How much do ‘U-Value’ good thermal insulation? Part V

Posted Mar 2, 2010, by Robin Bornoff

Why is it that when you increase a cavity air gap size beyond ~30mm is there no subsequent detrimental affect on the overall U-Value? Why is it that the U-Value of the cavity gap nearly doubles when the air gap reduces to such as size so as to stagnate the air? Questions that come begging after observing the FloVENT simulation results discussed in the previous blog posting. Let’s find out…. When I … Read More
