Thermal curtains for warmer, cosier rooms

Yes, when properly fitted. A well-fitted thermal curtain reduces heat loss through windows significantly, with some studies showing reductions of up to 60% depending on window type. The key is that the curtain fits without gaps. Your consultant will ensure this during installation.

They are the same thing. Thermal curtains and insulated curtains both refer to curtains with a lining or fabric construction designed to reduce heat transfer through windows. The two terms are used interchangeably.

Not exactly. Blockout curtains are designed primarily to block light, though the additional lining provides some insulation as a secondary benefit. Thermal curtains are designed primarily for insulation, though heavier fabrics will also reduce light. Your consultant will explain which option, or which combination, suits your room.

The difference depends on your window type and how well the curtain fits. Well-fitted thermal curtains can reduce heat loss through windows by as much as 60% compared to an uncurtained window. Your consultant will give you an honest assessment based on your specific rooms and windows.

Yes. Thermal curtains insulate in both directions. In summer, they reduce the transfer of heat from direct sunlight into the room, helping to keep spaces cooler without relying solely on air conditioning or fans.

A separate thermal lining, rather than a thermally coated fabric, generally performs better because it creates an additional air pocket between the fabric and the lining. Your consultant will explain the difference and show you both options during the visit.

For most NZ homes, particularly those with older single-glazed windows, large ranch sliders, or rooms that are difficult to heat, the energy savings over time make thermal curtains a worthwhile investment. Your consultant will give you an honest view for your specific home.

Yes. All Russells thermal curtains are custom-made to your exact measurements in our Nelson workroom, backed by our Guaranteed Perfect Fit.

Yes, thermal curtains can be fitted to doors as well as windows, including ranch sliders and French doors, where heat loss is often significant. Your consultant will advise on the right track and fitting approach for your specific door.

They’re one of the safest choices you can make. Curtains don’t need cords or chains to work, so there’s nothing dangling for little hands or curious paws. We’d steer you away from cord controls — and if you’d rather not draw them by hand (which can mark the fabric over time), a wand or automation keeps things easy and safe. Just ask and we’ll talk you through it.
