The experts on home improvement shows make it look easy, but installing insulation yourself can be messy, tiring and, if you don't plan carefully, as expensive as hiring a professional.
You can do it yourself if: - You've identified the type and amount of insulation you currently have.
- You can purchase the additional insulation from a reputable retailer with a knowledgeable staff.
- You've successfully tackled other home improvement projects.
- The area is accessible and easy to maneuver in, and has few obstructions.
- No structural changes are involved.
- The existing insulation is dry and properly installed.
- Your roof is in good shape.
The number one rule (as always) is to follow the manufacturer's instructions exactly.
Skipping steps and taking shortcuts could mean significant reductions in R-value - and a waste of your money and effort. Allow yourself plenty of time and make sure you have enough materials to complete the job.
A few more tips to keep in mind: - If you choose fiberglass insulation, the new "no-itch" products are worth the extra cost. They're much easier to handle and safer to work with.
- Always wear goggles, a dust mask or respirator, gloves, long sleeves and long pants when working with insulation. For the best protection, wear a hat, tuck your sleeves into your gloves, and tuck your pant legs into your socks.
- Be very careful moving around in your attic. Watch out for overhead rafters, and walk only on ceiling joists. If you have room, lay a plywood panel across the ceiling joists to walk or kneel on.
- Avoid disturbing existing insulation - especially loose-fill. Moving it around can create gaps where air can leak through.
- When adding batts or blankets, install them at right angles to the first layer.
- Never put insulation over recessed light fixtures, ceiling fans or ventilation fans. If you're using loose-fill insulation, use sheet metal to create barriers around the openings. Keep all insulation at least three inches away from chimneys and gas flue pipes.
- Make sure to allow for adequate ventilation. Never cover attic vents, and leave at least one inch of air flow between the insulation and the roof.
- Don't forget to insulate and weatherstrip the attic opening.
