Look like lead, behave like GRP. C100 replaces traditional lead flashing with a dark-grey, non-adhesive finish that simulates lead — without the theft risk. It self-secures in a chased mortar joint via an integral return; seal with compatible mastic. 

Why roofers pick it

• Lead-look finish without scrap-value headaches.
• Self-securing chase detail for neat, lasting abutments.
• System fit: install after you’ve laminated the wall junction with RORR.

Specs (typical)

• Length: 3 m | Visible face ~100 mm.
