Why You Insulate

A picture before anything was done.
Spring day, sunny, but the air and soil aren't over 75. Inside temperature with the doors open - 115 at 6' high.

















During insulation process. Walls got about R20, with reflective barrior as well. Ceiling is at about R30, with reflective barrier. Soffit vents, peak vents (pre-existing).





















And after - much darker stain. Windows to let sunlight in for a greenhouse effect. Temperature today, 90, sunny. Open door. Temperature in 94 at 6' high.




To repeat - before, 75 and sunny with doors open - 115 at 6' high. After, 90 and sunny, doors open - 94 at 6' high.

This is why you insulate.


Insulation also prevents the depletion of our natural resources. Today's fiber glass insulation contains more than 25% recycled glass and uses renewable resources such as sand. In fact, according to the Glass Packaging Institute, Fiber glass insulation is the largest secondary market for recycled glass containers.
