The hidden elephant in your cold room may be air leaks.  It is not just cold air coming in, but also warm air escaping in the upper half of your home or building.  A typical older two-story house has enough air leakage to equal a wide open gap 25 inches wide and 12 inches high!

We all need to breath, but most buildings have way too much fresh air flowing through their living space.   Outside-inside temperature differentials, wind speed, and room location can also affect how much outside air flows through a building.

Take control of your fresh air needs by controlling air leakage and installing an appropriate ventilation system.  Building Energy Technologies offers both expert air leakage sealing and affordable powered ventilation solutions.   

A blower door test is the only way to accurately diagnose air leakage.
