What Are Innovative Alternatives to Traditional Coop Insulation?

When it comes to keeping your chickens warm and comfortable in their coop during cold weather, insulation is key. Traditional insulation materials like fiberglass batts get the job done, but they can be messy to install and may contain chemicals you want to avoid around your flock. 

Thankfully, there are a number of innovative, natural insulation solutions that work just as well, if not better. 

Here are some of the top options to consider:

Earthwool

• Made from recycled glass and sand, earthwool is a great sustainable choice.

• It has similar insulating properties as traditional fiberglass insulation.

• Earthwool is fire-resistant and repels moisture.

• It contains no formaldehyde or other harmful chemicals.

• Simple to install in walls, ceilings and floors. Comes in easy to handle rolls and batts.

• Can be blown into coop walls and ceilings. Conforms to all spaces and cracks.

• Settles well over time and won't sag or deteriorate.

• Excellent at damping noise and inhibiting airflow. Creates draft-free space.

• Is moisture resistant. Won't grow mold or mildew.

• Low cost and eligible for many energy efficiency rebates and tax credits.

Vermiculite

• Lightweight mineral made from heated mica. Expands when heated.

• Available in bags for pouring into walls or attic spaces.

• Works well for open block or stud wall cavities. Expands to fill small spaces.

• R-value of 2.7 per inch. Excellent heat insulator.

• Repels moisture while allowing walls to breathe. Won't rot or deteriorate over time.

• Non-combustible and fireproof up to over 2000°F.

• Low cost and easy DIY installation. No protective gear needed.

• Naturally mildew, rot and insect resistant. Deters rodents.

Pea Gravel

• Small, smooth stones made from river rock. Natural insulation.

• Excellent for filling floor cavities up to 12 inches deep.

• Stabilizes soil temperature and provides dry footing. Allows drainage.

• Retains heat from the earth and radiant heat from the coop.

• Provides thermal mass to reduce day/night temperature swings.

• Loose fill is easy to install. Levels and packs down well.

• Durable and extremely long lasting. Won't decompose or need replacing.

• Available locally from aggregate and landscape supply stores.

• Can be reused if coop is redesigned or expanded.

Straw

• Readily available agricultural byproduct from wheat, rice, barley, oats.

• Harvested straw has good insulation value with an R-value of R-1.4 per inch.

• Can be used as loose fill, bales, or straw boards.

• Bales can be stacked along exterior walls as insulation. Also helps weatherproof.

• Works well for stuffing into wall cavities, ceilings, and floors.

• Is easy to install in existing coops or new construction.

• An affordable and renewable insulation source. Often free or cheap.

• Discourages rodents from nesting when used properly.

• Provides good ventilation and air circulation.

Hemp

• Fast growing, renewable and sustainable crop used for fiber and oil.

• Can be processed into batts, loose fill, or rigid boards.

• Has R-value between R-3.5 to over R-5 per inch. Excellent insulator.

• Made from the inner hurd (core) of hemp stalks.

• Naturally moisture and mold resistant. Allows indoor humidity control.

• Hemp binds well with lime plaster for added insulation and breathability.

• No off-gassing or fumes. Safe for enclosed coops.

• Carbon negative to grow and process. Benefits air quality.

• Can be locally grown and processed in many areas.

Soybean Hulls

• Waste product from soybean processing for oil and food.

• Lightweight and highly porous. Works for cavity fill insulation.

• R-value of R-2 per inch. Best in thick fills of 12" or more.

• Contains no VOCs, formaldehyde, or toxins. Naturally safe.

• Readily available and inexpensive agricultural waste product.

• Good moisture resistance. Allows interior humidity control.

• Can be poured or blown into wall studs or attic rafters.

• Has a natural brown color. No dyes or artificial colors.

• Will decompose if exposed to moisture. Best sealed in cavities.

Wood Shavings

• Byproduct of milling lumber, wood shavings make economical insulation.

• Can be poured, baled, and pressed into rigid boards.

• R-value of R-2 to R-4 per inch depending on wood species and moisture.

• Usually easy to source locally from wood mills if not commercially sold.

• Offers good air circulation and indoor humidity regulation.

• If kept dry, won't decompose or compress over time. Long lasting.

• Seals small cavities thoroughly. Deters insects and rodents.

• Has a natural wood smell. Avoid treated or painted wood varieties.

• Can eventually decompose if exposed to moisture. Keep contained.

Coir

• Made from coconut fibers, the hairy layer between shell and fruit.

• Often used as a peat moss substitute. Renewable and plentiful.

• Can be formed into mats, batts, boards, bales, and loose fill.

• R-value of R-1.4 per inch. Great for stuffing small cavities.

• Excellent acoustic dampening and sound blocking abilities.

• Resists rot, mold, mildew, bacteria, and fungi. Long lasting.

• Sustainably harvested as an agricultural byproduct.

• Neutralizes odors. No synthetic scents or irritants.

• Absorbs water and allows interior humidity regulation.

Green Roofs

• Using soil and plants directly on the coop roof.

• Can reduce heat gain from sun exposure dramatically.

• Plants cool the air through respiration and evapotranspiration.

• Growing medium acts as insulation, absorbing and retaining heat.

• Reduces temperature swings throughout the day and night.

• Thick soil layer protects roof from hail, UV rays, and debris.

• Additional moisture barrier protects underlying roof.

• Can be simple shallow trays or intensive full gardens.

• Softens and mimics natural landscape. Blends into environment.

• Provides habitat for pollinators and beneficial wildlife.

Additional Considerations for Coop Insulation

When installing insulation in your chicken coop, there are a few other factors to consider beyond just thermal performance. Proper insulation plays an important role in fire safety, predator protection, and chicken health. Insulation can also impact winter egg production, chicken behavior, and climate control within the coop.

When upgrading insulation in older coops, consider a combination of thermal insulation for temperature control and acoustic insulation to dampen outside noises. 

The amount of insulation needed will depend on factors like your climate zone and coop size. Always inspect your coop's insulation frequently and replace any damaged, sagging, or degraded insulation right away. Proper installation and maintenance will ensure your chickens stay comfortable and productive all year long.
