EIFS Stucco: insulation performance.
Pros:
- EIFS delivers an R-value of .07-.09 per inch (1.05 R-value at residential standard 1.5′ foam).
- Traditional stucco at industry-standard 3/4″ thickness registers a mere .02 R-value.
- Commercial EIFS applications range from 2″ to 5′ thickness with proportionally higher insulation factors.
- Drives energy costs down.
- Uses less water during installation. Non-biodegradable.
- More aesthetic: elegant & modern look to your building envelope.
- Uses acrylic aggregate finish: currently the most popular stucco finish for Calgary building and homes.
- If you opt for sand & cement system with acrylic finish without the insulation, it will prevent woodpecker from pecking and nesting in.
Cons:
- Pricier than sand & cement stucco system: currently between $12-$16 per sqft.
- Prone to woodpecker damage. Woodpecker leverage the foam to nest in.
- Repairs will look patchy and harder to blend in when repairing an larger area.
Pro tip: always opt for ADEX A/B woodpecker-proof stucco system for insulated stucco system. It's worth the extra cost. Otherwise, you'll end up with patchy stucco and pay for repairs.
