Addressing Moisture and Temperature Concerns in Unvented Attics that Have Spray Foam Insulation

Unvented attic construction using spray foam insulation is a fairly new approach in home building. With it the orientation and type of insulation applied to the top of the building enclosure has changed from the traditional way. Temperature and moisture conditions experienced by various assembly elements will be impacted. In this whitepaper, we will address concerns some in the building industry have expressed with this construction approach.

Keep a Tight Lid on It

Allotting for installation of an HVAC system within the thermal envelope is a key maximize a building’s space and minimize air leakage to the outside. Using spray foam insulation within an unvented attic creates a continuous air barrier and insulation layer that saves energy and money. Spray foam insulation (both open-cell and closed-cell) adds structural strength, sound-dampening qualities, high R-value, and the control of outdoor pollutants for both commercial and residential buildings.

Spray Polyurethane Foam – The Evolution of Building Insulation

Of all the different insulation options available today in commercial construction, spray foam can provide outstanding thermal performance while also contributing to air sealing, moisture control, and even structural integrity.

This learning unit will provide an overview of spray foam insulation, how it differs from conventional insulation types, its most appropriate applications, and how the material is allowed to be used in fire-resistant construction.

How Spray Foam Insulation Controls Moisture in Exterior Wall Applications

Research has shown that exterior cladding materials on an exterior wall can prevent most, but not all, moisture from entering into a wall. Having a backup control system behind the cladding to control moisture by shedding it to the exterior is important for the long term durability of an exterior wall. A significant component of the backup moisture control system is often called by building envelope designers a drainage plane or a water resistive barrier (WRB). See how Spray Foam Insulation can act as a WRB and help control moisure in wall applications.

Moisture Control and More with Spray Foam Insulation

In the design of building enclosures an emerging alternative is the use of spray foam insulation as exterior continuous insulation featuring the ability to resist heat, water, vapor and air movement in an uninterrupted, continuous performance installation. A significant outcome is the control of moisture mechanisms in buildings.

How spray foam insulation’s water resistive, air barrier and insulation characteristics help to control moisture is examined in detail. That it is a proven option that offers such performance in addition to allowing for design freedom and flexible installation is also discussed.

The Performance Benefits of using Medium Density Spray Foam in Continuous Insulation Applications

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.
