Grille Boot – 900 x 450 with 350Ø Top Entry

Lightweight R1.0 Insulated Grille-to-Duct Adaptor

Not your average grille boot.

Manufactured by Airflow Engineering, this insulated grille boot provides a strong, lightweight connection between a 900 x 450 mm grille and 350 mm Ø duct.

The boot combines a 100 mm deep steel grille frame with a lightweight PIR pre-insulated panel body and metal duct spigot, providing a robust finished fitting without the weight of a fully sheetmetal insulated boot.

With an insulation rating of approximately R1.0, the PIR construction provides the required insulation as part of the boot itself, eliminating the need for additional external lagging.
