Insul-Baffle
Description

Masons Insul-Baffle is a crenelated semi-rigid synthetic spacer. Made from clear plastic. it is installed over the rafters or truss top chords, typically near the eaves, where it is likely bulk thermal insulation may push up against the roof underlay.

  • Masons Insul-Baffle is designed to separate roof underlay from bulk insulation where these elements may come into contact, or the required 25mm gap between them cannot be maintained. It assists in meeting the requirements of NZS 4246:2016.6.2.10.
  • It also allows a path for air movement as part of a passive–stack ventilated roof space design. Masons Insul-Baffle incorporates ‘Dragon Channels’ to increase rigidity and aid air to cross flow.
