Is EIFS better than stucco?
The fiberglass layer provides more durability, even against hard blows from weather. EIFS is notably lighter than traditional stucco, however. It is 80-percent less heavy than stucco, but it has a higher R-value, coming in between 4 and 5.6, which is notably higher than the 0.20 R-value of regular stucco.
What are the pros and cons of using traditional stucco siding vs EIFS?
Traditional stucco is praised for its overall strength, resistance to the elements, and the fact that it is less likely to absorb water, which can cause permanent damage to buildings. Additionally, traditional stucco is usually a bit less expensive than EIFS.
Is synthetic or traditional stucco better?
Synthetic Stucco Performance. Traditional stucco is more durable, fire resistant, and has greater longevity, being able to last up to 50 years with low maintenance. Traditional stucco is also very porous and dries out quickly, while synthetic stucco is not and can have water damage issues if not installed properly.
How can you tell the difference between stucco and EIFS?
The easiest way to identify synthetic stucco (EIFS) is by touching the material with your bare hand. When you touch the wall where the stucco is installed, it will feel like plastic. You can also knock gently on the wall. If it sounds hollow and thin, you have EIFS on your home.
Why is EIFS bad?
Exterior insulation and finish systems (EIFS) earned a bad rap in the 1980s and ’90s. Water infiltration behind barrier EIFS (systems designed with no integral drainage) caused the panels to mold, buckle, delaminate, and more. Manufacturers and builders were subjected to numerous lawsuits.
What is the problem with EIFS?
The problems with barrier EIFS cladding all stem from water intrusion. These problems include moisture accumulation in the wall cavity, subsequent wood damage and, in more advanced cases, mold growth and the infestation of pests such as carpenter ants or termites.
How long does traditional stucco last?
50-80 years
Stucco is a very durable finish material with a typical life span of 50-80 years or more. Although it is one of the most durable surfaces available, it also features the lowest annual maintenance cost when compared to other siding materials. Stucco is a natural material consisting of an aggregate, a binder, and water.
Do builders still use EIFS?
In the Southwest and on the Gulf Coast, especially, EIFS—also known as synthetic stucco—appealed to builders and architects as a reliable alternative to true stucco. Yet today, EIFS are still around. About 100 million square feet of EIFS went on new and remodeled homes last year, rivaling any other siding material.
How long will EIFS last?
Dryvit EIFS are designed to last for the typical design life of a building. The actual longevity on any specific building will depend mainly on the building maintenance program. Some EIFS facades date back 50-60 years.
