Ceilume’s vinyl ceiling tiles (ceilume.com) look like tin or plaster, but at just $1 to $2 a square foot, they cost a heck of lot less. They come in 32 styles and eight colors, are lightweight, and are easy to install in suspended or direct-mount ceilings. They’re great in kitchens and bathrooms because moisture doesn’t affect them, and they’re easy to clean. The tiles are eco-friendly, too: they’re GreenGuard-certified for indoor air quality, and do not harbor dust, mold, mildew, bacteria, or odors.
