Frequently Asked Questions
What's the best way to apply foil tape?

We've heard from many customers who've had great success using a simple Wallpaper Roller to smooth out their foil tape, giving a very smooth, clean look on your ducting. The roller helps smooth out air bubbles and crinkled marks while making it easier to get those hard to reach places on hanging ductwork.We do not carry this product but it can be found easily at your local hardware store or home renovation outlet.
