Self-stick plastic (vinyl) folded along length in a V-shape or a springy bronze strip (also copper, aluminum, and stainless steel) shaped to bridge a gap. The shape of the material creates a seal by pressing against the sides of a crack to block drafts.
Inside the track of a double-hung or sliding window, top and sides of door.Moderate; varies with material used.Durable, invisible when in place, very effective. Vinyl is fairly easy to install. Look of bronze works well for older homes.Surfaces must be flat and smooth for vinyl. Can be difficult to install, as corners must be snug. Bronze must be nailed in place (every three inches or so) so as not to bend or wrinkle. Can increase resistance in opening/closing doors or windows. Self-adhesive vinyl available. Some manufacturers include extra strip for door striker plate.Felt:
Plain or reinforced with a flexible metal strip; sold in rolls. Must be stapled, glued, or tacked into place. Seals best if staples are parallel to length of the strip.
Around a door or window (reinforced felt); fitted into a door jamb so the door presses against it.LowEasy to install, inexpensive.Low durability; least effective preventing airflow. Do not use where exposed to moisture or where there is friction or abrasion. All-wool felt is more durable and more expensive. Very visible.Reinforced foam:
Closed-cell foam attached to wood or metal strips.
Door or window stops; bottom or top of window sash; bottom of door.Moderately lowEffective sealer, scored well in wind tests, rigid.Can be difficult to install; must be sawed, nailed, and painted. Very visible. Manufacturing process produces greenhouse gas emissions.Tape:
Nonporous, closed-cell foam, open-cell foam, or EDPM (ethylene propylene diene monomer) rubber.
Top and bottom of window sash; door frames; attic hatches and inoperable windows. Good for blocking corners and irregular cracks.LowExtremely easy to install, works well when compressed, inexpensive. Can be reinforced with staples.

Pliable or rigid strip gasket (attached to wood or metal strips.)
Door or window stops; top or bottom of window sash; bottom of a door (rigid strip only).Low to moderateEasy installation, low to moderate cost. Self-adhesive on pliable vinyl may not adhere to metal; some types of rigid strip gaskets provide slot holes to adjust height, increasing durability. Comes in varying colors to help with visibility.VisibleDoor sweep:
Aluminum or stainless steel with brush of plastic, vinyl, sponge, or felt.
Bottom of interior side of in-swinging door; bottom of exterior side of exterior-swinging door.Moderate to highRelatively easy to install; many types are adjustable for uneven threshold. Automatically retracting sweeps also available, which reduce drag on carpet and increase durability.Visible. Can drag on carpet. Automatic sweeps are more expensive and can require a small pause once door is unlatched before retracting.Magnetic:
Works similarly to refrigerator gaskets.

Well-maintained wood windows with quality weatherstripping are absolutely competitive with modern counterparts. In fact, newer replacement windows have estimated lifespans of only 15-20 years, whereas original 100 year old wooden windows that are properly cared for are still going strong today and will continue to last a century more.
Weatherstripping seals the openings of your doors and windows. This process prevents air loss and protects any unwanted things from getting into your home, such as rain and insects.
Weatherstripping is essential to making original wood windows and doors airtight and energy efficient. There are many advantages to installing weatherstripping, and when you choose our weatherstripping, your efforts will last for decades.
There are many choices for weatherstripping on the market. Self-adhesive wool and foam may seem simpler to install. Vinyl and silicone weather strip may be cheaper. However, metal interlocking weatherstripping is far superior and longer lasting than these wimpy, lower-quality materials. Instead of a product that will crush over time and wear out, metal interlocking and spring bronze weatherstripping is incredibly rugged and will last for many years.
Weatherstripping isn’t only for keeping out cold winter winds. In warm climates, it helps keep air conditioning and cool air in. It is also one of the best sound proofing efforts you can imagine. Keeping drafts from traveling in and out of your home also improves indoor air quality considerably, preventing allergens and other harmful airborne toxins from entering your building. If you have noisy neighbors, a nearby train track, or a teenage drummer, it also is an excellent soundproofing material.
A common complaint about older wooden windows and doors is that they are heavy and stick during operation. Previous attempts at sealing up leaks with wool batting and layers of paint take away their original beauty and can render them useless. These products don’t add any friction to window action. Once Window Restoration Supply's weatherstripping is installed, owners are amazed at how easily their windows glide up and down, how smoothly their door operate, and how tightly these architectural components seal for the airtight operation they always wished for.
Owner, Marc Bagala, has 35 years’ experience installing weatherstripping and knows first-hand of the value of the the original products. It was learning and installing the original Accurate Metal Interlocking Weatherstrip that launched Marc’s window restoration career. When the original Accurate company, after over 100 years in operation, decided to close their doors in , Marc knew he had to purchase some of the custom-designed and made roll forming machines from the company to carry on manufacturing. His window restoration company had come to depend on the metal interlocking products to give his own customers superior weatherstripping advantages. He knew these products had to remain available to building owners, contractors and installers.
Marc believes that if it wasn’t for the original metal interlocking weatherstripping products, tens of thousands of wood windows would be lost and we wouldn’t be restoring all the windows we are today. "It's the best weatherstrip for stopping air infiltration, and keeping it out.”
People refer to Marc in the preservation world as “the weatherstripping guru” – he doesn’t mind it!
“We believe using these products gets you on the 100-year care plan when we are done with repairs and weatherstripping – giving more than a lifetime of satisfaction!”
Today, he and his brother, Carl, run the original 100-year old machines and continue to manufacture the weatherstrip they depended on for decades. They have run across just about every conundrum that can happen while weatherstripping a window or door, and this website is the perfect place to share their experience and passion – as well as these great products!
