​How Insulation works

CALL US 248-487-8832
Heat transmission, R-value, and placement are the three key factors that influence how insulation works. To keep your room comfortable, your HVAC system must restore the heat gained in the summer and lost in the winter. Heat resistance occurs when a space is properly insulated, which reduces the heat flow process and helps your space to maintain a comfortable, consistent temperature.

​Insulation Operates by Transferring Heat

The second rule of thermodynamics must be understood in order to comprehend heat transport and how insulation impacts it. Nature has a tendency to balance and equalize various energy levels. Heat and energy are notions that go hand in hand. Each atom, the building block of the universe, has a specific quantity of energy inside it at any given time. As a result, it may also be claimed that these atoms and the things they form hold various amounts of heat.

Two items are used in a straightforward illustration: your stove and a pot of water. The second rule of thermodynamics, which states that heat passes from an item of higher temperature to one of lower temperature, explains why a hot burner eventually causes the pot and its water to warm up as well. This law is in operation even when there isn't any heat as we often understand it. Even at a millionth of a degree above the freezing point, a block of ice will inevitably melt. Even though this energy transfer is inevitable, the rate at which the temperature changes relies on factors including the materials the heat must pass through and the kind of heat transfer—conduction, convection, or radiation.

​R-Value: An Overview

The ability of a substance to withstand temperature variations can be measured by its R-value, much like how we estimate the amount of energy (heat) in an object by evaluating its temperature. The phrase is related to thermal resistance. An R-value rating, which indicates how well commercial insulating materials like cellulose, fiberglass, and spray foam inhibit heat transfer, is given after testing. The better a substance insulates, the higher its R-value. R-value, in more scientific terms, is a measurement of thermal resistance per inch used to compare materials "apples to apples". A one-inch cube of a material with an R-7 rating can insulate twice as well as one with an R-3.5 rating. An R-value graded substance can have many units. For example, an R-4 layer six inches thick would be rated R-24.

R-value is significant, however doubling the insulation's R-value won't increase a building's resistance to heat input or loss. Doors, windows, studs, and air leakage are some of the aggravating elements. Regardless of the R-value of your insulation, temperature change (and moisture along with it, but that's another subject entirely) still occurs due to air movement or conduction in the materials of walls, windows, doors, and other building components. R-value is merely one aspect of performance as a whole. We'll talk more about how sealing can significantly improve a building's energy efficiency later.

​Finding The Ideal Location

Depending on where and how it is installed, insulation may or may not be able to block heat flow. Insulation that has been squeezed, for example, loses some of its predicted R-value. Like weight, R-value can also be a cumulative measurement. Similar to how the weight of fifty persons is different from the weight of each one while still being measured in the same units, the R-value of an attic, wall, or crawlspace is distinct from the insulation itself (pounds). The R-value of the insulation has a base value, and the R-value of an assembly of insulation is based on the thickness and density of the insulation in a particular area.
