TECHNICAL BULLETINS

Looking for detailed information on specific technical topics? PIMA Technical Bulletins provide in-depth data related to a wide variety of technical issues, including application methods, energy performance, moisture dynamics, and fire resistance.

Polysio Insulation in Masonry Cavity Walls

(PIMA Technical Bulletin 401). This technical bulletin reviews the role of polyiso insulation in a masonry cavity wall. 

Polysio Insulation and Water Absorption: Does Moisture Matter?

(PIMA Technical Bulletin 402). This technical bulletin reviews the role of the cavity wall as a moisture-deterrent and how polyiso insulation can help. 

Continuous Insulation Using Polyiso Wall Sheathing

(PIMA Technical Bulletin 403). This technical bulletin reviews the role of the cavity wall as a moisture-deterrent and how polyiso insulation can help. 

Moisture Sorption of Building Materials

(PIMA Technical Bulletin 404). This technical bulletin provides a primer on the moisture sorption characteristics of building materials like polyiso. 

Fire Resistance Properties of Polyiso Foam Plastic Insulation Used in Wall Assemblies: Facts and Comparisons

(PIMA Technical Bulletin 405). This technical bulletin reviews the minimum fire resistance properties required for foam plastic insulation and compares data on polyiso with other recognized combustible materials. 

Fire Performance in Walls and Ceilings

(PIMA Technical Bulletin 103). This technical bulletin discusses polyiso insulation as it relates to building codes in construction and fire tests in walls and ceilings including ASTM E84 and ASTM E119.

Residential Construction Details with the WarmWall System

(PIMA Technical Bulletin 301). This technical bulletin highlights the construction details, features and benefits of the WarmWallCM System—an innovative building concept utilizing foil-faced polyiso insulation sheathing to provide a complete envelope of insulation on the exterior of a home. 

Corner Bracing with the WarmWallCM System

(PIMA Technical Bulletin 302). This technical bulletin discusses corner bracing, which is required by building codes using the WarmWallCM system. 

Moisture Control with the WarmWallCM System

(PIMA Technical Bulletin 303). This technical bulletin reviews The WarmWallCM system and the important benefit that it provides—moisture control. The bulletin also reviews the problems that can arise as a result of too much moisture in a wall cavity. 

Energy Efficiency with the WarmWallCM System

(PIMA Technical Bulletin 304). This technical bulletin discusses energy efficiency within the WarmWallCM system, specifically its ability to reduce energy loss in all wall locations, not just the stud cavities.
