Latest Innovations In Facade Framing Systems

Soffit System

Soffit system-white 3

CLAD-LINE’S CL1-S soffit system is suitable for face fixed soffit panels and discrete fixed cassettes.

Soffits to un-heated areas are frequently not insulated but if thermal bridging is an issue, flat isolation pads can be supplied to limit thermal transmission and prevent bimetallic corrosion.

T rails are fixed to the bottom of the ‘dropper’ L rails where panel joints occur. For intermediate and panel end support, CLAD-LINE’S L rails can be used.

CLAD-LINE hold extensive stock of both T and L rails and can fabricate in house to exact customer requirements. The CL1-S system can also be used to create sloping soffits through cutting of the rails to the required angle.

The CL1-S Dropper Rail connects to the CL1-S Bracket. Often soffits are not insulated but if thermal bridging is an issue flat plastic isolators can be supplied. Alternatively the CL1-S Bracket can be supplied with an A2 fire rated isolator.


The CL1-S Dropper Rail is supplied to suit drops up to 1m in depth. Due to the nature of the system, the dropper rail can be easily adapted on site. CLAD-LINE’s range of T and L Rails can be used as the main cladding support rail.
