Blauberg SonoFlex-200-5 Insulated Flexible Ducting

The Blauberg SonoFlex-200-5 Insulated Flexible Ducting is designed to meet the demands of modern ventilation systems with a larger 200mm diameter and a convenient 5-metre length. This ducting provides outstanding thermal insulation, moisture control, and noise reduction, making it a versatile choice for both residential and commercial HVAC installations. With full compliance with UK building regulations, the SonoFlex-200-5 ensures that your ventilation system performs efficiently while maintaining durability and reliability over time.

Condensation Control with SonoFlex-200-5 Ducting

Condensation is a common issue in ventilation systems, particularly in environments with high humidity, such as bathrooms, kitchens, and utility areas. The Blauberg SonoFlex-200-5 is specifically designed to address this problem. Its robust 25mm Rockwool insulation works by maintaining consistent internal temperatures within the duct, significantly reducing the likelihood of condensation forming on the duct surfaces.

By using the 200mm diameter SonoFlex-200-5 ducting in your HVAC system, you can effectively manage moisture, protecting your property from the damaging effects of dampness, such as mould growth and structural deterioration. This ducting is especially beneficial in installations where the ductwork passes through unheated or cooler areas, such as lofts or basements, where temperature fluctuations could otherwise lead to condensation issues.

Condensation Risk Assessment Table

The table below provides a comparison of the risk of condensation forming inside ventilation ducts. It highlights how the SonoFlex-200-5 effectively minimises the risk, ensuring that your ventilation system remains free from moisture-related problems.

The data is based on a duct length of 1.5 metres to provide accurate information and ensure regulatory compliance.

Dia / Length (mm / m)	Starting Temp (°C)	End Temp (°C)	Relative Humidity (%)	Dew Point (°C)	Airflow (L/s)	Air Velocity (m/s)	Condensation Risk	Condensation Risk Using SonoFlex
200 / 1.5m	21.0	18.0	70	15.3	140	4.46	Medium	Low

Given the UK’s variable weather conditions, particularly its cool and damp climate, the use of insulated ducting like SonoFlex-200-5 is essential to effectively manage condensation risks in both residential and commercial settings.

Temperature Stability with SonoFlex-200-5 Insulated Ducting

The Blauberg SonoFlex-200-5 is equipped with 25mm Rockwool insulation, recognised for its excellent thermal properties and fire-resistant qualities. This ducting is designed to maintain consistent air temperatures within your HVAC system, minimising energy loss and improving overall efficiency. This is particularly beneficial in climates like the UK, where temperature stability is critical to energy conservation and maintaining a comfortable indoor environment.

By integrating the SonoFlex-200-5 into your ventilation system, you can ensure that heat loss or gain is kept to a minimum as air travels through the ducts. This results in a more energy-efficient system and a more stable indoor climate, regardless of external weather conditions.

Temperature Retention Table

The table below demonstrates the heat retention capabilities of the SonoFlex-200-5, showing how effectively it maintains a stable room temperature of 21°C over a 1.5-metre length under various seasonal conditions.

The negative values indicate the slight amount of heat lost in winter or coolness lost in summer, underscoring the ducting’s efficiency in maintaining consistent temperatures, which is crucial for energy savings and indoor comfort.

Duct Size (mm)	Room Temperature (°C)	In Winter (Ambient Temp: 10°C)	In Summer (Ambient Temp: 30°C)
200	21.0	-0.6	-0.2

Disclaimer: The thermal performance values provided are based on theoretical calculations using a thermal conductivity of ≤0.04 W/mK. Actual performance may vary depending on specific installation conditions, airflow, and environmental factors.

Noise Reduction with SonoFlex-200-5 Ducting

Beyond its thermal and moisture control capabilities, the SonoFlex-200-5 also excels in reducing noise levels within your HVAC system. The Rockwool insulation used in this ducting is naturally sound-absorbing, preventing noise from travelling through the ductwork and into occupied spaces. This makes the SonoFlex-200-5 an ideal choice for settings where noise control is important, such as homes, offices, and healthcare facilities.

By incorporating SonoFlex-200-5 into your ventilation system, you can significantly reduce the noise generated by air movement and mechanical equipment, contributing to a quieter and more comfortable indoor environment.

Noise Reduction Performance Table

The following table illustrates how effectively the SonoFlex-200-5 reduces noise as air travels through the duct. It compares noise levels before and after the air passes through the insulated duct, showcasing a substantial reduction in decibels, making it suitable for noise-sensitive environments.

Dia / Length (mm / m)	Air Velocity (m/s)	Initial Noise Level (dBA)	Noise Level After Duct (dBA)	Noise Reduction (dBA Drop)
200 / 1.5m	4.46	57	45	12

Disclaimer: The noise reduction values are based on theoretical conditions. Actual performance may vary depending on specific installation conditions and environmental factors.
