So roof blanket or vapour permeable membrane – which one is better?

This is a conversation we come up against almost daily in our line of work, as homeowners and builders are often stuck between what’s easy and “normal” and what they suspect might be better.  They want to understand the difference between the standard roof blanket and a Vapour Permeable Membrane (VPM), also sometimes known as a Weather Resistive Barrier (WRB) depending on the product.  My answer is that there are pros and cons to both and I will list them here in an easy-to-read table.  The choice between the two is, of course, up to the individual homeowner and/or builder but it’s always better to make an informed choice instead of “doing what we’ve always done”.  Please read the below carefully and get in touch if you have questions!

Blanket insulation can cause roof leaks under flat metal roofs

If you’d like to order a waterproof, class 4 vapour permeable, non-flammable, non-perforated and highly durable vapour permeable membrane, such as Pro Clima’s Mento Plus, please get in touch!
