How Modern Building Envelope Materials Support New Code Requirements

Contractors are pushed toward tighter, more energy-efficient building envelopes. making continuity in insulation, air sealing, and moisture control essential and increasing the importance of integrated materials like spray foam, structural sheathing, coatings, and sealants to meet rising performance standards.

Is Continuous Insulation the Solution?

How to Achieve Exceptional Thermal Performance

While continuous insulation improves wall thermal performance, DuPont's integrated structural insulated sheathing system outperforms traditional assemblies by reducing thermal bridging and preserving more of the designed R-value through advanced Clear Field U-Factor modeling.
