Complete Shelter and Insulation: From Emergency Cover to Permanent Home
Shelter is the second survival priority after water. This campaign covers emergency shelters, permanent construction, insulation, heating, and the building science that keeps occupants comfortable.
Chapter 1: Emergency Shelters
| Shelter | Build Time | Capacity | Materials | Temperature | Difficulty |
|---|---|---|---|---|---|
| Debris hut | 1-3 hours | 1 person | Sticks, leaves, debris | +20°F above ambient | Low |
| Lean-to | 30-60 min | 1-2 people | Poles, branches, tarp/bark | +10°F above ambient | Very low |
| Snow cave | 2-4 hours | 1-3 people | Packed snow | Stable 32°F inside | Moderate |
| Quinzhee | 3-5 hours | 2-4 people | Piled snow (settled) | Stable 32°F inside | Moderate |
| Tarp shelter | 10-30 min | 1-4 people | Tarp + cordage + poles | Wind/rain protection | Very low |
| Wickiup | 2-4 hours | 2-4 people | Poles + brush/bark | +15°F above ambient | Low |
Debris hut (most effective primitive shelter): 1) Find or place ridgepole (8-10 ft long, one end elevated 3 ft). 2) Lean sticks against ridgepole (both sides, close together — ribs). 3) Pile small branches across ribs (lattice — holds debris). 4) Pile leaves/debris 3-4 feet thick over entire structure. 5) More debris = more insulation (you cannot add too much). 6) Stuff interior with dry leaves (insulation below you is critical). 7) Block entrance with debris plug. 8) Result: warm enough to survive freezing temperatures with no fire.
Chapter 2: Permanent Construction Methods
| Method | Materials | Skill Level | Time (small house) | Insulation | Lifespan |
|---|---|---|---|---|---|
| Log cabin | Logs, chinking | Moderate | 2-4 months | Good (thick walls) | 50-200 years |
| Timber frame | Heavy timbers, joinery | High | 3-6 months | Requires infill | Centuries |
| Cob (earth) | Clay, sand, straw | Low | 3-6 months | Good (thick walls) | Centuries |
| Adobe brick | Clay, sand, straw, sun | Low | 2-4 months | Excellent (thermal mass) | Centuries |
| Rammed earth | Subsoil, forms | Moderate | 2-4 months | Excellent (thermal mass) | Centuries |
| Stone | Local stone, mortar | High | 6-12 months | Good (thick walls) | Millennia |
| Straw bale | Straw bales, plaster | Low-moderate | 1-3 months | Excellent (R-30+) | 50-100+ years |
| Wattle and daub | Saplings, clay/mud | Low | 1-2 months | Moderate | 20-50 years |
| Sod | Grass sod blocks | Low | 1-2 months | Excellent | 20-50 years |
Log cabin construction: 1) Select straight logs (8-12 inch diameter, similar size). 2) Peel bark (prevents rot and insects). 3) Notch corners (saddle notch simplest: scoop half-round on bottom of log to sit on log below). 4) Stack walls, alternating direction. 5) Chink gaps (moss, clay, mortar between logs). 6) Door/window openings: cut after walls up, frame with dimensional lumber. 7) Roof: ridge pole + rafters + sheathing + shingles. 8) Foundation: stone piers or continuous stone wall (keep logs off ground). 9) Let settle 6-12 months before finishing interior (logs shrink).
