Buyer Guide
Choosing an Envelope System for a Coastal Project
How insulation, fasteners, coatings, joints and local climate affect roof and wall panel specifications.
Define the exposure conditions
Distance from the coastline, salt exposure, prevailing wind and rainfall all influence envelope specifications. These conditions should be discussed before panel thickness, coating and fastener selections are confirmed.
Review the complete envelope assembly
Roof and wall performance depends on more than the panel itself. Fasteners, sealants, flashings, laps and penetrations must work as a coordinated system.
- Panel core and insulation target
- External coating and corrosion resistance
- Compatible fasteners, sealants and trims
Plan inspection and maintenance access
Details that can be inspected and maintained are easier to manage over the building life. The project brief should identify access constraints and any areas exposed to frequent washdown or aggressive internal conditions.
