What is EIFS on frame?
Exterior Insulation and Finish System (EIFS) is an exterior wall coating system that resembles stucco. It incorporates a substrate covered with a foam insulation board, a reinforcing mesh, a base coat, and a finish coat of synthetic stucco material applied to a stud frame wall.
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.
What is structural EIFS?
Exterior Insulation and Finish System (EIFS) is an exterior wall cladding that utilizes rigid insulation boards on the exterior of the wall sheathing with a plaster appearance exterior skin.
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 the difference between EIFS and stucco?
EIFS is an acrylic based system applied over an insulation panel, giving an “R” value to the wall; while stucco is a cementitious based system that does not give an “R” value to the wall, since it lacks insulation.
What is EIFS finish coating?
EIFS finish coats come in a wide variety of colors and textures similar to those of stucco. Since the base coats are relatively thin, especially in PB systems, they are susceptible to impact damage. Color retention is relatively good. Common Problems for EIFS are as follows:
What is EIFS (sythetic stucco)?
An Exterior Insulation and Finish System ( a.k.a. Sythetic Stucco) is an exterior wall-cladding system comprised of insulation boards attached to a substrate, covered with a reinforced base coat, and a textured protective finish coat. EIFS was introduced in the US in the 60’s and transitioned from commercial buildings to residential homes.
What is EIFS wall insulation made of?
The insulation typically consists of extruded expanded polystyrene (XPS) and is mechanically attached to the sheathing and or wall structure. EIFS is available in two basic types: a barrier wall system or a wall drainage system. Barrier EIFS wall systems rely primarily on the base coat portion of the exterior skin to resist water penetration.
What are the problems with EIFS base coat?
Since the base coats are relatively thin, especially in PB systems, they are susceptible to impact damage. Color retention is relatively good. Common Problems for EIFS are as follows:
