Why Insulation Matters 

Undeniably, home insulation is one of the most effective ways to protect a home we all love to live in. It is a step towards saving energy and money. What’s more, insulation brings warmth, security from harsh weather and smile on our faces. Because of insulation, our homes are warmer in the winter and cooler in the summer. But with so many methods of insulation available, we here at Berks Insulation will guide you where to start.

In this blog post, we are going to let you know some of the secrets of Loose-Fill and Blown-in Insulation. But before, we jump to the main topic; it is unavoidable to be aware of how the heat transfer method works. Indeed, without understanding the heating system, we cannot learn how insulation exactly functions. As a result, we may not be able to apply loose-fill and blown in-insulation.

Heat Transfer Process

There are three main ingredients of heat transfer process.  These include conduction, convection, and radiation.

First, in conduction, heat travels through objects. The example of heat moving through conduction is a metal spoon left in hot coffee heating up.

Next, we have convection. Contrary to conduction, this circulates heat in liquids and gases. Without a doubt, this phenomenon leads to the formation of air layers in homes, where colder air settles at the bottom and warmer air rises to the top.

Lastly, there’s radiant heat. This travels in a straight line and increases the temperature of anything it comes across. An illustration of radiant heat is the warmth experienced by hot car windows on a summer day.

How Insulation Works

To start with, there are several types of common insulation materials that help keep home temperatures steady and reliable. These materials slow down conductive heat flow and, to some extent, cut down on convective heat within. Moving on, we’ve reflective barriers that don’t act as true insulations but work in tandem. They, in fact, fend off radiant heat, so they reduce the overall heat load that insulation has to deal with. 

So what’s the goal? Truly, primary goal is straightforward: retain cooler air in summer and warmer air in winter. This is where insulation comes into action, working to ward off external temperature influences.

What’s more, proper insulation doesn’t just shield. It actually resists the flow of heat. This is how it makes sure that you and your family stay happy throughout the year.

Heat Flow and Temperature Balance

First, heat naturally moves from warmer to cooler areas. It strives for equilibrium until temperature differences level out. As winter sets in, heat flows through air spaces and travels from room to room. Moreover, it potentially escapes to the attic or basement. It faces exposure to outdoor temperatures.

When the days are extremely hot in the summer, heat poses a challenge to the cooler indoor temperatures. Now it is time for insulation to step in. Upon its arrival, it slows down the exchange of air temperatures between inside and outside. Further, to ensure year-round comfort, it’s important to cut down on heat exchange. This is where insulation shows up again. It actively resists the flow of heat and ensures a steady environment.

Exploring Loose-Fill and Blown-In Insulation

To start with, in loose-fill insulation, we use small particles of fiber, foam, or other materials. These particles fit into any space without causing disruptions. Moreover, there are great for retrofits and tricky spots where other insulation types may be tough to install.

Now common materials include recycled cellulose, fiberglass, and mineral wool. Cellulose mainly comes from recycled newsprint.  While fiberglass often has recycled glass, mineral wool uses 75% recycled materials. Less common materials, like polystyrene beads and perlite, are also used. You can install it on your walls or attics. Pros use a machine for cellulose, fiberglass, and rock wool. For polystyrene beads, vermiculite, and perlite, they simply scatter them.

Importance of R-Value in Insulation

The Federal Trade Commission enforces a rule about labeling and advertising insulation. This rule ensures manufacturers and sellers disclose product details, like R-value, on labels and fact sheets.

For loose-fill insulation, manufacturers must figure out R-values at settled density and provide coverage charts. These charts show settled thickness, weight per square foot, and coverage area per bag for different R-values.

On the other hand, thicker stuff gets heavier when squished. This truly affects its warmth. So, charts help know how much stuff to use for certain warmth levels. They show the most and least weight needed.


Unquestionably, the best type of insulation for your home depends on your budget, the climate you live in, and the type of home you have. Moreover, installing the correct insulation is highly important. Because without it, you’ll end up facing problems caused by air leaks. In other words, there will be heat accompanied by cold air in your home.  You and your family will suffer a lot. So, always be careful when installing either loose-fill insulation or blown insulation.
