SureSeal Drywall Gasket Tape ensures an airtight seal so that air from the wall cavity will not infiltrate around the top or bottom of the drywall. No more cold drafts coming from behind the crown molding or baseboards.
Simply peel and stick to the face of the top plate and bottom plate, then install drywall as normal, making sure to use drywall screws. Take care not to stretch the foam.
Yes, our adhesive is very aggressive and will hold up to the shearing force applied when sliding drywall over it.
Yes, in fact the longer SureSeal stays in place, the stronger the bond between the foam and the framing.
No, our adhesive takes the place of the labor intensive stapling process.
Our 3/8″ X 1/2″ size is the most common size used for drywall applications. However, both narrower and wider sizes are available.
For our 3/8″ thick foam, between $0.10 and $0.20/foot, depending on the width you choose.
The first step is estimating the amount of feet you will need. Then either go to the “Contact Us” page, and either call or email. We will work with you to determine the correct size and quote a price.
Currently we sell direct from our facility in Michigan, and ship right to your door.
Yes, just call or email and we will get a sample of SureSeal out to you right away.

Gaskets are gaining in popularity as sealants in housing. Here are the options – and a vote for the saturated urethane variety.
New materials and techniques make it easier to build today’s tight, energy-efficient homes. One system that has won many converts is the airtight drywall approach (ADA). ADA relies heavily on the use of foam gasketing – a product that our company has manufactured for more than 20 years.
In the ADA building system, nearly all joints – sill to foundation, band joist to sill, subfloor to band joist, wall plate to subfloor, and drywall to frame – are gasketed with foam tapes. The combination of gaskets, drywall, and caulk creates an airtight envelope. Foam gasketing tape is well suited for many of these joints because it is clean, economical, and easy to apply. The right gasket will maintain the seal even if the joint moves, and won’t squeeze out of the joint under compression. Caulk, on the other hand, is messy, hard to apply, and will bleed out of the joint when compressed.
What foam-sealant tapes are available? Which ones should builders use and why?
Low-density, closed-cell foams such as PVC and ethyl foam take an absolute “compression set.” Once compressed, they remain fully, or almost fully, compressed. If a joint opens up over time, the seal is lost. And closed-cell materials can only be compressed about 50 percent before cell walls begin to rupture. They are like balloons that have been squeezed so hard that they pop, and can no longer hold air. Under complete compression, most cell walls will break and the gasket cannot form a seal. Add these shortcomings to the fact that closed cell foams are typically quite expensive. Because of these shortcomings, low-density closed cell foams do not serve well in building applications. Ironically, they are the most commonly used foam gasketing products today.
High-density closed cell foams (Neoprene, EPDM, closed-cell urethane) are very difficult to compress and not very moldable. They are hard to compress because they have smaller cells and tougher walls. As with their low density cousins, if these are compressed beyond 50 or 60 percent, their cell walls will break. Within their range of compression, these materials take a slight compressions set – they restore almost to their original size. Whiel high-density closed cell foams are high quality materials, they aren’t particularly useful in structural joints because they can’t be fully compressed and they don’t mold well to irregular or rough surfaces such as concrete or wood.
Polyurethane is tough. Its structure is composed of millions of triangles and rectangles tied together. This structure gives it a minimal compression set. But open-cell urethane foam (found in pillows and mattresses) is not a sealant, because the cell walls are not complete. “Open-cell” refers to the gaps in the cell wall. Also, urethane foam degrades rapidly under the onslaughts of ultraviolet light and ozone. It makes a gret cushion…but not much of a gasket.
To make use of urethane’s good properties while overcoming its deficiencies, the industry has developed saturated foam gaskets. The saturant, which partly fills the cells in the foam, can be a wet adhesive sealant or a dry sealant such as rubber or wax. Only open-cell foams can be saturated. The purpose of saturation is twofold: First, it dramatically improves the sealability of urethane by closing the cell walls. Second, the saturant protects the cell walls from degradation. It is easy to compress saturated urethane foam to approximately 10 percent of its original thickness without harming the product. Under full compression, the cell walls rupture as with closed cells, but are then reformed with saturant.
Saturated urethanes generally are available in precompressed rolls that expand to the original dimension after being released fro the roll. They are elastic sealants that always recover, even after being completely compressed. Some saturated urethanes recover faster than others, depending on what saturant is used, but all exert a force to recover because they are urethanes. In the construction industry, where gaskets are likely to be buried permanently within the framework, saturated urethane foam gaskets really make sense.
For many building applications, a 3/8 inch thick by 3/8 to 1/2 inch wide gasket is suitable, although sizes are best discussed with our inhouse staff prior to ordering.
