The multi-width cavity closer will suit standard cavity widths between 50mm & 100mm, not only providing a thermal break to the cavity but also acting as an effective vertical DPC barrier at the jambs. The WCMulticor can be quickly and accurately cut down by the user to suit various widths of cavity by using the groove guides. The closer achieves the required thermal resistance (R Value) at the reveal of door and window openings when the frames are fixed to allow a 30mm overlap into the cavity.
- Double flanged profile from a single extrusion
- Multi Width insulation options from 50 to 100mm cavities
- Closer acts as a vertical DPC at the jambs
