INTELLO PLUS, SOLITEX MENTO, and most of our membranes are sold in 807 square foot rolls. For each roll of membrane, you’ll need an average of 2-3 rolls of the corresponding airsealing tape.

There are a few exceptions which are noted on the product pages. Please email info@475.supply if you would like support with sizing an order.

The correct tape to use is nearly always TESCON VANA, also known as 'VANA' for short. VANA comes in a variety of widths. For simple airsealing of membrane, the standard 2 3/8" width is the one to use. The only time to consider something other than 2 3/8" TESCON VANA is for window rough opens or building corners (wider varieties of TESCON VANA will be more useful), when using SOLITEX FRONTA QUATTRO in an open joint rainscreen application (use TESCON INVIS), or when the membrane is already integrated with adhesive strips (such as SOLITEX UM Connect or ADHERO).

At 475 High Performance Building Supply, we believe that when it comes to foam, less is best. Foam, derived from petrochemicals, can release toxic gases throughout its lifetime, is inflexible and experiences shrinkage and cracking that can dramatically compromise building performance, and presents a significant fire hazard. These and other foam-related problems are covered in our “Foam Fails” blog series.

Building a foam-free, high-performance home is possible - so we believe in making the choice that’s healthier for occupants, better for the planet, and more likely to guarantee long-lasting high-performance buildings.

The best way to design your foam-free roof assembly depends upon the type of roof and building you’re designing, your climate zone, and your building preferences. While we advocate for vented roofs, we understand that not every project will have one. The blog posts below cover a range of roof assemblies, from flat to vaulted, vented to unvented - and how to ensure long-term performance no matter which path you choose.

Ensuring an airtight connection between your high-performance windows and the rest of your air barrier can be one of the biggest airsealing challenges, but doing so properly is indispensable for robust, long-term airtightness. Selecting the right tapes, pre-making window tape corners, and identifying how and where to tape the frame, air barrier, and window bucks will all help you meet these goals. Check out the posts below for our guide to the best window airsealing practices.
