Attic Kneewall Old Insulation in Holmdel, NJ

Here in Holmdel, NJ, we removed the old fiberglass insulation because fiberglass does not stop the air flow, and does next to nothing to air seal and insulate. The floor of the upper level, the ceiling of the lower level and kneewall are all cold in the winter and hot in the summer. Installing our SilverGlo foam insulation onto the attic walls increases the R-value by 24% compared to regular EPS foam. Our SilverGlo also acts as a radiant barrier on both sides to reflect heat out of the summer and house heat back in during the winter. We also sealed the seams of our SilverGlo foam insulation with orange ZypFoam sealant to ensure the best protection from hot or cold air and unwanted moisture.

The before image shows old fiberglass insulation and unwanted air being ventilated through the insulation by leaving dirt or dust particles onto the insulation. The older fiberglass insulation does nothing to stop cold and hot air from penetrating the rooms below or next to the kneewall.

The after image shows the completed SilverGlo foam insulation installed onto the kneewall. The image is still in the process of installing the Blown-in TruSoft Cellulose insulation. We can also see we used the orange ZypFoam sealant to seal the seams.
