Collection: Passive Purple X

Passive Purple X is Passive Purple with a fire rating — an airtight, vapour control membrane achieving reaction to fire Class B, available in white, black and cream as well as the signature purple. Spray, roller or brush applied over blockwork, OSB and timber wherever the specification calls for fire performance and airtightness in the same coat. This collection pairs it with the rest of the airtight system — Passive Purple, Airtight White, sealants, tapes and primers — so you can pick up everything the job needs in one order.
