Intelligent Membranes

Our company ordered Passive Purple External and Brush and The Goat liquid applied roofing membrane from Intelligent Membranes and had it shipped across the pond without issues to Chicago.

Adam White (owner) Loz and the team are great to work with and very responsive despite the time difference. No issues with customs at O'Hare either.

The subs say passive purple products cover well and clean up is easy. The roofer that installed The Goat says its the only liquid applied roof membrane he will use.

No callbacks either project with Intelligent Membranes - Passive Purple project in West Town finished in Oct 2025 and roofing project in Lincoln Park finished in Dec 2025. A current project on the North Shore using Passive Purple should finish Sept 2026.

We used the Passive Purple and tanking system for our bathroom. Both products were fantastic, delivery was exceptionally fast and extremely affordable. Would recommend.

Great product delivered as promised.

Used Intelligent Membranes twice now and both times the service has been great. Quick delivery, and a great easy to use product. Will definitely use again.

My Builder forgot to put a vapour control layer (VCL) on my Timber Frame and Brick Clad bungalow.

I was looking at having to remove the internal plaster work throughout the entire building and retrofitting a VCL and then re-plaster boarding and skimming the entire interior.
Luckily, I came across Intelligent Membranes. They sell a product that Acts as a VCL.

It’s a sprayable Paint that the new build warranty company, Buildzone accepted as an alternative and a remedy to the lack of VCL.

Intelligent Membranes gave me all the paperwork to send to Buildzone.

I could not believe my luck that this product exists and could fix the problem and save me an absolute fortune.

Adam and his team at Intelligent Membranes were really very helpful and I cannot recommend them highly enough

Working with Intelligent Membranes for may years now, they have always been a pleasure to deal with, in particular Tanisha Fountain, who is always on hand if we need any further information for they're deliveries etc.

Product was shipped promptly.

Communication throughout was accurate and reliable.

Product was excellent.

An extremely helpful and knowledgeable team with real-world expertise in building Passive Houses. Their ability to tackle construction challenges is invaluable. I've used many of their products, and in tricky situations, their solutions have been the only ones on the market that worked. Thanks to them, I've achieved results below 0.1 ACH a number of times. They've saved the day for me more than once—thank you!
