Getting started with Instafit®

How to install Instafit®?

Before you start

  • Instafit® can be fixed mechanically or with adhesive dependant on application. The boards can be fitted vertically or horizontally internally within the dwelling as well as in cavity wall applications (see building regulation guidance for the UK). The joints between boards can then be sealed with tape.
  • Take account of any electrical cabling or hanging brackets, such as for heating elements. Work out where they need to be in advance.

The Instafit® can be used to insulate your floor, ceiling, loft and internal wall. Access the installation instructions suitable for your application here.
