Product Introduction

This version increases the rigid core depth to 30 mm while maintaining thin aluminum facings. It fits indoor supply routes where the temperature difference is greater and a thicker thermal layer is desirable without adding a separate external wrap.

Key Features

Deeper core adds thermal resistance to the duct shell.
Rigid panels preserve a defined rectangular air passage.

Solutions for Your Application

Surface temperature is too low with a thinner duct wall.

The increased foam depth reduces heat transfer through the panel.

Adding insulation later would interfere with nearby services.

The selected wall incorporates the additional thermal layer from the outset.
