6 Best Brooder Side Curtains For Temperature Regulation That Prevent Drafts
Maintain a stable brooder climate with the right side curtains. Our guide reviews 6 top options that prevent drafts and regulate temperature for chick health.
You’ve got your brooder set up, the heat lamp is dialed in, and the chicks are peeping away. But a sudden cold snap or a breezy day can turn that cozy environment into a death trap. A simple draft, that little stream of cool air sneaking in at floor level, is one of the biggest threats to a new flock.

Why Draft Control is Crucial for Your Brooder
A draft isn’t just a minor inconvenience for chicks; it’s a direct threat to their survival. Young birds can’t regulate their own body temperature effectively for the first few weeks. A constant stream of cold air forces them to burn precious energy just to stay warm, energy that should be going toward growth and immune system development.
You’ll see the evidence immediately. Chicks will huddle tightly under the heat source, even if the ambient temperature seems fine. This huddling can lead to smothering, and the stress makes them highly susceptible to issues like pasty butt. The goal isn’t just to make the brooder hot, but to make the heat stable and accessible everywhere.
Drafts create cold spots that chicks will avoid, effectively shrinking the usable space of your brooder. By blocking those drafts with a good side curtain, you create a consistent microclimate. This allows the chicks to move around freely, finding the perfect temperature zone they need without being forced into a pile by a cold breeze.
Tuff-Guard Clear Vinyl for Maximum Visibility
Sometimes, the best tool is the one that lets you keep an eye on things. Clear vinyl sheeting, often sold in heavy-duty gauges for porches or greenhouses, is an excellent brooder curtain for this reason. It blocks wind completely while allowing you to monitor your chicks’ behavior without disturbing them.
The primary benefit is obvious: you can see everything. You can spot huddling, check for lethargic birds, and ensure food and water levels are good at a glance. It also lets in natural light, which helps regulate the chicks’ day/night cycles and can reduce pecking issues. This is particularly useful if your brooder is in a well-lit barn or near a window.
The tradeoff, however, is insulation. Clear vinyl offers almost no R-value, meaning it won’t hold heat in the way an insulated material will. In a very cold garage or barn, you may need a more powerful heat source to compensate. Be mindful of direct sunlight, which can turn a vinyl-wrapped brooder into an oven on a sunny afternoon.
IronHorse Insulated Tarps for Cold Climates
If you’re brooding in an unheated shed in March or a drafty barn, you need to bring out the heavy-duty solution. Insulated tarps, like those made from IronHorse fabric, are designed for extreme temperature control. They are essentially a sandwich of waterproof, durable outer layers with a layer of insulating fiber fill in the middle.
These tarps create a serious thermal barrier. They don’t just block drafts; they actively help retain the heat generated by your lamp, which can significantly reduce energy costs. They are tough, waterproof, and will last for years, making them a solid investment if you consistently brood in challenging conditions.
The major downside is a complete lack of visibility. Once the curtain is down, you have no idea what’s happening inside without opening it up and letting cold air rush in. For this reason, they are best used on the most exposed sides of a brooder, perhaps in combination with a clear panel on the side you approach most often. Their cost is also higher, but it pays for itself in chick health and heating efficiency in cold climates.
Grower’s Solution Roll-Up Curtain System
For those who plan on raising birds year after year, a dedicated roll-up curtain system is a fantastic upgrade. This is a more permanent installation, involving a track or cable system that allows you to raise and lower a large curtain with a simple hand crank. It turns draft management and ventilation into a precise science.
The key advantage here is adjustability. On a cold, windy night, you can keep it sealed tight. On a warm, sunny day, you can roll it up halfway to provide excellent ventilation without creating a floor-level draft. This level of control is unmatched by fixed panels or draped tarps, allowing you to react perfectly to changing weather conditions.
Of course, this is a more involved option. It requires a solid frame to mount to and comes with a higher upfront cost for the curtain material, crank, and hardware. It’s overkill for a dozen chicks in a stock tank, but for a larger, semi-permanent brooder in a hoop house or dedicated shed, it’s a game-changer for managing flock health.
