  • Moisture and Fiberglass Insulation in Metal and Steel Buildings

    Several of our last posts have dealt with your outbuildings. Metal and steel buildings are excellent choices for affordability and low maintenance. These buildings are for the most part worry free structures. For owners who want full use of their buildings in all seasons, insulation becomes important. As condensation and moisture are always an issue, understanding your insulation is always important. Here's a link to facts about moisture and fiberglass insulation for metal buildings offered by the North American Insulation Manufacturer's Association that is comprised of the four largest fiberglass manufacturers in the United States.

  • Radiant Barrier Insulation: Some History and Useful Information

    This post describes how radiant barrier technology was created by NASA and its use in home insulation.
  • Insulation & Understanding Heat Transfer in the Home

    Many consumers don't really understand how heat transfer works and more specifically how it pertains to their home. A better understanding will certainly help in using the correct materials to lower energy costs. This short post helps to explain this.
  • Fiberglass R-Values and Staple Tab Foil Insulation

    Fiberglass insulation comes in a variety of thicknesses. We supply a line of radiant barrier insulation that sized to fit the same applications to be installed with or without fiberglass. This short post explains more.
  • Insulating Walls with Reflective Foil Bubble Insulation

    Are you interested in seeing how to insulate your walls with reflective insulation? Take a look at this video to see one of the three installation methods. This method is the fastest and least time consuming. In order to finish the wall with drywall or any finishing material you will need to add furring strips to keep an airspace. The other 2 methods (not shown on this video) incorporate an airspace in the installation process. Visit us at

  • Radiant Barrier Insulation and Stopping Attic Heat Gain

    What actually happens in your attic and how are radiant barriers effective?

    To answer this question we need to look at how your attic works in the form of heat transfer.

    As the heat from the sun warms your roof deck, this heat is passed through the roof into the roofing materials and into your attic. This is conductive heat transfer. From here, this heat is radiated through the attic warming everything it contacts. This is radiant heat transfer. As the radiant heat contacts the fiberglass insulation, it converts to conductive heat transfer again and warms the fiberglass insulation and your ceiling below and into your cooler living space.

    The warmer the attic space, the more heat is transferred into your living space. If your attic temperature is 140 degrees which is common in summer months, this 140 degree heat is constantly robbing your cooler inside air.

    You cannot stop attic heat gain but there are three options that you can do to lessen this heat transfer, thereby saving you money.

    1. Increase attic ventilation: If you do not have enough attic ventilation there is nowhere for the climbing heat to flow and your attic will heat up much quicker than if you had appropriate ventilation. Add louvers, passive attic fans, or soffits and ridge vents to correct this problem.
    2. Increase the amount of fiberglass insulation: Few homes are built today and none were built yesterday with the correct amount of fiberglass insulation. Contact your local building department for recommended thicknesses. If adding fiberglass in batt form, make sure to run the batts perpendicular to the original insulation. As the radiant heat that permeated the attic contacts the insulation, there is more resistance or R-value to slow the now conductive heat buildup.
    3. Add a radiant barrier: Radiant barriers naturally reflect 96% of radiant heat. The addition of foil insulation will lower your attic temperature. Radiant heat that before passed through the roof deck and onto the fiberglass insulation is reflected back out of the roof deck and away from the home. Using the same example from above, now your attic temperature with a radiant barrier is 110 degrees. Now only 110 degree heat is constantly robbing your cooler inside air. This 30 degree temperature difference results in much less attic heat transfer and saves you energy.

    This is exactly how radiant barriers work in the form of attic insulation in warm months and are effective at lowering your utility costs. Used in conjunction with correct ventilation and correct fiberglass insulation levels, you can be sure you have the most energy efficient attic possible.
