So you’re insulating your attic. Or maybe you’re considering re-insulating your attic. Either way–we’ve got you covered. Below is everything you need to know about insulating your attic. Let’s get started!
We’re glad you asked. As we’re sure you know, your attic covers the entirety of your home. The air that's conducted into the rest of your house begins in your attic. Therefore, making sure that your attic is insulated properly is imperative to the health of the rest of the home. A poorly insulated attic is likely to take a toll on your heating and cooling system. This is because your HVAC will have to work harder to keep the rest of your house at the desired temperature. And with all that work from your HVAC unit comes much higher energy bills. Who wants that?!
Additionally, an attic that is poorly insulated will allow for excess moisture in the areas that aren’t insulated. Though this may not seem like a huge problem, moisture build up will eventually lead to some bigger issues. More than likely, these issues will be mold growth. Once mold begins to grow in your attic, it soon begins to hinder the air quality of your home. Though not easy to get rid of, fortunately mold remediation can take care of this problem.
Lastly, substandard insulation in your attic can lead to some significant pest problems. During cold times of the year, pests like rodents, cockroaches and spiders are looking for a warm place to go. Notoriously, pests like these find their way to attics. With proper insulation and air sealing, pests have no way to get in. However, issues like old and worn insulation make it easy for pests to chew their way into your home. Yuck!
Before we begin, let’s go over some basic attic insulation terms:Insulation is the material installed in walls, ceilings, floors and in this case–attics! Heat transfer: Or heat transmission, is the movement of heat through one material to another (which is what insulation is meant to prevent) Faced insulation: Has a vapor barrier that helps prevent moisture from moving from one space to another. It is also in preventing downward heat flow. (i.e. fiberglass batts) Unfaced insulation is used when new insulation is being added to existing insulation (i.e. spray foam and fiberglass) R-value is the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power. Closed-cell SPF is a form of spray foam insulation that provides added structural strength and hard vapor protection Open-cell SPF is a form of spray foam insulation that offers the same insulation benefits as closed-cell but doesn’t act as a water or vapor barrier
Now that we've gone over the basics, let's take a look at the most common forms insulation for attics.
The type of insulation you use in your attic will depend on how old your home is and what you’re looking to get out of the insulation. As we know, some common reasons why homeowners try to keep up on their attic insulation is to: reduce energy expenses, prevent moisture and mold, protect your home from pests, and more. Below are a few common attic insulation materials and their benefits.
Loose fill (or blown-in insulation) is a highly eco-friendly and energy efficient form of insulation. With its high percentage of recycled content, loose-fill insulation provides a dense, effective barrier against heat loss–which is something attics see a lot of.Best for…
Spray foam insulation, also known as spray polyurethane foam (SPF) insulation, is the most advanced, energy-efficient insulation on the market. You can choose between open-cell SPF which, as we know, offers structural strength with a vapor barrier. Or you can choose closed-cell SPF which offers structural strength without the vapor barrier.Best for…
Fiberglass insulation is fine glass fibers and contains anywhere from 25 to 50% recycled content. It’s R-value ranges anywhere from R-8 to R-38, making it highly heat resistant. This insulation is the most cost effective and arguably the quickest to install yourself.Best for…
As you might recall, using a loose-fill or blown-in insulation is great for adding to pre-existing insulation. It also tends to be a lot easier to install yourself. When going at it alone, though, it’s important that you set yourself up for success. Below is a checklist of items to complete before beginning your insulation process.
As fun as it sounds, insulating your attic yourself is quite a large task.
