi-layered EPDM weatherstripping to prevent drafts and heat loss in exposed mountain environments.
Are these doors compliant with local Colorado building codes for water resistance?
Yes, our Bi-Fold Doors are engineered to a water penetration resistance class of 720 Pa (15 psf) minimum test pressure. This rating ensures that even during driving sleet or heavy rain, the internal drainage channels and ProSill™ compatible thresholds prevent moisture ingress as per ASTM E331 requirements.
Do SAINTY thermally broken aluminum bi-fold doors comply with Colorado energy code requirements?
Yes. SAINTY Thermally Broken Aluminum Bi-Fold Door units are fully compliant with Colorado energy code requirements, achieving a certified U-Factor of 0.22 Btu/h·ft²·°F and an SHGC of 0.21 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.
