The Cavalok Trade cavity closer is a simple, versatile insulated dpc closer designed for use on refurbishment projects, or on new-builds where a decision to use cavity closers has been made after the walls are built. Pre-insulated, 100% recycled cavity closer.
Like other Cavalok cavity closures, the Trade closer features integral insulating foam that 
can rapidly improve thermal performance at door and window openings in existing buildings. It’s also manufactured from post-consumer recycled PVC-U – plastic that would otherwise be sent to landfill.

Sizes to suit your project
The simple design makes it compatible with all types of cavity wall of any age – it just slots into place between the walls around your building openings. The Trade Closer is a one size product, supplied at 100mm, smaller sizes are acheived by trimming down the insulation along pre-cut lines.


One size fits all 50mm,  75mm and 100mm (2",3" and 4") cavity fulfilled . No Wastage . 2 Pre-cut grooves for easy snap-off of  polystyrene to desired width. Grooves down the length of the closer for easy 'Keying in'.
