Send Us Your Drawings — Free Technical Advice & Markup
Not sure where the airtight line runs on your project? Send us the drawings — we’ll mark them up for you.
Our technical team reviews architectural drawings and details every week for architects, specifiers, contractors and self-builders. We’ll show you exactly where Passive Purple, fleece tape, sealants and primers go, flag the junctions and penetrations that fail air tests, and recommend the right products for your build method — timber frame, blockwork, ICF, steel or retrofit.
What we do with your drawings
- ✏️ Mark up the airtight and vapour control line — product by product, junction by junction
- 🔍 Flag the weak points — joist ends, window reveals, service penetrations, floor-to-wall junctions
- 📋 Recommend the spec — which product, which grade, coverage rates and application method
- 🌡️ Condensation risk — we can run a condensation risk analysis on your build-up
- 📐 Need standard details? Browse our detail drawings library
