Common Misconceptions about Sol-Blanket Insulation™

Sol-Blanket Insulation™ is a versatile product that can be installed in many places within a home or office building.  Unlike traditional insulation which prevents convective and conductive heat transfer, Sol-Blanket Insulation™ works primarily against radiant heat transfer, stopping its transfer into and out of the home.  Sol-Blanket Insulation™ works effectively as part of a whole attic system that includes traditional insulation along with proper ventilation and sealing.   The result for customers is reduced energy consumption, lower energy costs, and increased comfort in their home or business.  With that said, there are some common misconceptions about Sol-Blanket Insulation™ that need to be addressed.   First let’s describe the makeup of Sol-Blanket Insulation™ and how it works.


What is Sol-Blanket Insulation™ and how does it work?


Sol-Blanket Insulation™ works as a radiant barrier or reflective insulation.  It has five layers and is ⅛ of an inch thick.  The defining element of Sol-Blanket Insulation™ is that it reflects heat back to the source rather than absorbing it.  Sol-Blanket

Insulation™ is perforated to allow minute amounts of moisture to pass through it, thereby helping to prevent mold, mildew and rot from forming in the attic.   Sol-Blanket Insulation™ is usually installed horizontally over existing insulation on the attic floor or attached to joists in the crawl space of a home.


Misconception #1 – Sol-Blanket Insulation™ is not very thick so it can’t block much heat


There are three kinds of heat transfer.  Conductive, convective and radiant.  All insulation is given an R-value based on its thermal resistance.  Thermal resistance refers to conductive and convective heat transfer.  Some materials carry a higher or lower R-value than others based on the makeup of the material and it’s application.  R-value can vary from home to home based on the direction of heat flow and the amount of air space in a closed cavity on the reflective side of the product in a building assemblage.  The air in the cavity actually acts as a form of insulation preventing convective and conductive heat transfer.  That’s a really technical way of saying it’s not size that matters!  Remember Sol-Blanket Insulation™ reflects rather than absorbs radiant energy.

 Sol-Blanket Insulation™ uses a closed-cell polyethylene foam core.  In and of itself it has a very low R-value.  However, as described above, R-value doesn’t just depend upon material – but also application.  Smart Energy Today performs a free in-home analysis for any prospective customers where they can discuss application and expectation of results from Sol-Blanket Insulation ™.


 Misconception #2 – Sol-Blanket Insulation™ only works in hot regions – not in colder climates


Sol-Blanket Insulation™ reflects radiant energy back to the source regardless of the direction of heat flow and regardless of the outside temperature.  While the summer months will see the most benefit from Sol-Blanket Insulation™, it works very effectively in maintaining a comfortable temperature in the winter as well.


To illustrate how Sol-Blanket Insulation™ works in the winter think of a baked potato.  Most people wrap them in foil to trap heat.  Some people do it just because mom did!  In any case, the reflective nature of the foil reflects back the heat trying to escape the potato, thus keeping the potato warm for a longer period of time.  That’s why mom probably did it!


In the winter Sol-Blanket Insulation™ works the same way.  As heat rises and seeks to escape the home through the ceiling, the Sol-Blanket Insulation™ reflects the heat back into the home keeping it warm for a longer period of time.

Misconception #3 – Sol-Blanket Insulation™ works like an air conditioner to make your home cooler in the summer or like a heater to make the home warmer in the winter


Reflective insulation and radiant barriers reflect radiant energy.  They do not produce energy – hot or cold.  The second law of thermodynamics says that heat always moves towards cold.  In the summer this means that radiant energy from the sun is trying to get inside your home where it is cooler.  In the winter the heat from inside your home is trying to escape the home and get to the cold outside.  In both cases Sol-Blanket Insulation™ acts as a barrier and reflects the radiant energy back towards the source.


Misconception #4 – Sol-Blanket Insulation™ installed in my crawl space will keep my floor warm


Depending on the climate or region you live in Sol-Blanket Insulation™ may have a slight one to two degree effect on your floor temperature.  It will likely take the “chill” off the floor if you have a tile or hardwood floor.  Remember, Sol-Blanket Insulation™ is not a heater!  It reflects radiant energy.  If you live in a cold climate that means it will reflect the small amount of heat moving towards the cold floor (from within the home) back into the home.


Misconception #5 – Sol-Blanket Insulation™ prevents pest and rodents problems in the attic or crawl space


Sol Blanket Insulation™ is made of materials that pests and rodents don’t like.  The majority of the time Sol-Blanket Insulation™ is installed over existing insulation.  This means that pests and rodents would first need to chew through the Sol-Blanket Insulation™ which would be very undesirable for them.  Chewing on the materials that make up the Sol-Blanket Insulation™ for a pest or rodent is much like a human running their nails across a chalkboard.  With that said installing the Sol-Blanket Insulation™ over existing insulation acts as a deterrent and doesn’t replace the need for an exterminator.  Pests and rodents are crafty!


Misconception #6 – Sol-Blanket Insulation™ should be installed on rafters inside the attic below the roof-line

In some climates this makes sense, but installing Sol-Blanket Insulation™ on the rafters in the attic means that in the winter the attic will get heated!  The cost of heating the attic adds up over time and Smart Energy Today, Inc. ™ focuses on comfort inside the home.


During the summer when it gets really hot some people may be worried about the adverse effects the heat in the attic can have on the structure of the roof.  Smart Energy Today, Inc. ™ recognizes this and educates customers around proper attic ventilation.  The company also offers a solution – a solar attic fan!  Proper ventilation will ensure heat does not get too extreme in the attic.


 Misconception #7 – Sol-Blanket Insulation™ needs to be installed in the ceiling over the garage


One way Sol-Blanket Insulation™ can be used in the garage

The garage portion of a home is typically not insulated.  You are not producing heat or cold in that area of the home.  Therefore, if heat pushes into the garage from the attic – it’s no big deal!

Some people spend a lot of time in the garage – maybe they use it as a home office.  If that is the case and you do spend a lot of time in the garage, then installing both insulation and a radiant barrier makes sense in order to prevent heat gain or heat loss when it is undesired!


Misconception #8 – Sol-Blanket Insulation™ should be taped or stapled together at the seams


Sol-Blanket Insulation™ does not need to be taped or stapled at the seam to work.  Gravity works just fine!  It doesn’t need to be perfectly sealed.  You actually want a minute amount of air (moisture travels through air in the form of vapor) to escape.  You want it to “breathe”.  This will hinder moisture build-up and keep mold and mildew from occurring in existing insulation or rotting the structure of the home.  With proper caulking and sealing as well as ventilation simply laying the Sol Blanket Insulation™ over the existing insulation works effectively.
