Material & Build

Crafted with black EPDM, this flashing combines durability with elasticity—resisting UV, ozone, heat, cold, and harsh environmental exposure. A red high‑temperature silicone variant is also available for installations with elevated heat conditions The rigid aluminium base conforms easily to metal roof profiles and accommodates standard panel heights.

Available Variations

Colours: Black EPDM, grey EPDM, red silicone
Material Options: EPDM for standard use, silicone for extreme temperatures, and custom colours upon request
Solar Port Sizes: While the twin-port covers 0–35 mm conductors, MasterFlash also offers single ports for 0–50 mm and up to 70 mm, as well as multi-ports for larger systems
Base Types: Square aluminium base is standard; tile bases and lead bases are available for other roofing types

Why Choose This Flashing

Dual conduits in one: Streamlines installation and reduces roof penetrations
Highly weatherproof: EPDM resists UV, ozone, and thermal stress; silicone option handles intermittent heat spikes to 260 °C
Simple install: No hot works required; cut ports to size, attach via pre-marked aluminium base, and seal with quality roof-gutter silicone
Versatile compatibility: Suitable across various metal roof profiles and up to 45° pitch

Applications

Ideal for solar PV installations where two conductors exit a panel clamp or junction box. It also suits dual pipe systems on thermal solar setups, or any twin-cable rooftop wiring scenario. A single-base fit keeps the roof clean and flashings professional.

The MasterFlash Solar Twin Port 0–35 mm Black is a durable, dual-purpose flashing tailored for contemporary solar installations. With its EPDM sleeve, aluminium base, heat-rated silicone alternative, and 25-year warranty, it offers installers a highly reliable, clean, and efficient method for sealing dual penetrations through metal roofing.