Chapter 3: Insulation Materials
| Material | R-Value per Inch | Availability | Fire Risk | Moisture Risk | Cost |
|---|---|---|---|---|---|
| Straw bales | R-1.5-2.0 | Agricultural | Moderate (plastered = low) | Must stay dry | Very low |
| Wool (sheep) | R-3.5-4.0 | Animal husbandry | Low (self-extinguishing) | Absorbs/releases well | Moderate |
| Cellulose (paper/cotton) | R-3.2-3.8 | Recycled materials | Moderate (treat with borax) | Moderate | Low |
| Sawdust | R-2.0-2.5 | Sawmill waste | High (untreated) | Must stay dry | Very low |
| Cattail fluff | R-3.0-3.5 | Wetlands (wild) | High | Must stay dry | Free |
| Moss (dried) | R-2.0-3.0 | Forests (wild) | Moderate | Absorbs moisture | Free |
| Earth/clay | R-0.2-0.3 | Everywhere | None | Low | Free |
| Air gap (sealed) | R-1.0 per inch | Construction detail | None | Condensation risk | Free |
| Cork | R-3.5-4.0 | Cork oak trees | Low | Good resistance | High |
Straw bale wall: 1) Build foundation (raised, waterproof — bales must never touch ground). 2) Stack bales like bricks (running bond — offset joints). 3) Pin bales together (rebar or wooden stakes through bales). 4) Compress with top plate (ratchet straps or weighted plate). 5) Trim surface with hedge trimmer or chainsaw (flat for plastering). 6) Apply three coats plaster (lime or earth plaster — both sides). 7) Result: R-30 wall (better than most conventional construction). 8) Plaster protects from fire and moisture — unplastered bales are vulnerable.
Chapter 4: Heating Systems
| System | Fuel | Efficiency | Heat Output | Complexity | Best For |
|---|---|---|---|---|---|
| Open fireplace | Wood | 10-15% | Low (most heat up chimney) | Low | Ambiance, cooking |
| Enclosed stove (box) | Wood | 40-60% | Moderate | Low-moderate | Room heating |
| Rocket mass heater | Wood (small sticks) | 80-90% | High (stored in mass) | Moderate | Efficient whole-house |
| Masonry heater (Russian) | Wood (one firing/day) | 80-90% | High (stored in mass) | High | Cold climate, whole-house |
| Kang/ondol (heated floor) | Wood, crop waste | 60-80% | Moderate (radiant floor) | Moderate | Sleeping areas |
| Hypocaust (Roman) | Wood | 50-70% | Moderate (radiant floor) | High | Whole-house radiant |
| Passive solar | Sunlight | 100% (free) | Variable (climate dependent) | Low (design) | Supplemental heating |
Rocket mass heater: 1) Feed tube: insulated vertical tube where small sticks burn. 2) Burn tunnel: horizontal, insulated — fire burns sideways into riser. 3) Heat riser: tall, insulated vertical tube (creates powerful draft). 4) Barrel: inverted over heat riser (captures heat, radiates into room). 5) Exhaust: from barrel through thermal mass (cob bench, under-floor channels). 6) Chimney: short, at end of thermal mass run. 7) Burns small-diameter wood (sticks, prunings). 8) Virtually no smoke (complete combustion). 9) Thermal mass stores heat for 12-24 hours after 2-3 hour firing.
Chapter 5: Roofing
| Material | Lifespan | Slope Required | Weight | Difficulty | Fire Resistance |
|---|---|---|---|---|---|
| Thatch (straw/reed) | 15-40 years | Steep (45°+) | Light | Moderate | Poor |
| Wood shingles | 20-40 years | Moderate (30°+) | Light | Moderate | Poor |
| Slate | 75-200 years | Moderate (25°+) | Very heavy | High | Excellent |
| Clay tile | 50-100 years | Moderate (30°+) | Heavy | Moderate | Excellent |
| Metal (tin/steel) | 40-70 years | Low (15°+) | Light | Moderate | Excellent |
| Sod/living roof | 20-40 years | Low-moderate | Very heavy | Low | Good (when wet) |
| Bark | 5-15 years | Moderate (30°+) | Light | Low | Poor |
Reference Card
- Insulation below you matters most (ground steals heat fastest — insulate sleeping surface first). 2. Debris hut saves lives (3 hours of work = survival in freezing temperatures without fire). 3. Thermal mass stores heat (thick earth/stone walls absorb heat by day, release at night — free climate control). 4. Rocket mass heaters are revolutionary (80-90% efficient, burns sticks, stores heat in mass — best wood heating). 5. Keep wood off ground (moisture from soil rots wood — always elevate on stone or concrete). 6. Steep roofs shed water (the steeper the roof, the faster water runs off — critical for thatch and shingles). 7. Ventilate or rot (moisture from breathing and cooking must escape — always provide ventilation). 8. South-facing windows are free heat (in northern hemisphere, south windows gain more heat than they lose — passive solar).
