It looks like good work but it would've been better if you would have used an environmentally friendly insulating material.

Greg- 
 
Thanks for the feedback. Actually, fiberglass is made from spun glass which is essentially sand - a natural material. Fiberglass and Cellulose each have their own positive qualities. That is why we install both. We present the facts of both materials and let the customer make the final call on the best material for their home. 

Sounds very cool, And wish fiberglass insulation will be perfect.

I have to say that, in my opinion, fiberglass insulation is old school. The most important thing to do when weatherizing a house is air-sealing. If you don't stop the movement of air the performance of fiberglass (and to a lesser extent cellulose) is substantially reduced. 
 
Sprayed foam is not subject to decreased r-value by this "wind washing" effect. When cellulose is installed dense-packed instead of just sprayed loose on an attic floor it is not really subjected to that effect either. 
 
Because air sealing is so critical, we always insulate the rafter slopes of attics- not the attic floor. It is much easier to properly air seal the slopes versus the floor and therefore this is MUCH more effective at reducing energy consumption, increasing comfort, and decreasing ice dams. In fact, because dense pack cellulose and spray foam are so effective, we can install them in roof slopes with no ventilation and not have to worry about ice dams.

Thanks for the thoughtful response Mark. I believe that insulation material is one subject that will be forever the great debate. Each material has its positive and negative properties as well as ideal application scenarios. It all comes down to what the customer is most comfortable with after the installer explains the pros and cons of each material.

You're right about that Damien. Keep up the good work!
