DuraTemp vs. LP SmartSide: Which Shed Siding Is Better?
If you’re comparing DuraTemp vs. LP SmartSide, you’re likely trying to answer one simple question:
Which siding will last longer on my shed—especially in a climate like Indiana?
Here’s the honest answer:
Both are good products. But they’re built differently, and those differences matter over time.
Quick Answer
- Choose DuraTemp if you want durability, lower maintenance risk, and better long-term performance
- Choose LP SmartSide if you want better looks and more design options—and are willing to maintain it carefully
What Is the Difference Between DuraTemp and LP SmartSide?
DuraTemp Siding
- Plywood core (cross-laminated)
- Hardboard outer face
- Strong, impact-resistant, and more forgiving with moisture
LP SmartSide Siding
- OSB (engineered wood strand) core
- Treated with zinc borate for pests and rot
- More refined, cedar-like appearance
Which One Is Better for Indiana Weather?
Indiana’s climate brings:
- High humidity
- Freezing winters
- Freeze–thaw cycles
These conditions expose weaknesses in siding—especially at edges and joints.
DuraTemp performs better in these conditions overall because:
- Plywood handles moisture more gradually
- It’s less sensitive to small installation or maintenance mistakes
LP SmartSide can perform well—but only if installed and maintained correctly.
Common Problems with LP SmartSide
LP SmartSide is a solid product, but it has a few important requirements:
- All cut edges must be sealed or moisture can get in
- Expansion gaps must be correct or panels can buckle
- Paint must be maintained to prevent swelling or damage
If these steps are skipped, problems can show up faster—especially in wet climates.
Downsides of DuraTemp
To be fair, DuraTemp has a few trade-offs:
- More basic, traditional appearance
- Fewer style options
- No built-in pest treatment
Cost Comparison
- DuraTemp: ~$45–$55 per sheet
- LP SmartSide: ~$60–$75 per sheet
On a typical shed, DuraTemp is usually $150–$250 cheaper in materials.
How Long Does Each One Last?
With proper maintenance in Indiana:
- DuraTemp: 30–50+ years (repaint every 8–12 years)
- LP SmartSide: 25–40+ years (repaint every 5–10 years)
Neglect either one, and issues can start within 5–10 years.
Final Verdict
There’s no one-size-fits-all answer—but here’s the reality:
- DuraTemp is the better choice for long-term durability and lower risk
- LP SmartSide is the better choice for appearance and design flexibility
