How are EIFS installed?

EIFS installation

EIFS are typically attached to the outside face of exterior walls with an adhesive (cementitious or acrylic based) or mechanical fasteners. Adhesives are commonly used to attach EIFS to gypsum board, cement board, or concrete substrates.

How does EIFS system work?

An Exterior Insulation Finishing System (EIFS), also known as EWI (Exterior Wall Insulation Systems) or External Thermal Insulation Composite Systems (ETICS) is a type of cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system.

Can you install EIFS over stucco?

Substrates. StoTherm EIFS can be installed over the glass-mat gypsum sheathing, wood-based sheathing, plywood, oriented strand board (OSB), masonry, plaster, concrete or stucco. The key element of EIFS is to ensure there is no moisture accumulation not contaminants within the systems.

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 many years does EIFS last?

A. 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.

Exterior Insulation Finish System (EIFS)

Do people still use EIFS?

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.

Can you pressure wash EIFS?

The best way to clean EIFS is to use high water volume coupled with low water pressure and non-abrasive cleaners. Do not use caustic chemicals or abrasive cleaning techniques, which will permanently damage the finish.

What is better EIFS or 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.

How can you tell the difference between stucco and EIFS?

Go outside and knock on an outer “stucco” wall of your home. If it sounds hollow, there is a good chance you have EIFS. If it feels like you are knocking on a brick wall, it is more likely that you are knocking on traditional “hard-coat” stucco.

What is the difference between Dryvit and EIFS?

Having a house with EIFS, also known as Dryvit, isn't the end of the world. EIFS isn't a disease; it's synthetic stucco. And even though your house may have been built using it, with knowledge and proper maintenance everything can be just fine. EIFS is an Exterior Insulation and Finish System.

How thick is EIFS system?

The total thickness of EIFS “Lamina” is generally 1/16” to 1/8” but can be thicker in areas of high-impact, by using high impact resistant mesh. Similar to stucco it is important to follow a proper design by a registered design professional or the EIFS manufacturer.

Why should barrier wall EIFS be avoided?

MOISTURE ISSUES

The barrier in any EIF system is the basecoat and mesh layer. This layer will not allow the penetration of moisture and functions as the moisture-intrusion-preventing workhorse of the system.

Should I replace EIFS?

EIFS Replacement Advantages: Replacing your EIFS siding has many advantages including; Eliminating a failed system that allows for moisture intrusion, mold and dry rot damage and replacing it with proven siding that is built to last for 30 years or more.

What is the EFIS system?

An Electronic Flight Instrument System (EFIS) is a flight deck instrument display system in which the display technology used is electronic rather than electromechanical. Early EFIS systems portray information using cathode ray tube (CRT) technology.

What is an EIFS ceiling?

A: According to EIMA, exterior insulation and finish system (pronounced “eefs”) is a non-load bearing, exterior wall cladding system consisting of an insulation board, attached either adhesively or mechanically, or both, to the substrate; an integrally reinforced basecoat; and a textured protective finish coat.

How do you tell if your house is 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.

Does EIFS use wire mesh?

Durability of EIFS

Within the several layers and materials required for an efficient EIFS cladding is a durable mesh material. The Exterior Design Institute recommends a high-impact, reinforcing mesh that is double-strand, interwoven glass fiber.

Can EIFS stucco be painted?

On a side note, EIFS can be painted just like traditional stucco. Depending on the characteristics and appearance wanted, our professional commercial paint contractors use either top-quality acrylic latex paints or elastomeric coating systems.

What is the R-value of EIFS?

EIFS is an adhesively attached insulating cladding system. There are no fastening penetrations to the insulating component of these systems, the expanded Polystyrene Foam. This foam has an R value of approximately 4-per-inch of thickness at a 1-pound density.

What is the problem with synthetic stucco?

Severe Synthetic Stucco Problems

Delamination, which is synthetic stucco detaching from your home's exterior. Rotting of wood beams and trim. Mold and mildew growth, both on interior walls and beneath on the home's base walls. Infestation of termites and other moisture seeking insects.

Does stucco add R-value?

Energy Efficient

The continuous insulation, uninterrupted by interior studs that act as a thermal bridge, can significantly increase the R-value of the walls to which it is applied. Stucco, at roughly an inch thick, offers an R-value of about . 20.

Should you paint EIFS?

Unlike wood, stucco and other siding materials, EIFS rarely need painting. Most EIFS systems are specifically formulated with 100% acrylic binder, which gives EIFS superior resistance to fading, chalking and yellowing. As a result, the systems tend to maintain their original appearance over time.

How do you maintain synthetic stucco?

Use gentle pressure and scrubbing to keep your synthetic stucco durable and resistant to wear. Regular cleaning with the proper technique can ensure your synthetic stucco finish looks its best. Fill a pump sprayer with 1 qt. chlorine bleach and 1 cup trisodium phosphate per gallon of warm water.

Does Dryvit need to be sealed?

Contact Dryvit for information. Maintaining a weathertight seal around windows and doors is very important for any exterior cladding, whether it's clapboard, shingles, stucco, brick or a Dryvit system.
