Air, Comfort, Energy Savings Aeroseal - Leak Sealing for Clean Air, Comfort, Energy Savings

This type of caulk can expand and fill up larger spaces using polyurethane spray foam insulation, making it perfect for areas around leaky electrical outlets, pipes, and window jambs. The aluminum duct tape can be used to seal just about anything in the ductwork, from loose connections to small leaks or holes. After using the aluminum duct tape, use ductwork mastic such as the one linked here to go over it. This seals any seams from the duct tape and gives some extra strength to make sure the air leakage points stay completely sealed. Maine builder Dan Kolbert, for example, used Siga’s Majvest 500 on the exterior of a double-stud wall house his company built recently. The fully-adhered membrane is windproof and rainproof, according to the manufacturer, but it’s also diffusion-open so any moisture inside the wall can dry to the exterior as well as the interior. Another option is Henry’s Blueskin. Siga’s Majvest 500 is a self-adhering, vapor open membrane that creates an air seal on the outside of the sheathing. Photo courtesy Scott Gibson.

In summary, latex caulk is a good choice if you’re looking for a caulk that is easy to apply and will work for most indoor applications. However, if you need a caulk that will withstand exposure to moisture, extreme temperatures, and UV radiation, then silicone caulk is a better choice. Summary Taking on air-sealing as a DIY project can be similar to a house-sized puzzle. You will need to identify the air leakage points and appropriately seal them off. It can seem overwhelming, but if you are methodical and organized about finding the leakage points, marking them, and then performing the fixes, it should be a fairly smooth and easy process. One of the best butyl-rubber caulk products on the market is the Flex Shot Rubber Adhesive Sealant Caulk. It is affordable and reliable, making it an excellent choice for home improvement projects where small holes may leak air into the home.

Clean up any excess caulk with a rag, and let it sit undisturbed for about a day. How long the drying process takes depends on your product and the humidity and air temperature. FAQs Will caulking keep cold air out? If you live in a location with extreme hot or cold weather, where heating or air conditioning is used for a significant portion of the year, it is advised to install ductwork insulation as well. The insulation prevents the heat or cold itself from escaping through heat transfer. If hot or cold air is flowing through your ducts, the aluminum ducts will also get warm or cold which will, in turn, be transferred to the air. When it comes to caulking, latex caulk is a popular choice because it’s versatile and easy to use. Acrylic latex caulk is perfect for filling gaps in drywall, wood, and masonry and can also be used for crown molding and baseboards.

Tremco’s Curtainwall Sealant also can be used as a lap joint and perimeter sealant for polyethylene vapor retarders. The ceiling between the uppermost story and the attic is a notorious source of air leaks. The tops of partitions, electrical and plumbing lines, HVAC chases, can lights—they’re all potential sources of warm, moist air for an unconditioned attic. Some builders install poly sheeting or a layer of OSB (with taped seams) here as an air barrier, but manufacturers also offer vapor permeable membranes as an alternative. Builders concerned about the potential for trapping moisture in wall and ceiling cavities can chose vapor-open membranes for both interior and exterior air barriers.

Most of the tapes did well on housewrap, while foil-faced polyisocyanurate insulation also proved easy to tape. Here, brand didn’t seem to matter very much (there were, however, some exceptions). Furthermore, Air-Seal Products offers financial advantages on two fronts. First, the tyre sealant’s puncture repair reduces downtime and replacement expenses. Second, the improved fuel economy lowers operational costs, especially for businesses with large fleets or industrial operations. Do building scientists sometimes wake up and feel like Bill Murray in “Groundhog Day,” trapped in a time loop where no matter how many times they try to explain the importance of air-sealing nobody listens? It must have seemed that way at times, but builders and building codes are gradually heeding their advice and houses are slowly but surely getting tighter—and the result is lower heating and cooling bills, healthier indoor air, and more durable structures. Not necessarily. Think of your house like a boat. If you have a dozen small holes, the water will add up, and your boat will sink.Builders are becoming more proficient with air-sealing techniques and materials, but with a little perseverance even non-pros can make remarkably tight structures. One of them is Eric Whetzel, whose work on his own home in the Chicago area has been detailed in a long-running blog at GBA called “Urban Rustic.” Eric invested thousands of dollars and many hours in air-sealing his house. These coatings are made by several manufacturers. Others include Prosoco ( Spray Wrap MVP), GCP ( Perm-A-Barrier), W.R. Meadows, ( Air-Shield), BASF ( MasterSeal AWB 660), and IMETCO ( IntelliWrap). Caulks and sealants On the inside, one option for sealing the rim joist is with a layer of spray polyurethane foam. The foam gets into the oddly shaped spaces that make insulating this area so difficult with conventional products. Builders also may cut pieces of rigid foam to fit between floor joists and foam them into place with canned foam, but this approach is not as reliable and takes more time. Whole-house air sealing on auto-pilot When Eric was finished, he had a very tight house: 0.2 ach50, one third of the Passive House standard.

At least one type of caulk can be sprayed into wall, ceiling and floor assemblies to seal air leaks. Knauf’s EcoSeal is a water-based elastomeric that is applied with an airless sprayer. According to this article, Knauf developed the product to improve the performance of the air-permeable fiberglass insulation it sold. Once leaks in stud bays and other cavities have been sealed, and the spray-on material has cured, fiberglass batts or blown-in fiberglass can be added to complete the insulation. Insulation performance improves when it is completely enclosed in an airtight cavity. An air barrier can be located anywhere in the building assembly: on the outside of the building, the inside of the building, or in the middle of an exterior wall.Bogie has come to the same conclusion. “Canned spray foam is not a reliable air barrier for window and door rough openings,” he wrote in an article posted at GBA. “It can pull away from the framing or the window with seasonal wood movement and it is known to disintegrate over time.” Bogie, too, has switched to sealing tape. Air-sealing is a commitment
