The homeowner in Ashburn called, as last year their pipes froze and they did not want that to happy again.This home i has always had issues with hot and cold spots, and freezing pipes in the winter. We found cold air in the master bedroom attic to be getting around the batt insulation leading to the bathroom above. This entire neighborhood of as notorious drafts and hot/cold spots. These homes have also dealt with many frozen water lines. The water lines were freezing almost 20 feet from the exterior of the home! Comfenergy installed 4" thick SilverGlo foam boards with heat reflective barrier on the attic walls.
Problem solved!!! Foam board insulation in an attic keeps the cold air from travelling beneath the bathroom tub and the pipes from freezing.
The homeowner will be more comfortable in the Summer and Winter.....but it lessened the draftiness of the home, and the pipes don't freeze any more!!!
