Bottom line: Thermal insulated curtains reduce heat transfer in both directions — keeping warmth inside during winter and reflecting solar heat away during summer — while also improving blackout, sound damping, and energy efficiency. Dairui Curtain manufactures them for wholesale and private-label buyers in single- or double-layer constructions, with custom sizes, blackout and magnetic-mounting options, and full OEM/ODM packaging.
Why Choose Thermal Insulated Curtains?
Thermal insulated curtains are designed to reduce heat loss and improve indoor comfort. By adding extra layers of fabric or padding, these curtains block cold air from entering the room and keep warm air inside. For buyers in colder climates or markets with strong seasonal demand, this type of curtain is a practical and cost-effective solution.
Compared with regular curtains, thermal insulated curtains not only keep rooms warmer in winter but also reflect solar heat in summer, reducing air-conditioning load. They cut energy bills year round and are widely used in homes, hotels, offices, and commercial projects where both function and style are important.
Single-Layer Design with Polypropylene Padding


The most common design is the single-layer thermal curtain. It is made with polypropylene fiber padding, usually around 80gsm, placed between fabrics such as brushed polyester or taffeta. This structure creates a strong barrier against cold drafts while keeping the curtain lightweight and easy to install.
Single-layer insulated curtains are often chosen for homes and apartments where buyers want a simple, affordable way to improve comfort. They can block cold air effectively and also add some sound absorption.
Double-Layer Detachable Curtains


For stronger performance, there is the double-layer design. This style uses the single-layer insulated curtain as an inner layer and combines it with an outer fabric such as faux linen, plain weave polyester, or other materials. The two layers are connected with snap buttons, which allows buyers to detach or combine them as needed.
This detachable feature is useful in markets with changing climates. In colder months, the double-layer version provides maximum insulation. During warmer seasons, the outer layer can be removed, leaving the lighter single-layer curtain in place. This flexibility makes double-layer insulated curtains attractive for wholesale buyers who want to offer year-round solutions.
Fabric Choices and Heading Styles


Thermal insulated curtains can be produced with different surface fabrics to match interior styles. Common options include brushed fabric, polyester taffeta, faux linen, or plain weave polyester — see our guide to sourcing curtain fabric from China for details. Each fabric has its own texture and appearance, allowing buyers to select according to their target market.
Heading styles can also be customized. Options include grommets, rod pockets, Velcro tops, hooks, or tab tops. This ensures that the curtains can fit a wide range of installation needs, from residential use to hotel projects.
Summer Heat Reflection and Year-Round Performance
It is a common misconception that thermal curtains are only for winter. The same insulating structure that traps warmth in cold months also slows solar heat gain in summer, so rooms stay cooler and cooling costs drop. For hot or sunny markets, we can add a high-reflectivity backing or pair the thermal layer with a blackout curtain to maximize heat and light rejection.
This year-round performance — warmth retention in winter, heat reflection in summer — is a strong selling point for retailers and project buyers who want one product that works across seasons and climates.
Combining Blackout, Magnetic Mounting, and Custom Features
Thermal insulation is rarely bought on its own. Most wholesale and private-label buyers combine it with other functions to create a premium, market-ready product. Options include:
- Full blackout: a blackout mid-layer for complete light control alongside insulation.
- Magnetic mounting: a magnetic mounting system with magnets sewn into the curtain for tool-free installation.
- Custom sizes and weight: any width, length, and panel weight to specification — see our curtain width guide.
- Sound damping: denser constructions and linings that also reduce noise.
- Private-label packaging: custom branded, retail-ready packaging with barcode and size labels.

Frequently Asked Questions
Do thermal insulated curtains help in summer, or only in winter?
Both. Insulated curtains slow heat transfer in either direction. In winter they keep warm air inside; in summer a dense or reflective thermal layer blocks solar heat from entering, helping rooms stay cooler and reducing air-conditioning load. For summer-focused markets, a high-reflectivity backing can be added.
What materials and fabric specifications are available?
Single-layer designs use around 80gsm polypropylene fiber padding between fabrics such as brushed polyester or taffeta. Double-layer designs add an outer fabric like faux linen or plain-weave polyester. Surface fabric, GSM, and coatings (including blackout or reflective layers) can all be specified per order.
What is the minimum order quantity (MOQ)?
For custom production the MOQ is typically from 200 pieces per design and color. Sample and trial quantities are available separately. The exact MOQ depends on the fabric and construction you choose.
Are samples available, and how is pricing determined?
Yes. Swatch books and pre-production samples are available, though freight and proofing costs may apply. Unit price depends on fabric, size, construction, and volume, so larger runs such as 300, 500, or 1,000 pieces receive better per-unit pricing. Contact us for a quotation.
What is the production lead time?
Bulk production usually takes about 25 to 45 days after sample approval, depending on order size and fabric choice.
Can thermal curtains combine features like blackout, magnetic mounting, or custom sizes?
Yes. Thermal insulation can be combined with full blackout, custom panel sizes and weight, and a range of mounting styles including grommet, rod pocket, hooks, tab top, or a magnetic mounting system with magnets sewn into the curtain.
Do you offer OEM, private label, and custom branded packaging?
Yes. We provide OEM and ODM production based on your designs or ours, plus custom branded, retail-ready packaging folded with an insert and barcode and size labels for your market.
Can you ship to Europe and other markets?
Yes. We regularly export to Europe and worldwide by sea or air, and we will advise the best shipping option and Incoterms for your destination and order volume.
