Insulating Exterior Walls : Insulating Interior Walls : Attic Space Insulation

The Attic Space
More insulation can be added in your attic space by simply blowing additional insulation on top of the existing blown or batt insulation. The increase in R-value is determined by the depth of the finished product.

Drywalled Exterior/Interior Walls
Many older homes have little or no insulation in the exterior or interior walls. We do not provide insulation service for sheet-rocked walls where holes would need to be drilled and the wall-space filled with blown insulation.

Home Additions
Adding one or more rooms to your existing house will call for insulation in the exterior walls and interior walls (for sound-reduction, if you choose). The R-value will be based on the size of the studs in the wall-space. You may choose the R-value that is per code of the county in which you live (the minimum thickness), or upgrade the insulation thickness (increases the R-value), to what the wall-space will allow. Discuss this with your contractor.
