High/ low modules silicone

[Fallout]

Can anyone explain the difference? I believe high modules should be used in bathrooms?

Low is more stretchy.
High has less movement and will probably have anti mould in.

Low for widows
High for bathroom

Widows are more stretchy? I'll take your word for it.

Leaving aside the mould issue..
