Compare InspiralR to Doublewall Metal Ductwork to See if Your Current Duct Might Be Weighing You Down
Lightweight and easy to install, InspiralR and Floval can drastically reduce the weight of installed spiral and flat oval by up to 75%. Because it is pre-insulated, there is no need to insulate separately.
With less weight hanging above heads, engineers and building owners can rest easy as their installation safety concerns can be addressed with InspiralR and Floval.

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.
With the lower leakage rates and R-6 phenolic insulated values offered by these high efficiency systems, dust accumulation will be prevented from having streaks caused by air leaking out or condensation dripping down the ductwork.
InspiralR & Floval are engineered to perform and can be customized to match your application. The only difference you'll notice is with your utility bills!
Installing Pre-Insulated Round and Flat Oval
We designed our round and flat oval duct systems to be familiar to contractors. Standard spiral flanged connections allow InspiralR and Floval connect fast and easy.
These flanges can come in a variety of materials and finishes including galvanized (standard), aluminum, stainless steel or powder coated galvanized.
