As it happens the next generation of EIFS has learned a lot from the last generation
From 1969 to about the year 2000 was the first generation of EIFS where the EIFS foam was installed directly to the substrate of a house. Where the EIFS exterior itself was the weather barrier. Before the year 2000 building codes did not require a secondary moisture barrier. The IRC (International Residential Code) in 2000 required this secondary moisture barrier on all sidings used over wood framed construction. The problem with the EIFS itself being the water barrier is that when any moisture infiltrated the system there was nowhere for it to escape. A properly installed first generation EIFS application that has been maintained has a very good chance of not having any problems. The EIFS can be done right, and the caulk and sealants maintained over the years, and still a window or roof leak can cause major damage over time on a first generation EIFS home. However, you can still have a first generation EIFS home inspected, and after passing the inspection get a warranty on the home through The Moisture Warranty Corporation.
The Next Generation of EIFS has grown and learned from the past along with the entire building industry. The unprecedented testing done has helped many industries, and has had an impact on the building codes. With the addition of a Air/Water barrier to the EIFS process has made significant improvements to the overall performance of EIFS, and is now mandatory on all wood framed construction whether you are using EIFS or not. The next generation of EIFS has been proven to drain water effectively. This overcomes the major issue with first generation EIFS.
The Next Generation of EIFS is a superior material, and out preformed all other exterior wall claddings (including brick, stucco, concrete block, and cementitous fiber board siding) in the Hygrothermal Performance testing by Oak Ridge National Laboratory, which was funded by The US Department of Energy and EIMA. A study by The National Institute of Standards and Technology (NIST) shows that over a 50 year life cycle of a building, the carbon footprint of EIFS is 1770 compared to brick at 8303. We are talking some huge numbers here, as Dryvit, one of the leading manufacturers, boast ‘over 2 billion square feet of EIFS applied’ you can begin to imagine what a positive impact having such a smaller carbon footprint has had on the environment.
Benefits of The Next Generation of EIFS – Superior Cladding
- Thermal bridging virtually eliminated
- Improved IAQ (Indoor Air Quality)
- Improved overall energy performance of a building
- Helps keep structural members at a consistent temperature, which extends life expectancy
- The constant temperature helps structure member movement and stress from temperature swings that lead to cracking in concrete and stucco walls.
- Dewpoint is eliminated
- Vapor diffusion from condensation is minimized
- Deterioration of batt insulation from condensation is minimized
- Mold growth due to condensation is virtually eliminated
- Rusting of metal fasteners and framing from condensation is minimized QR scanner online
- EIFS has low levels of volatile organic compounds as know as VOC’s
- EIFS carbon footprint is 5 times smaller than brick
- EIFS saves money in construction costs
- EIFS is more energy efficient
- ASHRAE (American Association of Heating, Refrigeration, and Air-conditioning Engineers) Standard provides minimum requirements for energy efficient design of buildings – EIFS meets these requirements
- According to ASHRAE 90.1 2001 – 2 inches of EIFS offers the equivalent energy efficiency performance of 8 inches of fiberglass insulation in a wall cavity.
- EIFS puts the continuous insulation on the outside of the building where insulation works best.
- EIFS is in the International Building Code and the International Residential Code
- EIFS provides the continuous insulation (CI) described in ASHRAE 90.1, which is required by the International Energy Conservation Code (IECC)
- EIFS can contribute to LEED certification
- EIFS is the only cladding that has an air-barrier, insulation and aesthetics all in one system, which is installed by a single contractor, with a single warranty
- EIFS has a very low Global Warming impact, where brick has a very high Global Warming Impact
