An Introduction to ETFE Architecture (Architectural Design)

Discover why Icynene closed cell spray foam insulation offers superior performance to rigid XPS foam sheathing board... and at a lower installed cost!

The purpose of this white paper is to highlight several important performance and application facts that demonstrate why medium density spray foam is the superior choice in exterior continuous insulation applications. Findings within this white paper are based on field experience obtained on construction sites, and from testing and evaluations conducted for ICC-ES reports and Air Barrier Association of America (ABAA) programs according to appropriate industry and building code performance criteria.

Building science is an integral part of what builders use today as tools to achieve a better performance building. To achieve a better performance building, builders understand the value of building science and understand that building science will help them achieve building code targets.

Air sealing is now an important part of achieving energy efficiency, and choosing the right insulation is key to achieving air tightness and performance. To reduce air infiltration and achieve an energy-efficient building, the gaps in the building’s thermal enclosure must be sealed properly.

In today’s residential marketplace, air sealing has become a fundamental part of the home building equation, so knowing where and how to air seal will save you money, time and resources on a job. Recent data from a comprehensive industry study has yielded new insights into the role of air sealing in high performance building that can equate to savings for builders and homeowners.

Expectations for better building performance underscore the importance of air barriers for commercial-building envelopes and code compliance. Use of closed-cell spray polyurethane foam (ccSPF) as a key material in air barrier assemblies can help architects, engineers, contractors and owners/developers meet air barrier requirements more easily. CcSPF provides excellent performance characteristics and construction advantages.

A focus on green building standards and more stringent code requirements have led to the adoption of best practices in construction materials and methods. Among those is the use of more efficient insulation systems, air barriers and seamless monolithic roofing systems. Use of closed-cell spray polyurethane foam (ccSPF) can help meet the stringent requirements of modern, sustainable building design. ccSPF provides excellent performance and environmental benefits.
