Our 3mm is now on clearance! We are updating the 3mm to make it even better and offering this current lot on clearance sale of $239/roll.
Curious what's changing? We are moving the adhesive onto the foam and doing away with the tape tab.
Why? Well, quite frankly, the 1" seal wasn't good enough for us to say it was the best. In real-world examples the 3" seam tape covered more surface area and created a tighter seal. Since air-tightness is such a critical part of condensation control, we want to improve this product to make it the best!
Is this a good offer? Yes, you won't see low pricing like this on the 3mm again! Don't worry though - when you buy the 3mm Pro, we will include 1 FREE roll of our 3" wide seam tape for each roll of insulation you buy. This way you can have everything you need to seam it right. When you consider the discounted insulation price + the free tape offer - this is a STELLAR DEAL you won't see for long. Offer good while supplies last.
