Incandescent, CFL, LED Lighting ‘Cost Over Life’ Comparison

Spray foam insulation conserves energyWhen it comes to home energy efficiency, spray foam insulation is a wonderful alternative to traditional insulations like fiberglass. Did you know that 40% of your homes energy is lost due to air infiltration according to the United States Department of Energy!? The spray polyurethane or polyisocyanurate foam insulation is traditionally applied as a liquid from a spray foam gun. As it is sprayed, the foam insulation rapidly expands and cures to fill cavities in walls, roofs and even drilled holes or other openings which may cause heat to disperse or drafts. This method is a very safe to way to insulate your attic or your walls during construction or remodeling.

Types of SPF

There are two types of spray foam insulation, open cell and closed cell. Installation cost is the major factor in deciding which spray foam is right for most homeowners. Open cell is significantly cheaper than closed cell and provides very good R-value to your house. The benefits for both include:

Open Cell Spray Foam (SPF) Benefits

  • Typical R-value of 3-4 exceeds fiberglass (2.5 +/-)
  • Unlike fiberglass, completely blocks air flow to prevent energy loss
  • Provides acoustic insulation also
  • Expands into many little nooks and crannies fiberglass can’t
  • Can be installed in existing walls without tearing out

Closed Cell Spray Foam (SPF) Benefits

  • Typical R-value of 6-8 drastically exceeds open cell & fiberglass
  • Completely blocks air flow and is non-porous so liquids and moisture cannot get penetrate
  • Mitigates mold and mildew since moist air cannot penetrate its membrane
  • Provides acoustic insulation
  • Expands into many little nooks and crannies fiberglass can’t
  • Can be installed in existing walls without tearing out
  • Great product for tight or narrow spaces requiring insulation
  • Can be installed with little to no waste material, highly efficient
  • Reinforces the structural strength and integrity of your home

Additional Benefits of SPF

It is very important for both saving money and personal comfort to properly insulate your home. Spray foam insulation provides the protection that your home and belongings need. Just think of the long term benefits of reduced energy costs, especially as energy prices continue to grow! In the winters you will prevent heat loss, depend on your heating system less, and minimize the strain on your air conditioner during the dog days of summer. This will extend the life of your units, just another added benefit of spray foam insulation. Another positive of spray foam insulation is that it will help protect the wood structure of your house from moisture and insect damage. Best of all, the US government offers a tax deduction for homes which utilize spray foam insulation.
