St. Thomas’s Island Microclimate Demands More

St. Thomas combines steep hillside terrain with aggressive coastal exposure. Constant trade winds carry salt-laden moisture across the island, attacking metal fasteners, exterior coatings, and glazing seals. Coupled with intense tropical heat and flash downpours, even minor exterior envelope flaws lead to rapid subterranean and high-elevation water intrusion.

JEC’s forensic expertise ensures your St. Thomas structure is designed and built to withstand the relentless degradation unique to island microclimates.

Wind and Water: Severe Caribbean Storm Considerations

St. Thomas faces extreme hurricane exposure. High-elevation hillside structures endure exaggerated wind speeds and wind-driven rain during tropical storms. On-site AAMA spray testing and ASTM air/water tightness testing are vital for certifying window, door, and curtain wall integrity against catastrophic storm forces.
