to pay close attention to the indi- cations on the packaging, making sure they match the job at hand. Whether the product is flexible, waterproof, paintable, or contains a mildewcide additive, all features should be listed prominently on the label, and you generally get what you pay for. Another popular sealant is spray-in expandable foam, which comes in an aerosol can. It’s important to select the right insu- lating foam for the job; too much expansion in the wrong place can put unwanted stress on the con- struction. Use the “no warp” for- mula of expandable foam around windows and doors. SEAL LEAKS BETWEEN MOVING PARTS OF THE HOME WITH VARIOUS TYPES OF WEATHER- STRIPPING Compression Strips include open and closed-cell foam or rubber tapes, as well as tubular strips. The open-cell tape will give you a quick fix until you can properly measure and fit a permanent solution. Closed-cell tapes allow you to correctly size the gap you are working with and are more durable for doors and windows that are used often. Use where there is a pressure stress: along the bottom of verti- cal sliding windows, around attic
Thresholds attach to the floor to seal the gap beneath a door and some can fill a gap up to 1-3/8″.
