What is EIFS?

What is EIFS

EIFS, or Exterior Insulation and Finish System, is a type of synthetic wall cladding that features an insulation board secured to your building’s exterior, a durable base coat applied over the board with glass fiber reinforcing mesh embedded in it and a finish coat which gives the finished appearance.

EIFS Construction

EIFS Construction

EIFS construction involves applying multiple layers to a building’s exterior for insulation and protection. The first layer consists of foam board or insulation board, which is securely fastened to the wall surface.

This insulation layer provides the base for two additional coats: a base coat and a finish coat. Strong mesh material is embedded into the durable polymer-modified cement base coat, adding strength and impact resistance to the system.

Lastly, an aesthetically versatile finish coat completes the process. This final layer is made from water-resistant materials, offering color and texture options while sealing out moisture.

EIFS installation requires precision and expertise due to its complex multilayered structure – yet another reason why it is often chosen for modern buildings seeking high energy efficiency.

Lastly, while synthetic stucco proves more impact-resistant than traditional stucco, heavy impacts from hail or hard objects can still cause damage needing professional repair.

What is Traditional Stucco?

What is Traditional Stucco

Traditional stucco, also known as cement stucco, is a top-notch building material made from sand, Portland cement and water. It’s well-known for its durability and unique texture. The application of traditional stucco involves layering it over lath (a support base), usually in three coats: scratch coat, brown coat and finish coat.

This exterior siding stands the test of time due to its strength but can be prone to cracking if not maintained properly.

Stucco Construction

Stucco Construction

Stucco construction involves a meticulous process to ensure durability and resistance to the elements. It starts with the application of a wire mesh over a foam board attached to the exterior wall, providing structure for the stucco mix.

A base coat is then applied followed by subsequent layers – often three in total including a finish coat. Made from portland cement, sand, lime and water, traditional stucco dries into an extremely hard and sturdy surface.

This labor-intensive procedure results in structures that can withstand harsh weather conditions while offering attractive aesthetics. However, despite stucco’s undeniable strength and stability, it may develop cracks if not correctly maintained or exposed to severe movement or stress factors like earthquakes.

Advantages of Using Stucco

Advantages of Using Stucco

Stucco is revered for its numerous benefits, especially when it comes to durability and weather resistance. Its strength often outpaces other building materials due to low water absorption and sturdy construction.

Dive into the nitty-gritty of EIFS and traditional stucco, exploring their stark differences in installation, Wall breathability, crack resistance, and maintenance routines – facets that could ultimately influence your choice between these two popular construction options.

Stay tuned to unveil more on this intriguing comparison!



The process of installing EIFS differs from that of traditional stucco. EIFS is more complex and time-consuming due to its multiple layers, including an insulating foam board layer attached to the exterior wall with adhesives or mechanical fasteners.

A base coat applied on top incorporates a mesh for reinforcement followed by a finish coat for aesthetics and weather resistance. On the other hand, traditional stucco installation involves applying three coats of cement mixture over wire lath directly onto the structural wall without any insulation layer in between.

This method makes it faster and less challenging to install than EIFS but lacks the thermal insulation benefits offered by EIFS systems.

Wall Breathability

Wall Breathability

Traditional stucco allows for wall breathability which means it lets water vapor pass through. This quality protects the building from potential moisture damage and reduces the likelihood of mold.

Traditional stucco’s porous nature functions as a natural form of ventilation, keeping interior spaces fresh and dry even in humid weather conditions.

On the other hand, EIFS is a non-porous material and does not allow moisture to migrate through its surface. However, this design limitation has been mitigated by modern EIFS versions with advanced drainage systems.

These systems help prevent water accumulation behind the cladding thereby addressing concerns related to dampness or mold formation that could compromise structural integrity over time.

Crack Resistance

Crack Resistance

The flexibility of EIFS allows it to handle small shifts in a building’s structure, helping prevent cracks that could otherwise appear. Traditional stucco, although known for its strength and resistance to the elements, is less resilient when it comes to crack prevention due to its rigid nature.

This durability factor makes EIFS a great option where weather conditions vary widely. Synthetic stucco differs from traditional stucco not only by material but also by performance, especially when it comes to resisting cracks.


Keeping your building’s exterior in top condition requires regular maintenance. Traditional stucco is rugged and enduring, usually needing minimal upkeep – a fresh coat of paint can often invigorate its appearance.

On the other hand, EIFS systems are less demanding when it comes to maintenance due to their resistance to cracks and durability brought about by multiple layers including fiberglass.

As EIFS doesn’t absorb water like traditional stucco does, issues related to moisture damage are significantly reduced. It’s important to note that although EIFS is puncture-resistant, high-impact damage could require professional repair services for optimal results.
