With new buildings being made to be as energy efficient as possible, and the UK aiming for 95% of its electricity usage to be low carbon by 2030, it is imperative to understand how we can make the most of our ventilation. This is where MVHR units come in.

To prevent mould, fresh air should constantly be introduced into your dwelling daily, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or MVHR units. Almost all of this is facilitated by ducting.

Flexible ducting 101

Flexible ducting is a variation on ducting, as the name suggests, it is flexible, as opposed to the regular round ducting which is solid. Depending on the area of installation, flexible ducting can be better than regular ducting, and vice versa.

The flexible nature of flexible ducting allows it to be manipulated into spaces that can’t support regular ducting. This is ideal for smaller homes and spaces. Generally, any manipulation made to flexible ducting is planned before installation, and done during the installation.

Why would I require flexible ducting?

Flexible ducting is ideal for those with limited space but still require ducting. In some instances, it can also be used as a temporary solution. You shouldn’t have to compromise between the space in your home and the ventilation it requires, this is why flexible ducting can be so helpful. An example of flexible ducting can be seen with vented tumble dryers.
