With the rising awareness of environmental concerns and the need to reduce energy consumption, home insulation has become an increasingly important aspect of modern living. According to the U.S. Department of Energy, heating and cooling account for around 50-70% of the energy used in an average American home. However, proper insulation can significantly reduce this energy consumption by minimizing heat transfer and maintaining a comfortable indoor temperature, regardless of the outside weather.

Home insulation is much more than just a layer between your walls; it’s a strategic investment that pays dividends in the form of energy savings and enhanced comfort.

But if you’re not sure what kind of insulation you need, how much, or whether it’s worth hiring a professional to install it for you—or if there are other steps involved—you’re probably feeling pretty overwhelmed.

We get it. Home insulation is complicated stuff! That’s why we’ve put together this blog.

In this blog, Home Insulation Contractor in Phoenix will take you on a journey through the ins and outs of insulation, covering various types of insulation, how they work, factors to consider when choosing the right one for your home, and when it’s best to seek the expertise of a Phoenix professional.

Let’s dive in and explore the world of home insulation together!

What is Home Insulation?

Home insulation is a material that provides resistance to heat flow. Insulation helps to keep your home comfortable at all times of the year. It reduces sound and prevents drafts from coming through cracks or holes in your walls, floors, or ceilings.

Insulation materials can be made from various types of materials, including glass fibers, mineral wool, polystyrene foam, cellulose fibers, and others.

Insulation is commonly used in construction and home improvement projects to help reduce energy costs and improve energy efficiency. Insulation materials are often made from plastics such as polyurethane and polystyrene foam that provide excellent thermal resistance but can deteriorate over time if exposed to moisture or water.

How Home Insulation Works?

Home insulation works by creating a thermal barrier that limits the transfer of heat between the interior and exterior of a building. It aims to stabilize indoor temperature, reduce the loss of heated or cooled air, and improve energy efficiency. Insulation achieves this by impeding three main modes of heat transfer: conduction, convection, and radiation.


Conduction is the transfer of heat through solid materials. When there is a temperature difference between the inside and outside of a building, heat naturally flows from the warmer side to the cooler side. Insulation materials have low thermal conductivity, meaning they are poor conductors of heat. When installed in walls, ceilings, or floors, these materials help to slow down the movement of heat through the building envelope.


Convection is the transfer of heat through the movement of fluids, such as air. In homes, this often occurs when warm air rises and escapes through gaps or cracks while cooler air enters the building to replace it. Proper insulation, combined with air sealing, reduces convective heat loss by minimizing the movement of air between the interior and exterior of the house.


Radiation is the transfer of heat in the form of electromagnetic waves. All objects emit and absorb radiant heat, which can contribute to heat gain or loss. Insulation materials, especially those with reflective surfaces, can reduce radiant heat transfer by returning the heat to its source.

Types of Home Insulation

Are you looking for ways to make your home more eco-friendly?

If so, you’re probably wondering how to insulate your home and make it more energy efficient.

The good news is that plenty of options are available when it comes to insulation, and each type has its own benefits and drawbacks. Here are some of the best types of insulation:

Fiberglass Insulation

Fiberglass insulation is the most common type of home insulation and for good reason. Fiberglass insulation is one of the most widely used insulation types, accounting for approximately 85% of all insulation materials used in residential buildings in the United States. It’s relatively easy to install and very effective in helping you keep your home warm in winter and cool in summer. Fiberglass insulation is made with glass fibers woven together into a blanket that can be installed between walls or floors and ceilings.

Cellulose Insulation

Cellulose is another type of home insulation that has been around since the late 1800s. It’s made from recycled newspaper that’s shredded into fibers, then packaged into batts or sheets that can be installed between walls or floors, and ceilings. Cellulose insulation is gaining popularity due to its eco-friendly nature. It is made from up to 85% recycled content and takes less energy to manufacture than other insulation materials. Cellulose insulates well, but it doesn’t provide any fire protection, so it needs to be combined with other types of insulation if you’re concerned about fire safety.

Spray Foam Insulation

Spray foam insulation Phoenix is a foam-like material that can be sprayed into cracks, crevices, and other small spaces to seal them. It’s usually made from polyurethane or isocyanate, which are both synthetic chemicals. The spray foam is applied as a liquid and expands when it’s sprayed. This type of insulation also has good sound-dampening qualities because it fills in holes and cracks that allow noise to travel through the building structure. Spray foam insulation can be used on all kinds of surfaces, including wood, brick, stucco, concrete block, stone, and even metal. If you are looking for spray foam insulation near me, then call Ideal Air Conditioning and Insulation experts!

