Raising chickens can be a rewarding experience. However, ensuring your flock stays warm and comfortable through cold winter months requires proper planning and preparation.
This is especially important if your coop sits on a concrete slab or floor, a topic further discussed in our article on advantages of concrete chicken coops.
Concrete conducts temperature, rapidly losing heat in winter and gaining heat in summer. Chickens accustomed to roosting on the ground can find concrete floors uncomfortably cold.
Proper insulation, such as those discussed in our best insulation for chicken coops guide, helps maintain stable, livable temperatures within the coop.

Why Insulate a Chicken Coop on Concrete?
There are several reasons why insulation is important for a chicken coop on concrete:
-
Regulate temperature. Insulation prevents fluctuations in temperature to keep the coop a comfortable environment for chickens. It prevents chickens from getting too cold in winter.
-
Reduce stress. Stable temperatures keep chickens comfortable and reduce stress that can lower egg production.
-
Prevent illness. Insulation helps prevent temperature swings that can leave chickens vulnerable to respiratory illnesses.
-
Reduce mortality. Providing adequate warmth reduces risk of frostbite and hypothermia, especially important for combs, wattles, toes and feet.
- Lower costs. Insulating the coop reduces the amount of energy required to heat the coop in winter.
Comparison of Insulation Types for Chicken Coops
| Insulation Type | Advantages | Disadvantages |
|---|---|---|
| Rigid Foam | High R-value, Resists moisture | Chickens can peck at exposed foam |
| Loose-Fill | Can be installed under floor | Settles over time |
| Reflective | Reflects heat back into coop | Low R-value on its own |
| Insulating Concrete Forms | Combines insulation and concrete | Not suitable for existing coops |
How to Insulate a Chicken Coop on Concrete
There are several effective options for insulating a chicken coop built on concrete:

- Lower costs. Insulating the coop reduces the amount of energy required to heat the coop in winter.
How to Insulate a Chicken Coop on Concrete
There are several effective options for insulating a chicken coop built on concrete:
Rigid Foam Insulation
Rigid foam insulation boards, such as polystyrene or polyisocyanurate, provide an effective thermal barrier.
Rigid foam comes in sheets ranging from 1โ2 to 2 inches thick.
- Cut boards to fit snugly against coop walls and ceilings from the interior. Use adhesive or nails to secure in place.
- Seams between boards should fit tightly without gaps. Seal edges with caulk or spray foam.
- Cover insulating boards with plywood or another protective material. Chickens will peck at exposed foam.
Rigid foam insulation provides excellent thermal resistance with an R-value around R-5 per inch. It resists moisture and wonโt degrade over time.
Loose-Fill Insulation
Loose-fill insulation, such as cellulose, fiberglass, or mineral wool, can provide insulation under the concrete floor.
- Choose an insulation rated safe for chickens. Avoid fibrous materials like fiberglass that can irritate airways if inhaled.
- Remove a section of flooring and dig out 4-6 inches beneath the slab.
- Fill cavity with loose-fill insulation. Replace and secure flooring.
Loose-fill insulation settles over time so itโs important to install thickly. An R-value of at least R-15 is recommended.
Reflective Insulation
Reflective insulation contains sheets of aluminum foil that reflect heat back into the coop. It can be installed beneath roofing or around walls.
- Install according to manufacturer recommendations, leaving airspace between insulation and roof or walls.
- Seal seams with metal tape to prevent moisture damage.
Reflective insulation is often used with other insulating materials to enhance efficiency. It has a low R-value on its own.
Insulating Concrete Forms
Insulating concrete forms (ICFs) integrate insulation and concrete into one building system.
- Hollow foam blocks stack together like Lego bricks to form a hollow wall for pouring concrete.
- Once concrete cures, the foam blocks remain in place as thermal insulation.
ICF construction provides excellent insulation for new coop builds. Existing coops require other insulating strategies.
Important Considerations When Insulating a Coop on Concrete
To properly insulate your coop, keep the following considerations in mind:
-
Prevent moisture buildup โ Trapped moisture can lead to condensation and mold. Ensure insulation allows vapor to escape.
-
Prioritize roof insulation โ The majority of heat loss happens through the roof. Maximize insulation levels above chickens.
-
Allow for ventilation โ Ventilation removes moisture and ammonia. Donโt block vents when insulating walls.
-
Use proper R-values for your climate โ The colder your winters, the higher the R-value your insulation should have.
-
Install securely โ Insulation should be tightly sealed in place so chickens canโt pick or scratch it out of place.
- Check condition regularly โ Inspect insulation for damage. Patch or replace if chickens start pecking.
Additional Tips for Insulating a Chicken Coop on Concrete
Here are some extra tips and strategies for effectively insulating your coop:
- Install insulation underneath shavings or loose litter to prevent chickens scratching it up.
- In addition to insulation, seal all cracks, gaps and openings that allow drafts. Use caulk, spray foam or weather stripping.
- Double pane windows with low-emissivity coatings provide more insulation than single pane.
- Hang thermal curtains or rigid insulation sheets over windows at night, removing during day.
- Paint concrete walls white to maximize reflection and absorb less daytime warmth.
- Provide deep litter bedding chickens can burrow into for warmth and insulation.
- Add extra insulation along north facing walls which bear the brunt of winter winds.
- Ensure insulation rating is appropriate for application (wall, ceiling, etc).
Properly insulating your coop helps backyard chickens stay comfortable, productive and healthy through the winter.
