The Benefits of Quality Insulation

A Comfortable Living Environment

Keep the outside air out and the inside air in throughout the year and especially during Maryland’s extreme seasons! Are you tired of waking up and your home is either freezing cold or boiling hot? If your home is poorly insulated, it can cost you the comfort you rightfully deserve. Did you know that if your home is poorly insulated you can lose up to 3 degrees of heat per hour? That means your home’s interior can go from 70 degrees to 46 degrees in the eight hours that you’re asleep! You deserve to feel comfortable in your home no matter what the outdoor temperature is.

Lower Utility Bills

One of the biggest benefits of having your home or property properly insulated is lower utility bills. You have two options: maintain the temperature in your home with quality insulation or replace it with a thermostat which can drain your wallet sooner than you think. Installing insulation in your walls, crawl spaces, and attic can lower heat loss by .5 degree per hour! Just imagine no longer having to turn on the thermostat and going to bed and waking up to perfect temperatures in your home.

Extend Your HVAC System’s Life

Last but certainly not least, insulation can greatly extend the life of your HVAC system because you will use it less by better containing the heat in your home. Your HVAC equipment can last twice as long if your house is well insulated! So not only will you be saving money, but you will help protect the environment by using less fuel, propane, natural gas, and electricity, which pollute the air.

What is Spray Foam Insulation?

This specific material and technique has several benefits. It can save substantial amounts of money on utility bills, it prevents mold and mildew growth and their harmful effects, and enhances the effectiveness of HVAC systems in your residential or commercial property. Spray foam is the more expensive option compared to other popular types like cellulose and fiberglass; however, the prices are worth the end result. It is made of a polymer and completely fills in all spaces and gaps as it expands when sprayed. Therefore, it keeps your home’s indoor temperature comfortable year round. 

Which Insulation Should You Choose?

Other common materials like fiberglass and cellulose have several benefits, and each type is good for different jobs. Therefore, it’s important to consider all the pros and cons of each type as well as the size and scope of your individual project so you can make the right decision regarding which one to use.


Fiberglass is one of the most popular types used throughout the country. It’s a cost-effective option and provides a nice sound barrier. It also comes in both sheets and batts (rolls) and offers flexibility in the amount that can be installed in different spaces around your property. For example, if you have an area in your home where a lot of outdoor air is able to get in (such as near windows), you can install more fiberglass in that area for improved thermal protection. Fiberglass is also fire resistant and environmentally friendly as between 50-80% of it is recycled glass fibers which otherwise would have gone to the landfill. This insulation is also moisture resistant and can be used in a variety of spaces including attics, crawl spaces, open walls, and joists. Overall, if you’re looking for a cost-effective option that you can do yourself, fiberglass might be the choice for you.

Two downsides of this option that you must consider are that it is extremely dangerous to inhale and can cause skin irritations during the installation process, and if it’s not done correctly there will be gaps that allow outside air to seep in. We recommend hiring a professional to install this for you so you can avoid these potential risks. However, if you are willing to spend more on upfront costs for increased protection from the outdoor temperatures, you can also consider using spray foam.


Cellulose is composed of recycled paper or wood, making it another environmentally-friendly option and safer to handle. This material is commonly used in attics and enclosed walls because of how efficient it is to install. Loose-fill, blow-in cellulose is best in enclosed spaces because it easily fits around objects (ducts, wires, etc.) commonly found in these hard-to-reach spaces. This material is a cost-effective insulation that provides solid thermal coverage for your home.

A couple of drawbacks of cellulose to consider are that over time, as it settles, it can leave gaps where outside air can enter, and it is not moisture resistant. When it retains moisture, it becomes susceptible to mold and mildew growth. As a result, the R-value significantly decreases, leaving your property vulnerable to the outdoor temperatures.

Spray Foam

Unlike fiberglass and cellulose, spray foam is not made out of recycled products but rather is composed of polyurethane or latex. It is effective for both large and small jobs and expands when it is sprayed, providing a thorough seal from the outside air. Another benefit is that once applied, it settles rather quickly and you can paint, trim it down, and stain it! Spray foam comes in open-cell and closed-cell foam which have R-values of about 3.7 and 6.2 per inch of thickness, respectively. Open-cell remains soft and is a good sound barrier; closed-cell is more expensive and hardens, providing strong thermal protection. Another major benefit of this type is that it is extremely mold and mildew resistant, making it longer lasting than its alternatives made of recycled material. 

Some downside of spray foam that you should consider is that because it uses chemical compounds called “isocyanates,” it can cause eye irritation and respiratory issues if not mixed and applied correctly. It also requires industry experience to install as there are specific mixing and application standards to follow. So, if you’re looking to do a DIY project, spray foam is not the choice for you. However, considering the long-term effectiveness and durability of this material, hiring a professional installer may be worth it for you in the long run.
