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.
Zero energy school construction is a growing trend across the country. A combination of advanced energy efficiency strategies, affordable solar power and an innovative concrete building system called Insulating Concrete Forms (ICFs) is making it possible. ICFs combine the strength and durability of reinforced concrete with the versatility and energy efficiency of rigid insulation.
The course identifies what stone wool insulation is and how it is produced. It discusses mineral wool in Commercial applications with an emphasis on Rainscreen cladding design and in exterior cavity walls. It highlights key benefits when used in the field versus some of the other insulating materials traditionally used in the market today as it pertains to NFPA 285 requirements and new ASHRAE 90.1 2010 continuous cavity insulation requirements.
This course covers the latest in building enclosure technology for energy efficient buildings. It provides an in-depth discussion of emerging wall systems that provide durable, cost effective and thermally efficient performance.
The seminar will cover all building types and construction materials, with a few highlights and lessons learned from building science researchers.
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.
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.
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.
Green building is about architectural and human performance and LEED v4 and other green programs can drive market transformation. This course demonstrates how LEEDïƒ’ requirements are changing to increasingly emphasize materials and health, and how new credits with higher standards for health and performance are raising the bar for project teams and the sustainable buildings they design. Case studies where insulation products were used in green buildings will be discussed.
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.
Wall assembly components such as CI and WRBs are now required across the country, requiring in-depth understanding of wall systems. Improper design of transition details can lead to detrimental and expensive issues in wall assemblies. This course reviews building science fundamentals for complete wall systems with CI and WRBs, important considerations when designing transitions and penetrations, and common issues that arise from errors in sequencing, material compatibility and design verification.
