EIFS

Question 1

What does EIFS stand for?

Answer 1

External Insulation and Finishing System

Question 2

What is EIFS?

Answer 2

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.

Question 3

What are some advantages of EIFS?

Answer 3

• 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

Question 4

What are some disadvantages of EIFS?

Answer 4

• 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

Question 5

Name some issues that arise when it is installed at ground level when it comes to EIFS.

Answer 5

• Maintenance
• Vandalism
• Shoveling
• Lawn cutting

Question 6

What are the 2 types of EIFS?

Answer 6

• Barrier EIFS: Most common and basic, also known as traditional/conventional EIFS.
• EIFS with drainage: Basically the same as EIFS but with drainage capability.

Question 7

Why is EIFS a popular material?

Answer 7

• Provides a ‘modern’ seamless look
• Reasonable cost
• Ability to mimic other materials
• High-energy efficiency

Question 8

Installation of EIFS with drainage.

Answer 8

• 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

Question 9

What ‘legal problems’ come with EIFS?

Answer 9

EIFS systems are the subject of many lawsuits usually related to the installation process that caused moisture to build up and cause mould growth.
