Preventing Condensation with SonoFlex-150-5 Ducting

Managing condensation in your ventilation system is crucial, especially in high-humidity areas such as bathrooms, kitchens, and utility rooms. The Blauberg SonoFlex-150-5 is specifically engineered to tackle this issue effectively. Its robust 25mm Rockwool insulation minimises the risk of condensation by maintaining stable internal duct temperatures, thus preventing moisture from accumulating on duct surfaces.

Using the 150mm diameter SonoFlex-150-5 ducting in your HVAC system ensures that moisture is effectively managed, protecting your home or business from the harmful effects of dampness, such as mould growth and structural damage. This ducting is particularly beneficial in areas where the ventilation system passes through unheated spaces like lofts or crawl spaces, where temperature variations can otherwise lead to significant condensation issues.

Condensation Risk Table

Below is a table that compares the risk of condensation forming inside different ventilation ducts. The data highlights how using SonoFlex-150-5 significantly reduces these risks, especially under challenging conditions.

To ensure accuracy and regulatory compliance, the table is based on a duct length of 1.5 metres.

Given the varying British weather conditions, where damp and cool environments are common, the use of insulated ducting like SonoFlex-150-5 is essential for effectively managing condensation risks, particularly in moisture-prone areas.

Maintaining Temperature with SonoFlex-150-5 Insulated Ducting

The Blauberg SonoFlex-150-5 is designed with high-quality Rockwool insulation, known for its superior thermal properties and fire resistance. With a thermal conductivity of ≤0.04 W/mK, this ducting ensures that your HVAC system maintains consistent temperatures, reducing energy loss and enhancing overall efficiency. This is particularly crucial in climates like the UK, where maintaining stable indoor temperatures can significantly impact energy consumption.

By using the SonoFlex-150-5, you ensure that your ventilation system operates at peak performance, minimising heat loss or gain as air travels through the ducts. This results in a more comfortable and energy-efficient indoor environment, whether during the cold winter months or the warmer summer season.

Temperature Retention Table

This table shows the effectiveness of the SonoFlex-150-5 in retaining heat. It demonstrates how well the ducting maintains a steady room temperature of 21°C over a 1.5-metre length, under different seasonal conditions.

The negative values indicate the slight amount of heat lost in winter or coolness lost in summer, showcasing the ducting’s ability to minimise temperature fluctuations, which is key for energy savings and maintaining indoor comfort.

Noise Reduction Benefits of SonoFlex-150-5 Ducting

Beyond thermal performance and condensation control, the SonoFlex-150-5 also reduces noise levels within your HVAC system. The duct’s Rockwool insulation is naturally sound-absorbing, helping to prevent noise from traveling through the ductwork and into your living or working spaces. This makes the SonoFlex-150-5 an ideal choice for environments where quiet operation is a priority, such as in residential areas, offices, and healthcare facilities.

By integrating SonoFlex-150-5 into your ventilation system, you can significantly lower the noise generated by air movement and mechanical components, contributing to a more peaceful and comfortable indoor environment.

Noise Reduction Table

The following table highlights how effectively the SonoFlex-150-5 reduces noise as air passes through the duct. It compares noise levels before and after the air flows through the insulated duct, showcasing a significant reduction in decibels, making it suitable for noise-sensitive applications.
