Parex EIFS is Greener

  Subscribe to FREE newsletter  Dec 19, 2015


With building codes driving higher standards for more sustainable buildings and new green building initiatives on the rise, architects and builders are becoming more discerning about the building materials they specify for their projects. Exterior Insulation and Finish Systems (EIFS) offer the ideal solution to help meet the most stringent energy requirements in the country. EIFS is engineered to be a high-performance energy efficient exterior cladding solution. In essence, EIFS wraps your building in a thermal blanket by incorporating a continuous layer of insulation around the exterior sheathing of a building, and can be used in conjunction with liquid-applied air & waterresistive barriers to maximize building envelope performance and improve indoor air quality. This helps eliminate thermal bridging and increases R-values. EIFS is proven to be 84% more energy efficient than other exterior claddings.

Continuous insulation is a key component to an energy efficient structure. In conventional wall frame construction, batt insulation is placed inside the stud space to create a thermal barrier. To improve thermal resistance, stud thickness is often increased to allow for thicker insulation to be used. However, studs are exposed to both inside and outside environments and conduct heat at a much higher rate than the insulation which creates numerous thermal breaks, and reduces the overall effectiveness of the thermal barrier. In an EIF system, the insulation is placed on the exterior of a structure, which significantly reduces thermal breaks.


R-value measures the difficulty for energy to move through a wall assembly. The higher the R-value, the more resistant it is to energy movement through the wall. The more resistant the wall assembly, the less a structure’s HVAC system has to work which saves energy consumption and money.

Research conducted by the Oak Ridge National Laboratory and supported by the Department of Energy proves that EIFS provides superior R-value when compared to brick, stucco, and cementitious fiberboard siding.

EIFS is lighter weight than any other exterior cladding. This lightweight system means less structural engineering and ultimately a reduction in materials consumed and total energy consumption.
