Home Improvement Glossary: I
ice dam: Ice dams are blockages that can develop on a roof that isn't well-insulated. When the snow on the roof melts, the water runs down and freezes over the eaves, causing water to back up behind the ice and under the roofing shingles.
infrared sensors: Infrared sensors are electronic devices that measure the infrared light and are often used in motion sensing security devices.
intake valve: The intake valve controls the amount of water that enters the toilet tank.
