Starting today I thought it might be a good idea to take a look at Energy Consumption in your new home. Vermont Modular thinks it is environmentally the correct thing to build a home that consumes as little energy as possible! The constant burning of fossil fuels continues to severely harm our environment and each of us can make a difference by consuming less energy in our home. We can accomplish that by either being uncomfortably chilly throughout the winter or I'm suggesting that we build for you The Most Energy Efficient Home in Vermont. Yes, that is what we consistently advertise and we are committed to our mission of building energy efficient homes, it's what we do.
Building an energy efficient home is the melding of several systems into one unit. The simplistic approach of just doing one thing will not achieve energy efficiency. So having said that over the next several days we will address various aspects of the component parts of an energy efficient home. We hope you will find that Vermont Modular goes to significant lengths to create systems that are not common practice construction techniques. We go out of our way to significantly strengthen the building envelope of your new home so that it is truly The Most Energy Efficient Home in Vermont.
Common practice in Vermont is to build the exterior walls using 2x6" lumber creating an insulation cavity of 5½" that is filled with Fiberglass Batt Insulation. Batt Insulation is the "Pink Stuff" that is widely used throughout the Northeast. The most current "Pink Stuff" has an R-Value of R-21. R-Values are the measure of Resistance provided to escaping heat. So, the higher the number the better the insulating capabilities and the less heat you loose.
Pink Fiberglass insulation has several Pros and Cons:
- Pros -
- Fiberglass insulation is relatively inexpensive and relatively easy to install
- Fiberglass insulation has become an industry standard and is widely used
- Cons -
- The Pink Stuff has limits on its insulating capabilities, in a 2x6" wall that is R-21
- The R-Value assumes that is it PERFECTLY installed and honestly that never happens, there are always gaps here and there allowing heat to escape
Vermont Modular does NOT build our exterior walls using the Common Practice techniques of 2x6" wall. We build a Double Wall that uses a 2x10" top and bottom plate creating a 9½" cavity for insulation. Once we have built the 9½" cavity we then fill that cavity using Blown In Fiberglass or BIB's insulation. This is NOT fiberglass Batts! The BIB's uses a pulverized type of fiberglass that is then blown into the cavity filling all the nooks and crannies with insulation so that everything is sealed shut. You will loose less heat. Further, using our BIB's concept the R-Value of your exterior wall jumps from R-21 all the way up to R-39.5 That is a HUGE increase in efficiency of 53%.
The Pink Stuff has an R-Value of 3.81 per inch. BIB's has an R-Value of 4.15 per inch. Further, when The Pink Stuff is compressed it looses some of its R-Value whereas when BIB's is compressed its R-value goes up.
Vermont Modular does not build using common practice techniques, we do much better and we'd love to show it all to you. The more informed you are the better a home you will have.
Enjoy a beautiful day.
I can hear people asking, "...why do they build using a double 2x4" wall?" The answer is easy to explain. Lumber is a very good conductor of heat in the exact same way your kitchen pots and pans mostly are made from Aluminum. Aluminum is a great conductor of heat so it spreads the heat around the pot or pan and helps with the cooking. Lumber also is a good conductor of heat but it now is transferring the warm air inside to the exterior of the home; hence it is a source of heat loss. So, Vermont Modular uses a double 2x4" wall where neither of the 2x4's touch each other, we create a Thermal Break and save you heat. The 2x6 lumber acts as a Thermal Bridge. Our double wall construction acts as a Thermal Break. The difference is truly significant.
