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.

The Benefits of Mineral Wool Insulation

Insulation is one of the most important elements of a building. It conserves energy, reduces sound and resists fire. Mineral wool comes in many forms including batts, board, rolls, loose fill, and acoustical products and is suitable for a wide range of applications, from exterior curtain walls to interior acoustical ceiling tiles or panels.

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.

Designing with Continuous Insulation for Thermal and Moisture Management

This course discusses some basic building science fundamentals, while looking at specific code requirements in the IRC, IBC and the international energy conservation code. It addresses why some of the trade-offs and differences exist between those two sets of code requirements. Lastly, we'll work through an example and the decision making process to determine the continuous insulation and vapor retarder requirements for a project in a specific climate zone.
