Is insulation a heat source?
Insulation doesn't “heat” an area, it simply slows down heat movement through building materials. Since heat will always move to a colder source, in cold climates, insulation slows the heat from leaving the house and in hot climates insulation slows down the hot outside air from entering the cool inside.
What exactly is insulation?
Insulation will help you keep the desired temperature in your house all year round, protecting it against cold in winter and excess heat in summer. Insulation is also useful to reduce noise pollution. A well-insulated house is very energy efficient and will need very little additional heating and cooling.

What is insulation material?
Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Rigid foam boards trap air or another gas to resist heat flow. Highly reflective foils in radiant barriers and reflective insulation systems reflect radiant heat away from living spaces, making them particularly useful in cooling climates. Other less common materials such as cementitious and phenolic foams and vermiculite and perlite are also available.
What is cotton insulation made of?
Cotton insulation consists of 85% recycled cotton and 15% plastic fibers that have been treated with borate--the same flame retardant and insect/rodent repellent used in cellulose insulation. One product uses recycled blue jean manufacturing trim waste. As a result of its recycled content, this product uses minimal energy to manufacture. Cotton insulation is available in batts.
How does R value of polyurethane insulation change over time?
Like polyiso foam, the R-value of closed-cell polyurethane insulation can drop over time as some of the low-conductivity gas escapes and air replaces it in a phenomenon known as thermal drift or ageing. Most thermal drift occurs within the first two years after the insulation material is manufactured, after which the R-value remains unchanged unless the foam is damaged.
What happens to the R value of polyisocyanurate insulation?
Over time, the R-value of polyisocyanurate insulation can drop as some of the low-conductivity gas escapes and air replaces it -- a phenomenon is known as thermal drift or ageing. Experimental data indicates that most thermal drift occurs within the first two years after the insulation material is manufactured.
What is perlite made of?
Perlite consists of very small, lightweight pellets, which are made by heating rock pellets until they pop. This creates a type of loose-fill insulation made of pellets that can be poured into place or mixed with cement to create a lightweight, less heat-conductive concrete.
What is fiberglass insulation?
Fiberglass consists of extremely fine glass fibers and is one of the most ubiquitous insulation materials. It's commonly used in many different forms of insulation: blanket (batts and rolls), loose-fill, and is also available as rigid boards and duct insulation.
What is rock wool made of?
Rock wool, a man-made material consisting of natural minerals like basalt or diabase.
How does air insulating work?
Insulation works by slowing the transfer of heat, which can move in three ways: conduction, convection, and radiation.
How does insulation work on goose down?
Even though your jacket is light as a feather (more accurately, many thousands of feathers), your body can stay toasty warm. That's because the feathers create millions of tiny air pockets, and air has excellent insulating value - about R-7 per inch.
Why does compression compromise insulation?
Compression compromises insulation's effectiveness because it eliminates many of the tiny trapped air pockets that provide insulation value.
How does heat travel through down jackets?
For heat to travel from your body through your down jacket, it has to move by conduction through the tiny feather fibers that are in contact with each other. Heat transfer by convection happens through the air, and there are millions of minuscule air spaces between the fibers.
What is the R value of insulation?
A high R-value means greater resistance to heat flow and thus, greater insulating value. R-value is described both in R-value per inch and in total R- value.
Why is it important to air seal a section of your house?
This explains how important it is to air-seal a section of your house (such as the attic, basement or main living area) prior to adding more insulation. Moisture decreases R -value by making the insulation more conductive and by causing settling, compression, and voids.
Is it important to slow down the transfer of heat?
Slowing the transfer of heat is just as important in hot weather as it is during cold weather. So even though the down jacket example focuses on insulation's role in keeping a house warm in winter, the same principles apply when it's hot outside and you want to save money on air conditioning.
What is the job of insulation?
Insulation’s overall job is to resist heat flow in or out of a space. It keeps your warm house warm in the winter and your cool home cool in the summer. When thinking of traditional insulation – fiberglass and cellulose – think of it like the comparison of a wool sweater and a windbreaker.
What is the Process of Installing Spray Foam Insulation?

It All Begins with Your Morning Newspaper
Cellulose insulation starts with recycled paper from your community. When you are finished with paper products in your home and toss them in the recycling bin, that’s the first step to producing excellent quality insulation for homeowners across the United States.
Cellulose Insulation Helps Recycling Centers Become Profit Centers
When your recycled newspaper is received by the local recycling center, it is sorted and separated into different levels of quality. The best quality paper material is sorted out and marked for redistribution; pizza boxes and newspapers soaked with spilled coffee don’t make the cut.
The Recycled Material is Shipped to Manufacturers All Across America
American workers at regional cellulose insulation manufacturing facilities receive the recycled paper and load it onto a massive conveyor belt. This is where the real work begins. The paper moves along the conveyor belt and is shredded into small strips roughly three inches long.
