How moisture moves through buildings?

Understanding moisture transfer mechanisms can feel abstract when described in text. The following animation brings these processes to life, showing how vapour, air movement, liquid water, and heat interact within real building situations.

Rather than introducing new concepts, this animation reinforces what you have just learned in the previous section. It illustrates how multiple mechanisms often operate simultaneously, and how moisture pathways can overlap within the same building element.

Seeing these interactions visually helps explain why damp problems can be difficult to diagnose and why surface symptoms do not always reflect the true source.

As you watch, consider:

• Which mechanism seems most dominant in the examples shown?
• How might multiple pathways interact in a single damp problem?
• How could this understanding improve inspection or repair decisions in your context?

A short reflection is enough.
