What does EIFS stand for?
External Insulation and Finishing System
What is EIFS?
Non-load-bearing cladding systems provide exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system.
It is a lightweight synthetic wall cladding, also known as synthetic stucco, that includes plastic insulation ( highly combustible ) and thin synthetic coatings.
What are some advantages of EIFS?
- More energy-efficient than conventional stucco over time
- Weighs around 80% less than traditional stucco, despite the number of layers
- Flexible, making it less susceptible to damage from drastic changes in temperatures
- More durable than traditional stucco
- Can shed water and be sealed at the windows and other openings, making it hard for water to leak in
- Can be installed in a variety of textures and colors to make your home’s exterior stand out
What are some disadvantages of EIFS?
- Installation is complex and uses more materials than some other exterior finishes, so it can be expensive
- If EIFS siding needs replacement, the cost can be as high as $16 per square foot. Stucco costs an average of $6 to $9 per square foot
- EIFS layers can’t breathe, which can allow moisture to become trapped and cause damage, including mould. But this depends in part on the installation
- EIFS can require frequent inspections because of the potential for water seepage
- Can be hard to clean and may need regular pressure washing
Name some issues that arise when it is installed at ground level when it comes to EIFS.
- Maintenance
- Vandalism
- Shoveling
- Lawn cutting
What are the 2 types of EIFS?
- Barrier EIFS: Most common and basic, also known as traditional/conventional EIFS.
- EIFS with drainage: Basically the same as EIFS but with drainage capability.
Why is EIFS a popular material?
- Provides a ‘modern’ seamless look
- Reasonable cost
- Ability to mimic other materials
- High-energy efficiency
Installation of EIFS with drainage.
- Takes into account the rain-screen principle
- An airspace is established between the backup wall and the EIFS
- Composition: Backup wall, air ( weather ) barrier, air space, EIFS
What ‘legal problems’ come with EIFS?
EIFS systems are the subject of many lawsuits usually related to the installation process that caused moisture to build up and cause mould growth.
