WHAT IT IS

A turbine ventilator throat flashing (base plate) is a profile-matched waterproofing component that seals the penetration where a turbine ventilator or roof vent passes through the roofing sheet. Fabricated in aluminium or lead, formed to replicate the exact corrugation or trapezoidal profile of the host roofing sheet (e.g., Trimdek, corrugated, standing seam). A self-sealing mastic or neoprene gasket at the base prevents water ingress at the roof penetration. Throat collar is sized to match the ventilator diameter (8", 12", or 14"). Critical in Malaysia's high-rainfall tropical climate to prevent leaks at any roof penetration point. Typically supplied with a turbine ventilator set or purchased separately.
