Living Green in Colorado: Air Sealing Materials

if you’re considering some do-it-yourself weatherization projects, make sure you’re using the right air-sealing materials for the job:
Caulk — Seals gaps of less than ½ inch. Select grade (interior, exterior, high temperature) based on application
Spray foam,— Fills large cracks and small holes. It can be messy (use light weigh disposable latex gloves. If you do get some on your hands you can use kerosene or rubbing alcohol to remove the foam from your hands) consider new latex-based foams. Do not us near flammable, applications (e.g., flue vents). ho not use expanding types on windows and doors
Backer rod — Closed-cell foam or rope caulk. Press into crack or gap with screwdriver or -putty knife. Often used with caulk around window and door rough openings
Housewrap — Installed over exterior sheathing. Must be sealed with housewrap tape or caulk to form an airtight seal. Resists water but is not a vapor barrier. (Mainly used in unfinished crawl spaces)

1. Weatherize your home and save up to 10% of your heating and cooling costs. A handy homeowner can seal up holes to the outside by weather-stripping doors and window, and sealing windows and gaps along the home’s foundation.
2. Set your thermostat to 68°. Your heating system will operate less and use less energy. Turn your thermostat down 5°at night or when leaving your home for an hour or more to save up to $70 on energy costs each year.
3. Install low-flow showerheads and faucets. It really helps! 1.8-gallon per minute showerheads can reduce your hot water consumption by as much as 10%. You’ll see savings up to $6 per year for a sink faucet aerator and $30 per year for a showerhead.
4. Switch to compact fluorescent light (CFL) bulbs. They cost a little more, but you can save about $50 over the life of just one bulb.
