The Value of EIFS Exterior Insulation

ProCoat - November 27, 2017

eifs exterior insulation

EIFS (Exterior Insulation and Finish Systems) has been around for decades. During that time, the methods and materials have evolved into a state-of-the-art cladding system that is growing in popularity worldwide. The system consists of scientifically designed layers that coordinate to minimize energy loss while resisting moisture absorption. EIFS claddings create an energy-efficient and durable structure that reduces long-term operating costs while providing an attractive exterior appearance.

Since up to 55% of energy loss passes through building walls, EIFS systems create a superior R-value, the measurement of the resistance of heat loss, in buildings and homes. The combination of the insulation board used in EIFS, plus the high-tech wall insulating materials and built-in moisture evacuation cavity, will create a wall rated up to R16, a significant improvement over standard insulation.

New Construction Benefits

The energy saving benefit of a newly constructed building does not simply stop with restricting the loss of heat. Additionally, owners can install smaller capacity furnaces and air conditioners to handle the reduced demand. As a result, less electricity or gas will be used to keep the building comfortable.

Exterior Durability and Reduced Maintenance

EIFS exterior insulation consists of a water-resistant base coat to serve as a weather barrier, followed by a colorfast and crack-resistant polymer surface material. Unlike some other exteriors, the material is resistant to fading, yellowing, and chalking. As a result, today’s EIFS rarely needs repainting.

Also, the outer surface resists dirt, mildew, and mold. If these surfaces should become dirty, they can be cleaned easily with a water hose.

Moisture Control

During the early evolution of EIFS exterior insulation, moisture absorption due to high humidity and excessive rainfall was a problem. Since then, developers have altered the layering structure to include more water resistant materials. Also, an open cavity in the midst of the insulating layers allows for complete moisture evaporation and drainage. Improved exterior finishes plus better sealing processes at seams and gaps have eliminated the water problem.

With current techniques, EIFS has better moisture management than other types of claddings including stucco, wood, brick, or stone.

Fire Resistance

EIFS meets or exceeds all fire code requirements. EIFS exterior insulation is  certified for fire resistance, ignitability, intermediate multi-story testing, and flame spreading resistance.
