Blauberg SonoFlex Thermally & Acoustically Insulated Flexible Ducting 125mm x 10m

Product Overview

The Blauberg SonoFlex Insulated Flexible Ducting is engineered to deliver superior thermal insulation, condensation prevention, noise reduction and flexibility. Designed for residential, commercial and industrial HVAC installations, it ensures long-lasting performance while complying with UK Building Regulations. Available in multiple diameters and lengths, SonoFlex is the professional choice for efficient ventilation solutions.

Condensation Control

Bathrooms, en-suites, kitchens and wet rooms are highly prone to condensation, leading to damp, mould and poor indoor air quality. SonoFlex ducting, with enhanced insulation in 100mm, 125mm and 150mm sizes, effectively reduces condensation risk by stabilising air temperature and limiting moisture build-up. This is particularly vital when ducting passes through unheated lofts or roof spaces in the UK’s cool, damp climate.

Condensation Risk Comparison

Dia / Length (mm / m) Start Temp (°C) End Temp (°C) Relative Humidity (%) Dew Point (°C) Airflow (L/s) Air Velocity (m/s) Risk Risk with SonoFlex
100 / 1.5 21.0 15.0 80 17.4 15 1.91 High Low
125 / 1.5 21.0 15.0 80 17.4 25 2.04 High Low

Temperature Regulation

Featuring 25mm Rockwool insulation with a thermal conductivity of ?0.04 W/mK, SonoFlex helps HVAC systems maintain stable air temperatures, reducing heat loss in winter and cooling loss in summer. This improves overall energy efficiency and comfort in line with UK regulations.

Temperature Deviation Performance

Duct Size (mm) Room Temp (°C) Winter (10°C Ambient) Summer (30°C Ambient)
100 21.0 -0.8 -0.3
125 21.0 -0.9 -0.4
150 21.0 -1.0 -0.5

250 21.0 -0.6 -0.2
315 21.0 -0.7 -0.3

Disclaimer: Values are theoretical estimates based on thermal conductivity ?0.04 W/mK.

Noise Reduction

The natural acoustic properties of Rockwool insulation within SonoFlex effectively absorb sound vibrations, significantly reducing ventilation system noise. This makes it ideal for noise-sensitive environments such as bedrooms, offices, and commercial premises.

Noise Reduction Performance

Dia / Length (mm / m) Velocity (m/s) Initial Noise (dBA) After Duct (dBA) Reduction (dBA)

Does not have everything shown
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
This kit does not have all the items shown. There are only 4 bags, not 6 as shown. There is only 1 red and 1 black roller, not 2 as shown. There is a screwdriver included but no directions. There is no odor to it and the items look durable but I have no idea how to replace the rollers and spinny things since there are no instructions. The bags fit my robot vacuum ok and are durable. There needs to be directions included as well as everything shown. Otherwise, you aren't getting your money's worth.

Solid Kit That Saves You Some Money
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I ordered this accessories kit for my Roborock Saros 10R mostly because I didn’t feel like spending a ton just to keep up with teh normal maintenance. After using it for a bit, I can say it’s been doing exactly what I hoped it would. First thing you notice is the cost of course, keeping these robot vacuums running can add up fast, and this kit really helps take the sting out of replacing the usual wear parts. Most of the pieces line up with the Saros 10R really well. Everything went in without a fight and once installed, it all works the way it should. Brushes rotate fine, filters sit where they’re supposed to, and nothing feels janky or poorly sized. Quality wise, it’s pretty close to the name brand stuff. You can tell there’s a small difference if you really look for it on some parts. Some of the plastic feels a bit lighter and a couple items don’t have that same premium feel. But in use, I’m not seeing much of a difference, cleaning performance is still strong and the vacuum hasn’t skipped a beat. Durability is the one thing you can’t fully judge right away. So far though, everything seems to be holding up nicely. No fraying, cracking, or early wear, so I’m cautiously optimistic they’ll last about as long as the originls. Overall, this kit is a good deal for the money. It does what it’s suposed to, saves you some cash, and keeps the Saros 10R running smoothly. Not perfect, but definitely worth it. Four stars.

most can fit saros 10, but not all
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I should have done a little more research with these. I purchased this for a Saros 10, i thought the Saros 10 and 10R was basically the same besides the filters. I was wrong. Although the brushes are the same size, they didnt fit. They lacked a special metal piece on one side, and the 10R has a different shape on the other, cant even jerry rig it to fit. The filters didnt fit my Saros 10, but that didnt cause the dropped rating, but they quality of it looks very good, and seems well made. The side brushes are good and they fit my Saros 10, replaced them and didnt have a problem. The bags also fit and they are very good. The mopping brushes did not fit, but it was very well made and definitely wasnt just a cheap set. The brush and screw driver were just to add additional number counts and basically useless.

Get the OEM mop cloths
Size: normal
When buying accessories for my eufy robot vac, I originally got my hands on some dupe accessories because they were cheaper. However- the mop cloths did not work well. The cheap construction of the dupes caused threads to constantly come out and get tangled, causing the robot to error out. I got these OEM ones and they work MUCH better. In this case it's best to buy the OEM parts even though they are more expensive!
