EIFS FAQs
The benefits of EIFS extend beyond energy efficiency and design and flexibility. The systems also are easy to maintain. EIFS rarely need painting. Most are specially formulated with a 100% acrylic binder, which helps EIFS resist fading, chalking and yellowing. As a result, most systems tend to maintain their original appearance over time. EIFS also tend to resist dirt, mildew and mold, which further contribute to keeping building exteriors looking clean and freshly painted.
WHAT ARE EIFS?
Exterior Insulation and Finish Systems (EIFS) are multi-layered exterior wall systems that are used on both commercial buildings and homes. They provide superior energy efficiency and offer much greater design flexibility than other cladding product
EIFS BEING ENERGY EFFICIENT?
EIFS acts as an energy-efficient thermal blanket. When insulating the outside of your home, EIFS can reduce air infiltration by as much as 55% compared to standard brick or wood construction, which leads to reduced energy consumption in your home. The standard wall construction has many thermal breaks where heat and cold pass through the exterior walls.
ADDING R-VALUE
EIFS adds to the “R-value” of a home or building. (R-value is a measurement of the resistance to heat flow; the higher the R-value, the better the material’s insulating value.) Most EIFS use insulation board with an R-value of R-4 to R-5.6 per inch as the innermost layer in the wall system. When combined with standard wall cavity insulation, this extra layer can boost wall insulation from R-11 to R-16 or more.
HOW LONG SHOULD EIFS LAST?
If properly maintained, the EIFS cladding will last the life of the building. Initial EIFS walls were installed in the late 1960s and most are still in good standing. Periodic cleaning is suggested to maintain the EIFS appearance. Sometime repair of impact damage or punctures of the EIFS are necessary to restore surface integrity. As with all claddings, abutting elements such as sealant and flashing should be periodically inspected and maintained.
