Paintable Exterior Surface - easily Blend In to your exposed applications
For exposed applications, InspiralR and Floval have an exterior surface that can easily accept water based paints. This can allow your application to achieve a specific aesthetic look without the need of any special treatments. InspiralR and Floval offer a clean, even look without the need for additional insulation wrapping that can often give traditional insulated duct an uneven or lumpy exterior.
