A styrene upstand trim is designed to create a vertical termination where the roofing membrane meets an upstand, such as a wall, parapet, skylight upstand, or other vertical detail. This trim ensures a clean, watertight finish and enhances the overall durability and appearance of the roof edge with nails and joining clips included.

Key Features:

• Manufactured from high-impact styrene (HIPS), chosen for its toughness, UV resistance, and compatibility with roofing resins.
• L-shaped or right-angled profile, with a vertical face that runs up the adjoining surface and a horizontal flange that sits over the roof deck.
• Directs water away from vulnerable joints and prevents ingress at the base of upstands or vertical structures.
• Smooth, often in black, white, or grey to match other trims and maintain a uniform appearance.
