Windows, Sills & Seals: Getting Flashing Tape Right on Site
Flashing tape might seem like a small detail but it plays a critical role in protecting buildings from moisture and air leakage.
In Episode 3 of The Masons Podcast, Michelle is joined by Masons Technical Manager Arthur Whitfield to explain how flashing tapes work, where they’re required, and how proper installation supports weather tightness and compliance in New Zealand buildings.
They discuss flashing around windows and joinery, air barrier sealing, compatibility with underlay systems, and the common mistakes that can reduce performance. Arthur also shares important installation advice.
This episode also includes a key product update: Masons 40 Below flashing tapes now require only one layer on the sill to achieve screw sealability.
Whether you're a builder, designer, or specifier, this episode delivers practical knowledge to help you make better decisions on site and at the drawing board.