Coroplast Panels: A Rigid, Reusable Option
Think of the material used for yard signs—that’s Coroplast. This corrugated plastic is a surprisingly effective and versatile option for brooder walls. It’s lightweight, completely waterproof, and rigid enough to stand on its own or be easily attached to a simple wood frame.
The biggest benefit is its reusability and ease of cleaning. Unlike fabric, you can simply spray Coroplast down with a hose and sanitizer, and it’s ready for the next batch. The internal air channels also provide a small amount of insulation, better than a simple tarp. You can cut it to any size with a utility knife, making it perfect for custom-built brooders.
This durable, all-metal utility knife features a retractable blade with three adjustable positions for precise cuts. It offers quick blade changes and includes 10 extra SK5 blades for long-lasting use on various materials.
The main consideration is that it’s a rigid panel, not a flexible curtain. You’ll need to seal the seams where panels meet to prevent drafts. It can also become brittle in freezing temperatures, so it’s best suited for brooders inside a shed or garage rather than fully exposed to the elements.
US Cargo Control Blankets: A Budget DIY Fix
Never underestimate the utility of a simple moving blanket. These thick, padded blankets sold by companies like US Cargo Control are an excellent, low-cost way to insulate a brooder. They are designed to be tough and have a decent insulating capacity thanks to their quilted construction.
This is a fantastic budget-friendly choice. You can often find them for a few dollars apiece, and they are incredibly easy to work with. Just drape them over the sides of your brooder (ensuring they are a safe distance from the heat lamp!) and secure them with clamps or staples. They do a great job of blocking drafts and holding in a surprising amount of warmth.
However, they are not a perfect solution. Their biggest drawback is that they are not waterproof and will absorb moisture, which can lead to mold and a chilled environment. They also collect dust and dander, making them harder to clean than a non-porous surface. Think of them as a great temporary or emergency fix, especially for brooders located in dry, protected areas.
Upcycled Feed Bags: The Ultimate Frugal Choice
For the truly resourceful farmer, the solution is right in your feed shed. Woven polypropylene feed bags are tough, water-resistant, and, best of all, free. By carefully splitting them along the seams, you can stitch or even tape them together to create a surprisingly effective draft barrier.
The appeal is pure frugality. You are taking a waste product and turning it into a useful tool. A wall made of feed bags will stop wind dead in its tracks and hold up to the pecking and scratching of curious chicks. It’s a practical, no-cost way to solve a critical problem.
The tradeoffs are insulation and noise. These bags have zero R-value, so they only block drafts; they don’t hold heat. They can also be crinkly and loud, which might stress some chicks initially. But if the main problem is wind and your budget is zero, a feed bag curtain is infinitely better than nothing.
Safe Installation and Proper Ventilation Tips
Blocking drafts is only half the battle; doing it safely is what matters. Never allow any flammable curtain material like a moving blanket or tarp to come into direct contact with your heat lamp. Always maintain a safe, manufacturer-recommended clearance and secure your lamp with multiple redundant chains or wires. A fire in a brooder is a devastating and fast-moving disaster.
Secure your curtains firmly. Chicks are surprisingly strong and persistent. A loosely clamped tarp can be pulled down into the brooder, creating a smothering or fire hazard. Use wood battens, screws with washers, or heavy-duty clamps to ensure your curtain stays put.
Finally, remember the crucial difference between a draft and ventilation. A draft is unwanted horizontal air movement at chick level. Ventilation is the essential exchange of fresh air to remove ammonia and moisture. A brooder must breathe. Seal the bottom 12-18 inches to stop drafts, but ensure there is a way for stale, moist air to exit higher up. An airtight brooder is a recipe for respiratory illness.
The best brooder curtain isn’t the most expensive one; it’s the one that fits your specific climate, budget, and setup. Whether you choose clear vinyl for visibility or stitch together feed bags for frugality, the goal is the same: creating a stable, draft-free environment. Get that right, and you’re well on your way to raising a healthy, thriving flock.
