Selecting the Right Cavity Closer

When choosing a cavity closer, consider the following:

  • Fire Safety Requirements: For buildings where fire safety is paramount, opt for fire-rated cavity closers.
  • Thermal Insulation Needs: If energy efficiency is a priority, insulated cavity closers are the best choice.
  • Installation Type: Check reveal cavity closers are ideal for precise installations around doors and windows.

  • Project Scale: For larger projects, multi cavity closers provide an efficient solution.

     

Remember, the right cavity closer not only enhances the structural integrity of your build but also contributes to energy efficiency and safety compliance.
