Thermal Blinds in Auckland

A cold bedroom behind single glazing is the room thermal blinds are made for. We measure every window in person and fit each blind close to the glass, because the fit is what keeps the warmth in.

Or call 09 441 9455. Mon to Fri, 8:00am to 4:30pm.

You heat the room all evening, and by morning the warmth has gone out through the glass. It's usually a bedroom, often the kids' one, and it's the same every winter.


A thermal blind slows that heat loss, and the closer it fits, the more warmth stays in the room. One of our two owners measures every job and tells you what each window needs.

Do thermal blinds keep a room warmer? Yes, and here's how


Yes, they do. A thermal roller blind has a backing on the fabric that slows heat passing through it. That's why you'll also hear them called thermal backed blinds or insulating blinds.


The blind also traps a layer of still air between the fabric and the cold glass, and that still air holds warmth in the room. It slows heat loss rather than stopping it.


The less that air can move, the better it works. So the fit matters as much as the fabric.


Thermal blinds on single glazed windows


Single glazed windows lose the most heat, so they gain the most from a thermal blind.


Blinds for single glazed windows are worth a look in:


✓ Bedrooms that never hold their warmth overnight

✓ Living rooms where the heat pump never seems to catch up

✓ Rentals, where a landlord or tenant wants a warmer room without a big job

✓ West-facing rooms that cook in summer


Thermal fabric is one of the options across our roller blinds range, so it sits comfortably alongside the blinds in the rest of the house.


Outside Auckland? We ship thermal roller blinds anywhere in NZ, though the free measure and install is for the Auckland area.


Thermal blinds in summer


The same blind keeps the sun's heat off the room on a hot afternoon, so a west-facing room stays usable.


Side guides, pelmets and a close fit keep the warmth in


A close fit is where the warmth is won. Four things help a blind sit tight to the window and finish it neatly:


✓ Side guides down each edge, so less cold air slips round the sides

✓ A pelmet across the top, closing the gap over the roll

✓ A face fit over the opening with a good overlap, where the window suits it

✓ An enclosed head box (valance) that hides the roll and cuts light at the top


Fabric edges are ultrasonically sealed, so they stay neat against side guides. At the measure we'll tell you which of these will make a real difference on each window, and which won't.


Thermal blinds or curtains for insulation?


We supply both, so you'll get a straight answer.


Roman, one of our two owners, is clear on this: floor-to-ceiling blockout curtains with a thermal lining are usually warmer, because they cover more and trap more air. If a bedroom is cold and the window suits fabric, he'll point you to our thermal curtains and drapes.


Thermal roller blinds suit windows where curtain fabric won't work, and rooms where you want a cleaner line. Some rooms end up with both, and we decide that at the measure, window by window.


Also blockout: dark as well as warm


Most thermal fabrics are also blockout, so thermal blockout blinds give you a dark room as well as a warmer one. That suits a bedroom that wakes you at dawn or catches a street light.


Standard blockout still leaks a border of light at the edges. For a truly dark room we add the CF90 pelmet and side guides system. There's more on that on our blockout blinds page.


Want daytime light too? Dual roller blinds pair two fabrics on one double bracket, such as a sunscreen for the day and a blockout for the night.


Why we measure every window in person


How well the blind works depends on the fit, so one of our two owners, David or Roman, measures every job. Roman leads every install with our own team, and most of our customers are repeat or referred.


We bring the showroom to you. Samples go up against your own windows and joinery, because what looks right in a showroom often doesn't at home.


We'll also go through chain, spring-assist or motorised operation, with a chain tidy for child safety. Your quote comes from that visit, which is why we don't give prices from window sizes.


Book the measure: call 09 441 9455.


How long do thermal blinds take?


They take 3 to 4 weeks from deposit to install, and longer before Christmas. If you want them up for the first cold nights, book the measure early.

What our customers say about their blinds


Most of our customers are repeat or referred, and we have more than 260 five-star Google reviews. Peter's review is the summer side of the story: keeping the afternoon heat out.


"The blind was installed in good time ... it has certainly made a difference in protecting my apartment from the hot afternoon sun and it has opened up the space I can use with my balcony." (Peter, March 2022)

"From my initial contact, David & Roman have been fabulous communicators & clearly know their products, I never felt pressured ... The end result for the insect screens & roller blinds is just lovely." (Rachel, June 2026)

"We had some blinds put up in our house 5 years ago by Rollerflex and now we have replaced curtains with rollerflex blinds in the rest of the house.. Great service, great price and quality product that lasts." (Kimberley, September 2025)

Thermal blind questions


Do thermal blinds actually keep a room warmer?


Yes. The backing slows heat through the fabric and the blind traps still air against the glass, so the closer the fit, the more warmth stays in.


Are thermal blinds worth it on single glazed windows?


Yes. Single glazed windows lose the most heat, so they gain the most. A blind slows that heat loss rather than stopping it, and a close fit gets the most from it.


Thermal blinds or curtains for insulation?


Floor-to-ceiling blockout curtains with a thermal lining are usually warmer. A thermal blind suits windows where fabric won't work, and we supply both.


Are thermal blinds also blockout?


Most thermal fabrics are also blockout. Add side guides and a pelmet and the room gets darker as well as warmer.


Do thermal blinds help in summer?


Yes. The same blind keeps the sun's heat off the room.


How long do thermal blinds take?


3 to 4 weeks from deposit to install, and longer before Christmas.


Can you give me a price from my window sizes?


No. The fit is what makes the blind work, so we measure every window in person first. The measure and quote are free in the Auckland area.


What warranty do you give?


Two years full, parts and labour, with no call-out fee and no labour charge. The roller blind fabric is also backed by the manufacturer for 5 years. See our warranty page.
