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
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

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
