Achieving Greater R-Values in Attics
Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic, walls, floor and crawlspaces. These R-Values are a sum, meaning this should be the total R-Value once you add up the entire depth of new or existing insulation plus the Solaro Shield’s R-Value of R-17.9. For example, if you have a type of insulation that has an R-Value of R-15 per inch of thickness, by adding the Solaro Shield’s R-17.9 in your attic you will reach an R -Value of R-32.9, for homes in Zones 1,2 or 3.
Note from this chart that the ideal R-Value differs for each part of your home. The ideal attic insulation R-Value is different than the ideal wall insulation R-Value. Make sure your home is properly insulated in all these locations.
Insulation ratings can be improved by adding more layers of insulation. You can mix the type and material of insulation too. For example, if your attic already has fiberglass insulation blankets installed, you can improve its R-Value by installing Solaro Shield Blown-In Insulation on top of the blankets. The R-Values of both insulations will accumulate. You can Achieve better thermal performance in your attic by adding an additional layer of insulation.
Achieving Greater R-Value in Exterior Walls
As with attics or anywhere else in your home, adding more layers of insulation to your exterior walls is key to having a higher R-Value and better thermal performance. Solaro Shield Multi-Layered Reflective Insulation is easy to install over existing blanket insulation. Seal gaps around windows and doors with spray foam insulation
