Candace from The Green Cocoon Performs a Blower Door Test

Why You Need Blower Door Testing

Home Maintenance Tips
Blower door testing helps us understand where structures leak and is the first step toward building tighter, more energy-efficient homes.

What is a blower door test?

The purpose of Blower Door Testing is to measure the air tightness of a home and check for air leakage. A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings.

These are some reasons for establishing the proper building tightness:
  • Reducing energy consumption from excess air leakage
  • Avoiding moisture condensation problems
  • Avoiding uncomfortable drafts caused by cold or warm air leaking in from outside
  • Controlling outdoor contaminants, pests, and odors from entering your home.
  • Determining proper sizing and airflow requirements of heating and cooling equipment.
  • Determining whether mechanical ventilation is needed to provide acceptable fresh air and maintain indoor air quality in your home.

Determine the air infiltration rate

green-cocoon-thermal-imaging-1While the blower test is being conducted, our insulation specialist may use an infrared camera to look at the walls, ceilings, and floors. Moreover, this test finds specific locations where insulation is missing and air is leaking.

Preparing for a blower door test

Our experienced insulation specialist performs the blower door test. This includes a walk-through of your home, setting up the blower door, and conducting the test. The following steps will help prepare your home for a blower door test:
  • Plan to do a walk-through of your home with the specialist. Be prepared to point out areas that you know are drafty or difficult to condition comfortably.
  • Expect the specialist to request access to all areas of your home including closets, built-in cabinets, attics, crawl spaces, and any unused rooms.
  • The specialist will need to close all exterior doors and windows, open all interior doors, and close any fireplace dampers, doors, and woodstove air inlets.
  • If you heat with wood, be sure all fires are completely out – not even coals – before the specialist arrives. Remove any ashes from open fireplaces.
  • Expect the specialist to set controls on all atmospheric fossil fuel appliances (e.g., furnace, water heater, fireplaces, and stoves) to ensure that they do not fire during the test. The specialist should return them to the original position after the test.
  • Expect the test to take up to an hour or more, depending on the complexity of your home.

The Green Cocoon offers custom, cost-effective solutions to make your home or office building more comfortable. Additionally, this saves you money on your energy bills. Our troubleshooting and diagnostic skills separate us from the pack! For more information, contact us

Why Use an Insulation Expert

Insulation Tips

Why use an insulation expert? Because when insulation isn’t installed correctly things happen!

Apartment complex - The Green Cocoon InsulationThe Green Cocoon received a call from the manager of an apartment complex because they had frozen pipes in the attic. What we discovered was that the insulation was placed incorrectly, and they didn’t add enough of it over the pipes. Consequently, the pipes were freezing.

cellulose-the-green-cocoon-insulation

Difficult Location

The pipes were in the far back corner of the very large attic. So our VP Candace was the lucky one who got to walk on a small 2 x 4 catwalk to find the problem. And she did! Just take a look at how dirty she got after crawling around in the cellulose!

Cover Your Tracks

It is very important to cover your tracks after walking in cellulose insulation. Candace made sure she did just that! If not covered, all of the holes created by her footprints would leave cold spots.

Use an expert

Whether you are building an apartment complex or updating the insulation in your attic, make sure to use an insulation expert. Your wallet will thank you!

Importance of Vapor Barriers and Ventilation

Insulation Tips

Recently, our vice president Candace was asked to take a look at a property and give a quote for insulation. Our sales staff usually videotapes their meetings with clients to help them decide on the best insulation for the job. We wanted to share this video to show you the importance of vapor barriers and ventilation.

vapor-barriers-and-ventilation-the-green-cocoon

Thermal Bridging and Condensation

In the first part of this video, you will see water droplets dripping off the nails that are poking through. Because the nails were put in from the outside on the north facing part of the house where there is not a lot of sunlight, there is thermal bridging. Consequently, any moisture that comes in is hitting the wood and making it wet. But the nails are where the water is condensing. As the water runs down the wall and gets closer to the floor, you can see that there is frost in the soffit. Because heat rises, the soffit is much colder.

Add a Vapor Barrier

Adding ventilation can temporarily solve this problem, but then heat and moisture would be pulled from the house even faster. And, losing heat is not energy-efficient. What should happen is a vapor barrier should be created at the thermal envelope to prevent the moisture from ever getting into the space. The other alternative is to spray foam the roof so the surface of the roof is protected by the foam. And because of its R-value, the surface of the foam will never be cold enough for the moisture to reach a dew point and condense.

At 38 seconds, you will see that on the other side of the house, there is an identical eve space that is significantly warmer. In fact, it is 20 to 30 degrees warmer, and there is no moisture. Consequently, the nail heads don’t show any rust. This is a good example of why vapor barriers and ventilation are important.

Insulation Is Key

Our recent blog about Rockwool insulation being designed for use as exterior continuous insulation is a great read. It will help you understand the importance of vapor barriers and ventilation.
