Blauberg SonoFlex Thermally & Acoustically Insulated Flexible Ducting 100mm x 10m
Blauberg SonoFlex Thermally & Acoustically Insulated Flexible Ducting 100mm 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 |
| 150 / 1.5 | 21.0 | 15.0 | 80 | 17.4 | 100 | 5.7 | High | Low |
| 200 / 1.5 | 21.0 | 18.0 | 70 | 15.3 | 140 | 4.46 | Medium | Low |
| 250 / 1.5 | 21.0 | 18.0 | 70 | 15.3 | 180 | 3.67 | Medium | Low |
| 315 / 1.5 | 21.0 | 18.0 | 70 | 15.3 | 220 | 2.82 | Medium | 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 |
| 200 | 21.0 | -0.6 | -0.2 |
| 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) |
|---|---|---|---|---|
| 100 / 1.5 | 1.91 | 50 | 40 | 10 |
| 125 / 1.5 | 2.04 | 52 | 42 | 10 |
| 150 / 1.5 | 5.7 | 55 | 43 | 12 |
| 200 / 1.5 | 4.46 | 57 | 45 | 12 |
| 250 / 1.5 | 3.67 | 59 | 46 | 13 |
| 315 / 1.5 | 2.82 | 61 | 47 | 14 |
Disclaimer: Noise values are theoretical. Actual results depend on installation.
