Independent reviews of Intelligent Membranes, collected and verified by Trustpilot — rated Excellent by the builders, architects, contractors and self-builders who use our products on site every day.
From Passive Purple, the world's first Passivhaus-certified liquid-applied airtight membrane, to our vapour control, waterproofing, smoke-tight and fire-protection coatings, the reviews below cover real projects across the UK: new builds chasing exceptional airtightness scores, Passive House projects, and retrofits cutting heat loss and air leakage. Spray or roller applied, our airtight paint systems replace tapes and sheet membranes with one seamless coat.
Every review is verified by Trustpilot, an independent review platform — we can't edit or remove them. If you've used Passive Purple or any of our membranes on your project, we'd love your feedback below.
