Stop Wasting Time
Grease Ducwork Installation Savings


CL4FIRE announces unique time saving single layer grease duct system tested to the latest UL standard CAN/ULC-S144. The CL4FIRE single layer system is the latest improvement over the standard 2-layer systems previously offered.

Space saving butted seams, material savings from no overlaps, and just ONE LAYER of 72mm (3”) thickness.

Sure, 72mm is a little heavier than installing a 36 mm layer. But it is easily manageable with the newest CL4FIRE lighter 6 lb. density insulation.

And it saves up to 50% of the installation time!