Mineral Wool/Rockwool Insulation

Mineral wool/rock wool insulation consists of a combination of minerals (usually silicates) that are formed into fibers by heat or pressure. These fibers are mixed with a binder material like resin and pressed into sheets for installation in walls or ceilings as an air barrier. The fiberglass sheets have a high R-value per inch (R-19 per inch for 1x2x8), but they don’t perform well as vapor barriers because they’re permeable to water vapor molecules. 

Polyurethane Foam Board Insulation

Polyurethane foam board insulation is an excellent option for areas that need a high R-value. It’s easy to install and can be installed on walls, ceilings, and floors. Polyurethane foam board can be used as a replacement for traditional insulations like fiberglass or cellulose.

Reflective Insulation

Reflective insulation is made from aluminum foil or foil-faced polyisocyanurate (R-38). These products reflect heat from your home back inside rather than allowing it to escape outside through cracks or holes in your walls or roof. Reflecting heat with reflective insulation will help reduce energy bills by up to 15%!

Polystyrene Insulation

Polystyrene insulation is a type of foam insulation that can be blown into a wall or cut and fit around windows and doors. It’s very lightweight, so it doesn’t take up much space in your walls, but it works great at keeping heat out of your home. Expanded Polystyrene (EPS) accounts for approximately 46% of the total thermal insulation market, while Extruded Polystyrene (XPS) accounts for around 27%.

Cotton Insulation

Cotton insulation is made from recycled cotton fibers that are compressed into batting or rolls for use as insulation. It’s a good choice if you want to reduce your carbon footprint or are environmentally conscious—it’s also easy to install and works well at keeping heat in your home during winter (but not so much during summer).

Aerogel Insulation

Aerogels are solid materials that are made up of a network of tiny hollow tubes. These tubes hold air and can be used to insulate your home. Aerogels are highly effective at trapping air, which means they’re extremely good at retaining heat. Aerogels are also incredibly absorbent, so they’re great at keeping water away from the walls of your house. This makes them well-suited for use in areas prone to flooding or high humidity.

Where Can You Insulate?

Insulation is a great way to save money on your energy bills and make your home more comfortable. 

But where exactly should you put it? You can insulate various areas of your home to improve energy efficiency and maintain a comfortable indoor environment. Here are the common areas where you can insulate:


Your attic insulation Phoenix, AZ, is an important part of your home and can be insulated. The attic insulation Phoenix is the space between the roof and the ceiling, where you store items that don’t fit elsewhere in your home. Attic insulation can help reduce your energy bills and make your home’s temperature more consistent throughout the year.

Insulate Walls

When you insulate walls in your home, it can save you dollars on heating and cooling costs. If you live in a cold climate and have a poorly insulated wall, it could cause damage to your property as well as increase heating costs because it will take longer for heat from inside the house to warm up everything outside of it when temperatures drop below freezing outside during winter months.

Basement and Crawlspace

Basements are notorious for being cold during the winter months. If you’re looking for an affordable way to insulate your basement or crawlspace, look no further than spray foam insulation! Not only will proper insulation help keep moisture out of your basement or crawlspace, but it will also decrease the chance of mold growth in those areas. This type of insulation also works well on crawl spaces because it’s lightweight and easy to install.


Floors are another area that often gets overlooked when it comes to insulation. Floors can be made of concrete or tile, so they tend to get cold during the winter months and hot during the summer months. Insulating your floor will help reduce these temperature fluctuations by keeping heat in during winter and cooling out in summer.

Windows and Doors

Windows and garage door insulation will help keep the cold and heat out. This is especially important if you live in a cold climate, where temperatures can drop to -20 degrees Celsius or lower. You can search for professional spray foam insulation near me or buy foam insulation kits that attach to the outside of your house and fill in the space between the door frames and exterior walls. The foam can be painted over to match the color of your house so it doesn’t stand out.

Roof and Ceiling

Insulating these two areas will help reduce heat loss from your home, especially if gaps or cracks in these spaces let cold air inside during winter when temperatures go below zero degrees Celsius or lower (depending on where you live). Adding insulation over existing insulation may also help reduce noise from outside sources such as traffic jams or airplanes flying overhead due to increased soundproofing properties that come along with having more insulation around these areas inside your home!

Don’t Let Your Ductwork Go Cold!

Ductwork is a major area of heat loss in many homes. If you haven’t insulated your ducts, it’s time to get to it. The best way to insulate ductwork is by using fiberglass insulation. This can be added directly to the metal ducts themselves or blown into the space between the metal and the insulation that’s already there. Either way will work, but fiberglass is better for sealing out air gaps and cracks than other types of insulation.

Don’t Forget About Those Air Gaps And Cracks! 

The places where ductwork meets other things like walls and floors (or even up against each other) are often areas that let cold air into your home. You can fill these gaps with foam sealant, but it’s easier if you use foam tape instead—it adheres better than sealant does and won’t peel off over time.
