As today's demand for a unique, good-looking product grows, customers are also increasingly concerned with long-term quality and performance. Evergreen House, Inc., has tested its system both as a standard product and for ability to meet custom, per-project requirements.

The following tests and certifications are readily available:

ASTM E283-91 Air Infiltration
ASTM E331-96 Water Resistance
ASTM E330-90 Structural Load
Complete NFRC Certification

Evergreen House has been a leader in NFRC certification for commercial site-built structures. We have developed a strong working relationship with the NFRC, the local testing agency, and the local building departments to develop standards and methodologies for reaching certification standards, while meeting the Washington State Energy Codes. Certification listings and labels are available for all Evergreen House product lines.
