Radiant Barriers and Their Affect on Your Cell Signal

As many homeowners know the cost of cooling and heating homes can often be one of the biggest expenses of owning a home. It’s no surprise that one of the biggest investments many owners make is often in insulation in an attempt to both keep the costs down and also make their homes more livable.  One recent trend in insulation is the radiant barrier. These are often quite a low cost and very efficient solution to reducing your energy bill.

How Does a Radiant Barrier Work?

A radiant barrier is a type of insulation that works by reflecting the heat radiation from your roof. This can be accomplished either with a spray on paint that sits below roofing. While this can be easier to install they typically are less effective than their foil counterparts. Also, these sprays interfere with your cell phone signal much less as well.

The foil radiant barriers are just what they sound like. They are a thin layer of foil that is installed in your attic under your roof. When installed you leave a small air pocket between the foil and the roof and the foil is able to reflect the heat, sometimes up to 95% of it, back outside instead of letting it come into your home. Unfortunately, this means they are much better at blocking your cell signal from coming in through your roof as well.

The effectiveness of a radiant barrier almost always relies on the installation. It is important for achieving the maximum effect to either hire a professional installation expert or too very carefully follow the manufacturer instructions and study the fire and building codes in your area.

How Does a Radiant Barrier Affect Cell Signal?

Because your cell phone communicates using radio waves it can be reflected by a radiant barrier similarly to how it blocks heat radiation. Both are types of energy being transferred in waves. It is often most pronounced in homes that already were receiving a weak signal.

While this does not occur in every home with a radiant barrier installed it is important to consider, especially if you already have a weak cell signal.

Other Forms of Insulation that Block Cell Signal

Other forms of new building materials are also doing many great things to help with rising electric and gas costs that are also hurting peoples pockets when they get their utility bill.

One of these new common solutions is low E glass. Low E or emissivity glass has an internal coating of an extremely tiny film of reflective coating that prevents heat from entering the interior layer of glass. This prevents the coating from both scratching off or becoming dirty and less effective.

Low e glass reduces the amount of heat that comes into a home but also the amount of cell signal.

As you can see in the image above the low E glass is able block heat from coming in during the summer and leave during the winter. Unfortunately, much like a radiant barrier it does the same with cell phone signal as well.

If you installed a radiant barrier, low E glass or some other form and noticed that your signal worsened HiBoost can help with one of our signal boosters. We will be able to improve your signal, possibly to more than you had before the barrier was installed in the first place. Our home booster solutions are perfect for boosting service to homes that recently installed a radiant barrier or low E glass and need their cell phone signal boosted because of them.
