SureCav - New Technology in Cavity Wall Construction! 

Provides up to 5% extra floor area when using original external dimensions!

SureCav is a moulded, recycled, polypropylene panel with spacer protrusions that forms the cavity and allows a stone, slate, brick and flint outer skin to be built without the need of an additional block leaf. This cavity protection system ensures clean and moisture free cavities.
