Cavity Closers

Emereo can now manufacture pre-formed uPVC cavity closers to help your project run as smooth as possible.

Cavity closers have become a critical building component that’s now widely used in all commercial and residential new-build projects. They are undoubtedly the simplest and most effective way to seal cavities around wall openings and provide a rigid template for bricklaying and window or door installation.

These cavity closers provide a quick, easy and cost effective way of forming a window or door opening, acting not only as a pre-made template for building, but also as a rigid insulated DPC whilst minimising the effect of thermal bridging.

Here are a few of the major benefits at a glance:

  • Manufactured from 100% post-consumer UPVC
  • Pre-installed polystyrene core enhances thermal efficiency for Part L compliance
  • Time saving clip together assembly – no adhesives or tools required Quick-fit spring clip for fast installation of pre-glazed windows
  • Compatible with most UPVC window systems as well as timber and aluminium

Our range of innovative Cavity Closers won’t just help you meet today’s sustainable legislation, but that of the future as well. The insulated back box gives excellent thermal performance and means that openings can be closed with continuous insulation.
