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.
Allotting for installation of an HVAC system within the thermal envelope is a key maximize a buildingâ€™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.
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.
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 insulationâ€™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.
Updates to building codes plus consumer demand for energy-efficient homes presents an opportunity to position your homes above the rest. Get the most bang for your buck. In this webinar, learn what areas are worth it to focus on when you go above and beyond the energy codes.
The design of exterior wall assemblies has become increasingly focused on performance for greater energy efficiency and resistance to air and water penetration. The 2015 International Energy Conservation Code and ASHRAE 90.1 now requires insulation that is continuous in wall assemblies, (i.e. not interrupted by studs, framing, etc.) in all eight climate zones within the United States. This push for continuous insulation in exterior wall assemblies is also reflected in green building standards and the desires of building owners to reduce energy costs.
In this presentation, we will look at the performance, installation and cost advantages of medium density spray foam insulation compared to the commonly used rigid foam board in continuous insulation applications.
Open Cell Spray Foam insulation is a logical and proven choice for commercial buildings as it can reduce upfront costs by taking advantage of higher yield and also can reduce energy related operating costs for buildings. In addition to having the lowest environmental impact by being water-blown, Open Cell Spray Foam Insulation also contributes to improved indoor air quality within the building and overall building occupant comfort. Over the course of this presentation, you will learn about Open Cell Insulationâ€™s air barrier and vapor permeability, fire ratings and code compliance, ability to enhance a building's longevity, and environmental and Green Building contributions, as well as all health and safety directions, recommendations and best practices.
Spray Foam Insulation is a cost-effective, superior choice for exterior commercial wall solution for modern building design. This 3-in-1 product acts as insulation, air barrier, and vapor retarder with lower installed costs, reduced labor and less waste. The modern approach to continuous insulation smoothly and completely cover all areas of the wall assembly. Plus, our Icynene ProSeal Eco spray foam product can be used 12 months a year in all climates.
