Alternatives to EIFS

There are various alternative models for EIFS and Retrofit Systems. EIFS systems have clear benefits in comparison to these alternatives and are the best solution for retrofit projects. The table below highlights the risks and inconveniences of the alternatives to EIFS.

Alternatives to EIFS
Alternative Systems Risks & Inconveniences of alternatives to EIFS Benefits of EIFS compared to alternatives
 

Interior Insulation

 

Reduces indoor space Does not reduce indoor space since it is installed on the exterior façade
Occupants need to move out during installation Occupants do not need to move out during installation
Creates thermal bridges which can transfer heat Does not create thermal bridges
 

Aluminum Composite Panels (ACP)

 

Fire Safety risk since it uses flammable base materials Uses fire retardant base materials
Limited colour options Virtually unlimited colour and finish options
Poor energy efficiency Extremely good energy efficiency with a saving of up to 50%
Poor insulation Extremely good heat and cold insulation
Less design flexibility Very high design flexibility
 

Autoclaved Lightweight Concrete (ALC)

 

Poor water vapour resistance Excellent resistance to water vapour and liquid water
Surface plaster can crack easily Excellent crack resistance with flexible exterior coatings
Brittle Excellent Durability
Limited thermal efficiency Excellent thermal efficiency
 

Fiber Cement

 

Absorbs and retains moisture Good vapour permeability does not retain moisture
Poor energy efficiency Excellent energy efficiency
Difficult to install Easy to install and repair
Requires regular maintenance Requires very little maintenance
Joints tend to crack due to thermal movement Does not crack regardless of climatic variations
 

Cavity Wall Insulation

 

Difficult to ensure cavity is filled. Hence can cause thermal bridging No thermal bridging possibility
Easy damp penetration Resistant to damp penetration
Can cause mould growth indoors Does not cause mould indoors
