RESTRIM Flat Sheet F300 — 300 mm Flat Flashing Trim (20 m & 3 m)

The RESTRIM Flat Sheet F300 is a pre-formed GRP (glass reinforced plastic) flashing sheet designed for continuous, seamless transitions where a pitched roof meets a flat roof or in other interface zones. Offered in two packaging options — a full 20 m roll or a 3 m cut length — it provides flexibility and ease of installation to suit varying project scales.

Key Features & Benefits

• Precision-engineered GRP: Manufactured with the same robust material standard as the rest of the RESTRIM / RES TRIMS family, ensuring durability, UV stability, and weather resistance.
• Flexible yet stable: Allows for minor surface irregularities and alignment during installation while maintaining dimensional integrity under load.
• Seamless flashing continuity: Used as continuous flashing beneath slate or tile abutments, the F300 helps prevent water ingress at critical junctions.
• Gutter-lining capability: Can also serve as internal lining for box gutters or similar details, offering dual-purpose utility.
• Easy jointing and finishing: Overlap joints (typically 50 mm) can be bandaged and resin-sealed to preserve continuity and structural integrity.

Multiple length options:

• 20 m roll: allows long continuous runs with minimal joints  
• 3 m length: ideal for smaller details, stock management or site cut backs

Compatibility: Fully compatible with RESTRIM / RES TRIMS accessory trims, adhesives, and GRP roofing systems.
