Exterior Insulation and Finish Systems (EIFS) are a relatively new cladding system that combine a finish with a layer of exterior insulation. The finish is comprised of polymeric (organic) bonded aggregate and cement reinforced with a glass mesh.
What is the difference between EIFS and stucco?
Unlike traditional stucco that utilizes natural ingredients and mesh, External Insulation and Finishing Systems (EIFS) stucco uses layers that add in synthetic materials. … When such layers are applied, EIFS provides more protection and insulation than traditional stucco—but it also comes with some risks.
What type of foam is used in EIFS?
Polyisocyanurate (or polyiso) foam is also used in EIFS. It is used mostly on wood-frame homes. It is a thermosetting type of foam plastic insulation.
What is EIFS construction material?
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.Is EIFS a cement?
Fiber Cement. EIFS features a few benefits that help with building protection: It doesn’t crack like stucco exteriors are prone to do, it’s more energy-efficient than other building systems, and it can be designed with arch details and other decorative accents to make your building stand out.
When did they stop using EIFS?
Future homeowners loved the look of the EIFS houses. The recession of 1990 was the only thing that slowed down the business as the EIFS industry’s sales dropped for the first time in 1991. But the business rebounded in 1992 and the EIFS residential business continued to grow—that is until it ran into the perfect storm.
Does EIFS have one coat stucco?
The three wall systems that are widely accepted today are: traditional three- coat stucco; one coat fiber reinforced stucco (FRS); and exterior insulation and finish systems (EIFS).
What is efface in construction?
Exterior insulation and finish system (EIFS) is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system.Is EIFS a vapor barrier?
When you install EIFS on the exterior wall, it acts as a vapor barrier on the cold side of that wall. When fiberglass-batt insulation is then installed in the wall cavity, condensation occurs inside the wall at the (substrate) sheathing when a contrast in temperature exists from inside to outside.
Is EPS the same as EIFS?EPS is no different, although EIFS-grade and non EIFS-grade EPS is available. The requirements EPS needs to meet when being used in EIFS are important to be aware of and to follow for a sound application.
Article first time published onWhat is EPS in foam?
Expanded Polystyrene ( EPS ) is a lightweight cellular plastic material consisting of small hollow spherical balls. It is this closed cellular construction that gives EPS its remarkable characteristics. EPS is produced in a wide range of densities providing a varying range of physical properties.
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.
Is EIFS stucco still used?
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.
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.
What is the difference between synthetic and hard-coat stucco?
Synthetic EIFS stucco is slightly more energy-efficient than old-school hard-coat stucco, offering better insulation, though it’s more complicated and expensive to install. Hard-coat stucco holds up better to water, making it a good choice for areas with plenty of moisture.
Does EIFS use wire mesh?
The Installation Process Stucco and EIFS are installed in two different ways. When installing stucco, a wire mesh structure is created. … On the other hand, EIFS uses a baseboard that is installed in the desired location. In most cases, this board will be made of styrofoam.
How can you tell EIFS stucco?
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.
Can I 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.
Is EIFS synthetic stucco?
Synthetic stucco is commonly referred to as Exterior Insulating and Finish System (EIFS). Homes with this exterior finish are often strikingly beautiful, offer great flexibility in home design, and provide energy savings.
Should I replace EIFS?
While moisture can get behind just about any exterior surface on a home, the plastic nature of the EIFS synthetic stucco coatings tends to trap moisture. This trapped moisture is the match that lights the mold growth and wood rot fuse. … The EIFS synthetic stucco system must be removed for any number of reasons.
Can EIFS be repaired?
The damage to the EIFS system may be the result of intentional vandalism, unintentional damage resulting from traffic, landscaping activities etc, or weather phenomenon such as blowing debris, heavy hail etc. Holes or other damage is easily repaired with Terraco Styrobond HB DP – less than 50 mm in diameter.
What is the R value of EIFS?
Most EIFS use insulation board with an R-value of R-4 to R-5.6 per inch as the innermost layer in the wall system.
Is EIFS waterproof?
Originally, EIFS were designed as a ‘perfect barrier’ system—one which provides waterproofing protection at the exterior face of the cladding. The idea of barrier cladding assemblies is to create a face-sealed façade that repels moisture to keep the building dry.
How thick is stucco or EIFS?
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).
What causes EIFS to crack?
Causes of cracking include structural movement, stress at points requiring extra reinforcement, stresses requiring relief by expansion joints, base coat in between insulation board edges, and excessive thickness of base coat.
What is InsulFoam made of?
InsulFoam FL (Flute-Filler) is a custom-made, engineered insulation consisting of a superior closed-cell, lightweight expanded polystyrene (EPS).
Is Styrofoam an XPS?
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called “Blue Board”, manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier.
Is polystyrene open or closed cell?
Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material.
Is Thermocol a Styrofoam?
Thermocol is an EPS (Expanded Polystyrene) and Styrofoam is an XPS (Extruded Polystyrene). Both these polystyrene products are derived from petroleum, just like plastic. Thermocol is so popular that any EPS/XPS is generically called ‘Thermocol’, in the same way that photocopies are called ‘Xerox’.
Is Styrofoam a plastic?
The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that’s often used to make clear products like food packaging or lab equipment.
What is the difference between Styrofoam and Styrotex?
Polystyrene is a synthetic aromatic hydrocarbon polymer whereas Styrofoam is a trademark brand of polystyrene. This makes the difference between polystyrene and Styrofoam. … But various forms of polystyrene have different colors because of adding colorants. For example, Styrofoam has a light blue color.
