Recognizing it can sometimes be difficult to locate a specific resource when there is a large volume of content, we’ve curated library pages on the most prevalent subjects of interest as they relate to continuous insulation. These topical library pages pull together the most relevant articles, news items, best practices and other online resources on each topic.

When used along with joint sealing tapes, flashing materials, and sealants, nearly all foam sheathings meet code requirements for use as continuous air barriers. 

Top Resources for using Foam Sheathing as an Air Barrier Material in an Air Barrier Assembly:

 

Continuous insulation is an excellent addition to foundations. By isolating the foundation from the ground, foam sheathing limits thermal bridging and improves building performance, both from an energy standpoint as well as moisture management. All of this means greater building efficiency, occupant comfort, and code compliance.

Don't forget your hat. With increased insulation requirements in recent versions of the energy codes, continuous insulation on the roof can allow the owner to meet thermal insulation requirements in both low-slope roofs as well as cathedral ceilings and conditioned attics.

When it comes to walls, the use of continuous insulation can greatly improve performance and simplify design and installation.  In particular, foam plastic insulating sheathing (FPIS) products can serve as an air barrier, water resistant barrier, water vapor control/retarder, and cut down on the detrimental effects of thermal bridging.

Top Resources for Commercial Walls:

 

Windows can easily coexist with exterior continuous insulation of many thicknesses. With a whole building analysis, increasing the level of continuous insulation can allow for larger windows while maintaining the same level of overall building thermal performance. Modern detailing methods improve moisture management around fenestration openings.

Don't forget your hat. With increased insulation requirements in recent versions of the energy codes, continuous insulation on the roof can allow the owner to meet thermal insulation requirements in low- and steep-sloped roof applications with the following benefits: minimizes thermal bridging through roof framing, reduces energy losses through ductwork located in unvented conditioned attics, turns attics into living space or climate-controlled storage areas, and helps protect against moisture or condensation.

Walls using foam sheathing can meet all structural code requirements with simple specification and planning.

Top Resources for Attaching Cladding through Foam Sheathing to Steel Framing:

 

Foam sheathing can be used in a variety of buildings and assemblies requiring fire resistance, where properly tested. Below find resources for using foam sheathing in fire rated applications.

Foam sheathing is a very effective means of insulating the interior or exterior of foundation walls, preventing heat loss and lowering the risk of condensation issues. Use of foam sheathing on foundations for frost protection can save thousands of dollars in construction cost and energy bills.

Engineering, according to ABET (Accreditation Board for Engineering and Technology) is "the professsion in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind."

While thermal bridges deliver a severe hit to the overall performance of an assembly, thermal breaks using continuous insulation can help mitigate the damage. 

 

Top Resources for Using Foam to Prevent Thermal Bridging:

 

With high R-values per inch, improving thermal insulation is one of the best uses of foam sheathing. 

While cats often find shelter on their own, sometimes cold climates cause cats to seek shelter in human environments such as cars and basements which may not be safe or desirable. Other times, cats are unable to find a safe place out of the rain or snow. Either way, providing an insulated shelter is something you can do right meow to help out a cat in your neighborhood. Foam sheathing continuous insulation is purrrrfect for creating well-insulated and dry shelters for cats during the winter months. 

Taped foam sheathing can be used as an effective and durable water resisitive barrier, meeting code requirements without the extra cost or labor associated with using a separate WRB product, solving the stucco moisture problem with CI. 

Top Resources for Using Foam as a Water Resistive Barrier:

 

Exterior foam sheathing provides one of the most robust and reliable methods of managing water vapor to properly balance wetting and drying potential with appropriate application of vapor retarders in coordination with insulation strategies using foam sheathing alone (e.g., the “perfect wall”) or in combination with cavity insulation.
