SEALECTION 500 is a relatively new product in the home-insulation market with many added benefits over
standard fiberglass batts insulation. The greatest benefits of SEALECTION 500 are in its thermal resistance performance
and low air leakage. The R-value of a wall using fiberglass batts insulation can be significantly reduced from the laboratory
measured R-value as a result of air leakage through the wall. The R-value of a wall using SEALECTION 500 however,
suffers NO reduction in its R-value because Sealection 500 minimizes air leakage.
Most factory-made insulation materials suffer a reduction in performance due to air leakage. As a result,
the insulating value of many walls may be as low as 50% of the R-value of the insulating material they contain. By contrast,
the insulation value of a wall containing custom-installed SEALECTION 500 performs close to the laboratory tested
R-value of the material and seals the wall cavity from air filtration as well.
SEALECTION 500 is custom installed and expands after spraying. It can completely fill any cavity
and form a continuous air barrier by adhering to other building materials. These are things that batts and boards and blown
insulation simply cannot achieve, which accounts for the superiority of the SEALECTION 500 system. Think about it:
every gap or void in normal insulation has an R-value of nearly zero. That's not a problem with a house insulated with SEALECTION
500.
In conclusion, SEALECTION 500 differentiates its nominal R-value from fiberglass basically showing
that R-values are not created equal ; there are laboratory R-values and performing R-values.
