EIFS is much more flexible than traditional rigid cladding systems.
This allows the cladding to better accommodate building movement and prevent cracks from occurring. It also reduces the number of required joints within the system.
EIFS weighs significantly less than many traditional cladding products, such as stucco or masonry facades.
An EIFS assembly can weigh as little as 0.50 Kg/ft2 (one-inch thickness) creating a much lower 'dead load' applied to the exterior of a building. This is an important consideration for high-rise construction.
The lightweight characteristic of EIFS is also very beneficial when used in retrofit applications and in areas where seismic activity may be of concern.
RESISTANCE TO MOISTURE PENETRATION
EIFS finish coats are available in an unlimited range of colours and in a large variety of textures. Custom colour matching allows building owners to choose specific corporate colours, or unique one-of-a-kind colours for their projects.
EIFS also has the ability to be shaped and cut into a variety of designs. It can recreate the design of Roman columns, arches, quoins, etc. without the added weight of framing and the use of heavier construction materials. The design possibilities are only limited by the designer's imagination.
EIFS are manufactured to perform as effective barriers against moisture intrusion. Today, EIFS contain two barrier coatings to prevent moisture ingress. The first is the EIFS lamina, composed of the basecoat, mesh, and finish coat.
The second line of defence is the weather resistant barrier (WRB) located directly over the sheathing/substrate. This secondary barrier may be vapour permeable (breathable) or it may be a vapour retarder (non-breathable) depending upon wall performance requirements.
