Sill seal is ribbed polyethylene foam used to seal the gap between the sill plate and the foundation. Lightweight and resilient, it is easy to cut to length and installs without tools. The ribs effectively seal out air currents, moisture and insects, leaving you worry free to enjoy your home.

Can pressure-treated wood sit on concrete?
Wood on Concrete or Other Masonry
Pressure-treated wood is not required if an impervious moisture barrier and a 1-inch metal or masonry pedestal separate the post from the earth by a total of 6 inches in basements or in weather-exposed locations.
What goes between sill plate and foundation?
The best way to air seal the sill plate is to place a sill sealer (also called a sill gasket) on the concrete before laying the sill plate over the foundation. A sill seal product that covers the whole sill plate area is preferable because of its waterproofing capability and inherent uniformity.
Is sill seal waterproof?
Sill sealers self-adhesive – easy application – weatherproof. Combination of 3/8 inches closed cell polyethylene foam with an aggressive self adhesive waterproofing membrane. Conforms and seals off the voids and irregularities between the top of the foundations and sill plate.
Do sill plates need to be pressure treated?
You need pressure treated lumber when: Sills and sleepers on a concrete or masonry slab that is in direct contact with the ground unless separated from such slab by an impervious moisture barrier. This includes the footing.
What do you use to seal wood to concrete?
I recommend using an exterior silicone formulation for concrete or a high-quality polyurethane sealant. Both will stick well to the wood and the concrete. Acoustical sealant is a better, albeit slightly more expensive, option. Caulk often works best at a slab-wall transition.
How thick is a sill gasket?

What should I put between 2×4 and concrete?
In most cases, either pressure-treated lumber or naturally durable lumber (defined by the IRC as the heartwood of redwood, cedar, black locust, and black walnut) is acceptable. In some cases, separating wood from concrete with a water-impervious membrane or vapor retarder is all that’s required.
How long will a treated 4×4 last in concrete?
How Long Will A Treated 4×4 Last In The Ground? (Explained) A treated 4×4 will last 20 to 25 years in the ground if the conditions in the soil and climate are favorable. That number could increase to 40 to 75 years if you install the treated 4×4 in a cement ring rather than the soil.
Why is pressure treated wood cheaper?
Affordability. Pressure-treated wood is notably cheaper than cedar, redwood, and other types of wood. And, because of its durability, you’re much less likely to experience a need for costly repairs in the future. It is a great choice for those operating on a smaller budget.
