The 4-Layer Insulation Strategy
What is the best way to insulate a dome?
A multi-layer approach works best: a canvas inner liner, a reflective foil vapor barrier, and a thick core of acoustic/thermal wool or poly-fiber.
Data Insight: The 2023 Cold Climate Housing Research Center notes that uninsulated floors account for 15% of heat loss in raised structures.
Industry Data
| Insulation Type | R-Value (approx) | Cost per sqm |
|---|---|---|
| Foil Bubble | R-3 | $15 |
| Cotton/Wool Layer | R-12 | $45 |
Common Mistakes
- Insulating without a vapor barrier (causes mold)
- Blocking the top vent
- Forgetting to insulate the floor deck
Frequently Asked Questions
- Can I use spray foam?
- It's possible but ruins the cover and makes it a permanent structure.
- How cold can it get?
- With proper insulation and a stove, domes remain comfortable at -30°C.
