For this project contractor requested 6 inches of close cell foam in ceiling, we used Huntsman Close Cell foam that provides a Rvalue of 7.4 per inch. 

For the walls we used Huntsman Open cell foam to provide a R19

For this project the contractor requested Rockwool mineral wool in all open walls and interior ceilings. For the flat roof the homeowner requested that we use Owen Corning Natural Polymer close cell foam in flat roof.

Contractor contacted us about a small office addition. Plans required R21 insulation and R30 insulation in roof. For the vaulted ceiling since there was no ventilation we used Huntsman Agribalance open cell foam to achieve the R30, for the walls we used Owen Corning R21 fiberglass batt insulation. Helped the contractor save money by suggestin agribalance instead of using close cell foam.

Project in Castro Valley, plans required R15 insulation in walls and R30 in ceiling. contractor asked for the R15 to have the kraft facing.
