R-Value – Thermal Resistance in Spray Foams

The value should be your guide when installing insulation and foam. But, it should not be the only method to measure insulation because heat loss can happen in several ways. The six methods you can apply to determine heat losses include the following:

Heat Loss Mechanisms To Prevent

  • Conduction
  • Radiation
  • Convection
  • Air infiltration
  • Moisture accumulation
  • Air intrusion

Spray polyurethane foam is effective in preventing the six types of heat losses. The six heat transfer methods should form a mechanism for you to choose the best insulation. You can as well use Energy star map to choose the best insulation in the United States.

Last Minute Insulation Tips

In average, the price of a sheet which can cover 200 square feet is between $250 and $500. This is about two or three kits. The kits contain icynene which is a foam made out of liquids. You will have to spray on the surface you intend to insulate, and it will expand for up to 100 times. Gases produced are poisonous hence you should take necessary precautions.

It is hard for someone unexpected to apply it perfectly. Leaving small holes due to the uneven application can leave spaces for cold air to enter the building. You should do it yourself if you are applying in small areas. You can do areas around crawl space or plumbing lines, but let experts work on larger projects such as the attic, garage, and basement. Professionals will apply the right tools, and they have the necessary knowledge.
