Blauberg SonoFlex Thermally & Acoustically Insulated Flexible Ducting 125mm x 5m

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

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

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

Excellent mineral sunscreen with minimal white cast.
Style: SPF 50
This is one of the healthier sunscreens I’ve found so far. You’re not likely going to find a mineral sunscreen that doesn’t leave some white cast. However, this one rubs in pretty good with minimal cast. You can dab on and rub in fairly easily… as long as you don’t use too much the white cast should be minimal. I am not sure how well this would work on darker skin tones. My arms are a medium skin tone… my legs are more of a light-medium tone. I prefer mineral sunscreens, and this is the best one I found so far and compatible to Supergoop mineral play. If you liked that one, you would likely enjoy this Coola one too.

Would not recommend
Style: SPF 50
I literally never write reviews but felt compelled to write one for this sunscreen because I was very caught off guard by all the positive reviews. This sunscreen leaves the most insane white sheen that never soaks in and gets on EVERYTHING. I put this on and drove to the beach and had sunscreen on my car seat, the steering wheel, the center console, the door, EVERYWHERE! It took forever to clean up and was such a hassle and that was after having let the sunscreen soak into my skin for an hour. Also the sunscreen is really thick and difficult to spread and makes you look ghostly white. Plus, the sunscreen has a really odd odor that reminded me of play dough? That might not be a negative thing for everyone but I found it unpleasant. There are definitely better mineral sunscreens out there. For the price I expected a much better product.

Sticky and white
Style: SPF 50
The sunscreen has a very sticky and thick texture. It will keep you from getting sunburnt, but it will also leave you with a white color.

Good sunscreen
Style: SPF 50
Super good coverage and it lasts a long time in the sun and even through water activities. The only negative is the white cast. Not as bad as others but just be aware it doesn’t fully rub in.

Great sunscreen & works for kids - even used in resorts!
Style: SPF 50
Terrific! I don’t feel it is as good as chemical ones but my favorite non-chemical one. Used on a long vacation and it did the job! Also didn’t cause pimples like other thick versions of this.
