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!!!
This Ashburn, VA had rooms over the garage that were too hot in the summer. This is can often be caused by fiberglass batts installed by the builder in the ceiling of the garage. They fall away from the sub-flooring depleting all thermal insulating value. This customer decided to remove the entire garage ceiling and use closed cell spray foam to fix the problem.
Cold floors in rooms above garages are typically caused by air gaps between the sub-flooring above and the fiberglass batt insulation below. Any time insulation does NOT touch the surface you are trying to keep warm or cool...it will NOT work!
See how big the gap between the floor and the insulation is in this Sterling Virginian Home WOW!!!! This might have been the worst we have ever seen...Might be 2-3 feet of a gap!
Our team spray foamed the gaps to ensure no air leakage. These floors are now much more comfortable!
This Sterling, VA homeowner had a utility room that backed up to their garage. There was a lot of air leakage allowing cold air to travel through the utility room and into the basement making it cold in the winter.
Thermax foam boards and one part foam was used to seal this air leakage off, and to keep it safe from flammability. Thermax is a fire resistant material.
This Sterling, VA homeowner had a nice storage area beneath the stairwell that is adjacent to their garage. The cold garage air made this room very cold int he winter. Comfenergy used Thermax foam boards and two part foam to air seal it and make it warm to put to better use!
