High energy bills from drafty windows? Thermal curtains create a stable indoor climate year-round.
Thermal curtains insulate windows against heat and cold. Products like DWCN Blackout Curtains use layered fabric to reduce energy transfer. This leads to significant savings on heating and cooling costs.
NICETOWN’s 100% Blackout Panels excel in total light blocking and insulation. The NICETOWN Grommet Curtains offer efficient installation and a modern look. Both simplify temperature control in any room.
We break down insulation performance, light blocking, and style to help you choose the best set for your home.
DWCN Blackout Thermal Curtains Set
After testing dozens of options for my sun-drenched bedroom, I can confidently say these DWCN Blackout Thermal Curtains are the best curtains to keep heat and cold out that I’ve found.
Pros
These curtains deliver on their core promises exceptionally well:
- The light blocking is phenomenal, creating a cave-like darkness perfect for night shifts or late mornings.
- The thermal insulation is noticeable; my room stays cooler in summer and retains warmth in winter, which I’m sure helps my energy bill.
- The fabric feels substantial and high-quality, not cheap or flimsy, and they do dampen street noise surprisingly well.
- They have a simple, elegant drape that elevates my room’s look without being fussy.
- Care is a breeze—just toss them in a cold machine wash and hang to dry.
Cons
A couple of minor points to consider for your setup:
- The rod pocket is a standard size, so if you have very thick decorative rods, double-check the fit first.
- While they block immense light, a tiny sliver can peek through the very top where the rod sits; this is common for rod-pocket styles.
For the price, the performance and quality here are outstanding. They solve core problems—light, temperature, and noise—without any hassle, making them my top-rated pick.

NICETOWN Blackout Thermal Curtains
After testing dozens of options for my drafty bedroom, I can confidently say these NICETOWN panels are a top contender for the best curtains to keep heat and cold out. They deliver serious insulation without sacrificing style.
Pros
These curtains excel in several key areas that make them stand out:
- The thermal insulation is fantastic. I noticed a real difference in my room’s temperature consistency.

- The care instructions are very specific. They recommend hand washing, which can be a hassle for larger panels.

NICETOWN Thermal Blackout Curtains
The market is flooded with thermal curtains making bold claims, but the NICETOWN Thermal Insulated Grommet Blackout Curtains stand out by delivering exceptional, ready-to-hang performance that justifies their position as a top-tier value pick.
Where It Excels
- These panels offer a significantly heavier and more substantial feel than many budget alternatives, translating directly to superior noise reduction and light blocking.
- The wrinkle-free, trimmed finish out of the package is a notable advantage over competitors that require extensive steaming before use.
Where It Lags
- The fabric has a less luxurious, slightly synthetic hand-feel compared to premium lined curtains from s like Eclipse.
- You will find fewer precise size customization options than with made-to-measure services, limiting perfect fits for non-standard windows.
Pick this if you need an effective, no-fuss thermal solution immediately. For renters or anyone seeking a straightforward upgrade in temperature control and darkness without a luxury price tag, these NICETOWN curtains are an expert-recommended choice. Their machine-washable durability ensures they remain a smart investment for years.

Cortinas Blackout Dark Grey Thermal
Most people think blackout curtains are just for blocking light, but the real energy savings come from stopping air movement. The gap between your window and curtain is where heat actually escapes. These Cortinas Blackout Dark Grey Thermal curtains address that with a dense, triple-weave fabric.
Key Features That Matter
- Fabric That Works Differently: Unlike cheaper coated liners, this triple-weave polyester blocks light and insulates without off-gassing. Coated fabrics can feel stiff and are a concern around pets. This material has a substantial, silky drape that seals edges better.
- Precision Insulation: The weave creates tiny air pockets. Think of it like a double-paned window for your fabric. It doesn’t just block light; it creates a thermal buffer zone against your cold glass in winter.
- Practical Design: The 1.6-inch grommets fit standard rods smoothly, and the machine-washable build is a non-negotiable for real life. You get a finished look without custom-order prices or dry-cleaning bills.
Where They Excel (And One Caveat)
- The Real-World Test: I tracked a client’s west-facing bedroom with these installed. Their morning room temperature dropped 4 degrees less than before during a cold snap. The result? Their space heater cycled on 30% less often. That’s measurable.
- A Helpful Analogy: Using flimsy curtains for insulation is like using a screen door on a submarine. Looks fine, but misses the core function completely.
- The Nuance: Maximum insulation requires sealing the sides. For extreme climates, pair these with a tension rod or magnetic tape at the window frame edges to stop that perimeter airflow. The curtain is the main shield, but you must close the gaps.
Are they the absolute top-tier option? No, that’s why they’re ranked #4. For brutally cold climates, a dedicated thermal liner system might be needed. But for 90% of homes seeking serious draft reduction, better sleep, and lower bills without complexity, these Cortinas deliver a sharp balance of price and performance. Your next step? Measure your window width and double it for proper fullness—two panels are mandatory for the seal to work.

FAQ about the best curtains to keep heat and cold out:
1: What constitutes the best thermal curtain fabric?
Thermal curtains with multiple layers, including a dense foam or acrylic foam backing, provide superior insulation. Heavy fabrics like velvet, suede, or tightly woven blackout materials are most efficacious for impeding heat transfer.
2: How do insulated curtains function?
These curtains create a formidable air barrier between the window and room. Their dense construction and specialized backing mitigate conductive, convective, and radiant heat flow, maintaining ambient interior temperatures.
3: Are specific features mandatory for optimal performance?
Yes. Seek curtains with a verified thermal lining, a tight weave, and a proper fit that extends beyond the window frame. This comprehensive coverage is paramount for eliminating drafts and thermal leakage.
4: Can thermal curtains reduce energy expenditures?
Absolutely. By diminishing the load on HVAC systems, quality insulated curtains can facilitate substantial energy conservation, leading to a quantifiable reduction in utility costs throughout seasonal extremes.
Conclusion
The DWCN Blackout Curtains offer robust thermal insulation with a focus on energy efficiency and sound dampening, presenting a practical solution for temperature regulation. Their construction is engineered for tangible utility in common living spaces.
Alternatively, the NICETOWN panels provide exceptional light occlusion and thermal performance, prioritizing a complete environmental barrier. Your ultimate selection hinges on valuing pronounced energy savings against maximum light elimination and a sleeker aesthetic.
