Fast Facts About Air Sealing An Attic

Most homeowners with a basic working knowledge about insulation believe that the more insulation added to their home, the more energy efficient the house is.  While this is in part true, embracing the utilization of attic air sealing in tandem with insulation will produce the best results.  Here’s what you need to know!

What Is Air Sealing An Attic?

A critical step to improving your home’s energy efficiency, attic sealing is the meticulous process of locating and addressing areas of your attic that have allowed exterior air to filter in.  Spots that often require attention include can lights, false soffits, and bath fan penetrations.

Learn more about areas that benefit from attic air sealing to improve energy efficiency.

Spray foam, patches, and weather-stripping are used to fill in holes and cracks to create a tighter home.  Simply adding insulation does not fully address the root of the issue which is outside air making its way into the home.

Identifying Problematic Areas Related To Home Air Sealing

A reputable contractor, through the utilization of diagnostic testing, can work with you to determine areas where a home is leaking air.  Winter is an optimum time for a home energy evaluation because the interior of the home varies so much from the exterior home air temperature.  A heat map analysis utilizes thermal imaging which can rapidly allow a contractor to identify pockets of cold air within your home.

Home Performance Testing Is A Step to a More Energy Efficient Home:

Tread Lightly When Performing A DIY Air Sealing Project

While the process itself seems straightforward, there are numerous reasons the services of an attic insulation professional should be rendered.  Air sealing an attic changes the nature of your home’s building envelope which can be thought of as the components of the protective shell that separates the outdoors from the indoors.

When Sealing Attic Air Leaks Goes Wrong

In the event an amateur attempts attic air sealing and the home is made to be too tight, indoor air pollutants are left without an escape route.  At a minimum, this can lead to health concerns such as nausea and frequent headaches.  In extreme cases, notable damage from prolonged exposure can impact the liver, central nervous system, and kidneys.

A professional understands the steps that must be taken to address wet insulation and determine if the underlying cause is roofing, ventilation, or insulation related.  Precautionary measures must be taken to protect yourself when entering an attic with vermiculite insulation, which contains asbestos.  Care must also be taken to not disturb electrical work in an attic in order to prevent a house fire.

Attic Sealing Benefits

From a comfort, energy efficiency, and utility savings standpoint, home air sealing is a win.  Once all necessary areas have been properly sealed, your home’s interior temperature is better regulated, allowing your home heating systems, like a furnace, to run less.  Upon proper completion, there should be less of a variance between the temperatures in rooms throughout your home.  Attic air sealing and insulation services are the best way to ward off the risk of ice dams on your roof.  In addition, homeowners that have had attic sealing done will notice a quieter home, lower home air moisture and humidity, and a drop in the amount of dust circulating in the air.

"We used Lindus for a rather complicated attic re-insulation project. They are highly competent and do great work!"

"Jason and the insulating crew did a great job. I told Jason it looked like nothing was done when he finished cleaning, which is a very good thing.  The insulating crew did have a difficult time working under the bay window. They usually hold their spray gun about 2 ft. away from the surface. In our location, they only had a foot at the most. So, there was a lot of blowback, clean-up, and additional layers to get the final result."

"We hired Lindus for attic insulation and new LeafGuard® Gutters. We had an issue arise a couple years after the work was completed. I called Lindus and had no problem scheduling someone to review and create a plan. Randal has worked diligently to get to the bottom of the problem and fix it permanently. The company truly does stand by their product, a claim that is not always realized, but with Lindus has proven to be true. I am so appreciative and would recommend them to anyone."
