Given the British climate, where cool and damp conditions are common, using insulated ducting like the SonoFlex-100-10 becomes crucial in effectively managing condensation risks, especially in moisture-prone areas like bathrooms and kitchens.

Using SonoFlex-100-10 Flexible Insulated Ducting to Regulate Temperature

The SonoFlex-100-10 Insulated Flexible Ducting features 25mm Rockwool insulation, known for its exceptional thermal performance and flame-retardant properties. With a thermal conductivity of ≤0.04 W/mK, it meets UK building regulations, making it an excellent choice for maintaining consistent air temperatures within your HVAC system.

This insulation effectively minimises heat loss or gain, which is especially important in the British climate, where temperature fluctuations can impact energy efficiency. Insulated flexible ducting like the SonoFlex-100-10 plays an important role in keeping your indoor environment stable and comfortable.
