Manthorpe WCMULTICOR150 Multi-Width Cavity Closer - Pack of 6

The Manthorpe WCMULTICOR150 Multi-Width Cavity Closer – Pack of 6 is a robust and practical solution for creating thermal breaks around window and door openings in wider cavity wall constructions. Designed for cavity widths between 100mm and 150mm, this closer not only reduces heat loss but also acts as a vertical DPC at the jambs to prevent moisture ingress.

With built-in groove guides, each unit can be easily trimmed on-site to match the required cavity width, offering a fast and flexible fit. When fitted with a 30mm overlap behind the window or door frame, the closer helps achieve the required R value for thermal resistance at the reveal, supporting compliance with modern building regulations.

Manufactured using low GWP insulation, the WCMULTICOR150 contributes to environmentally conscious building design and is suitable for both new build and retrofit cavity wall projects.
