B2B Specifications // EWI Accessories
Engineered for External Wall Insulation (EWI) systems. Fits securely under sills and soffit boards, ensuring rainwater falls clear of the render envelope while minimizing on-site sealant usage.
WARNING: FAILING TO SHED WATER CLEAR OF RETROFIT REVEALS LEADS TO FACADE STAINING AND INSULATION CORE MOISTURE.
Water Management
The **Dropdown Verge Trim** is optimized for applications where fixing must be carried out from below the projection line. It sits flush beneath window sills or eaves soffit boards, creating a mechanical barrier.
By diverting water downwards and outwards, it ensures that wind-driven moisture cannot track back along the underside of the sill and penetrate the render boundary. This design eliminates the common failure points of wet sealants and expanding foam tapes.
All on-site surveys, reveal drawings, and professional fitting of verge trims are carried out by our parent company, **CILLS LTD**, ensuring safe pass compliance and workmanship guarantees.
