How thick is EIFS coating?

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.

How thick is EIFS finish?

The entire thickness of the EIFS system is typically, approximately 1/8"to 1/4", plus the thickness of the insulation board, which will vary, based upon desired R-value (insulation rating).

How thick should EIFS be?

Generally the minimum thickness of EPS for Dryvit EIFS is 1 inch. Locally, where clearance may be an issue (window and door returns, etc.). 3/4 inch thickness is acceptable.

How many layers are in an EIFS?

There are 3 layers to EIFS, the Inner, Middle, and Exterior layers. The Inner layer is made up of Expanded Polystyrene (EPS) board that is secured to the wall surface with an adhesive.

What is EIFS coating?

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.

(EIFS) finish coat

When did builders stop using EIFS?

EIFS has been in use since the 1960s in North America, first on masonry buildings, but since the 1990s the majority on wood-framed buildings.

What is the difference between stucco and EIFS?

What is EIFS? Unlike traditional stucco that utilizes natural ingredients and mesh, External Insulation and Finishing Systems (EIFS) stucco uses layers that add in synthetic materials. The first layer is comprised of a polystyrene foam board. Then, that is followed by a fiberglass mesh and a finishing coat.

What is behind EIFS?

Wall drainage EIFS systems are similar to cavity walls; they are installed over a weather barrier behind the insulation that acts as a secondary drainage plane.

How long does EIFS stucco 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.

Is EIFS acrylic stucco?

EIFS stucco refers to Exterior Insulation and Finish System, also called synthetic stucco. It's made of acrylic and applied in several 1/8” layers over polystyrene or some other insulation board on top of plywood or some other exterior sheathing.

What thickness is rigid insulation?

Rigid board insulation generally comes in standard thicknesses ranging from ½ inch to 2 inches. It is possible for homes located in extreme climates to order specialty thicknesses of up to 6 inches directly from certain manufacturers. Obviously, the thicker the rigid board, the higher the insulation capacities.

Can EIFS be applied over stucco?

StoTherm EIFS can be installed over the glass-mat gypsum sheathing, wood-based sheathing, plywood, oriented strand board (OSB), masonry, plaster, concrete or stucco.

Can you apply stucco over EIFS?

"Stucco" can be installed over foam insulation, like EIFS.

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.

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.

Does EIFS require expansion joints?

Expansion joints in EIFS are required at the following locations: where they exist in the substrate or supporting construction. where the EIFS adjoins dissimilar construction or materials. at changes in building height or other areas of anticipated building movement.

Can you recoat EIFS?

Introduction The appearance of EIFS walls can be quickly refreshed by applying an appropriate coating. BASF COLOR COAT is specifically formulated for EIFS. This 100% acrylic coating minimizes changes to existing finishes.

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.

Is it OK to paint EIFS?

Painting or recoating EIFS is normally unnecessary unless a color change is wanted or unusually stubborn stains cannot be removed. EIFS buildings should not be painted like most surfaces.

How is EIFS installed?

EIFS may be attached by mechanical fasteners (as shown) or by adhesive (as shown below). EIFS attached to concrete or masonry using adhesive. Mechanical fasteners may also be used. The Expanded Polystyrene Board (EPS) is placed on the wall in a running-bond pattern.

Is Dryvit the same as 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.

Can EIFS be structural?

EIFS panels can be designed to meet the aesthetic and structural demands of any commercial project.

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.

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.

What paint do you use on EIFS?

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.
