When Good Air Leaks Out, Bad Air Leaks In!

Understanding the "Stack Effect" - The laws of convection cause warm air in your house to move upward. The air goes through the attic and outside. As this air is lost, new air is drawn in from the crawlspace, basement, and outside air, to be heated again and lost again. This cycle of air loss from the top and infiltrating from the bottom is known as collectively as the "stack effect."

Small Air Leaks = Big Bills! - When houses lose air, you're left paying extra to heat, cool, and dehumidify air from the outside on a consistent basis. Air leaks are a huge waste of energy, making it even more costly to keep your house comfortable.

Dr. Energy Saver Des Moines says…

Dust and dirt Stains on fiberglass insulation are a visible sign of air leakage. It shows the insulation's filtering the air leaks and it traps dirt and dust the same way a furnace filter would. If you see dirt-stained insulation, your house is leaking air!

Joints = Air Leaks - Why do houses leak air? To start, your house is made of thousands of parts, including nails, boards, window casings, electrical wire, wall panels, pipes, etc. Gaps can form wherever one part of the house connects to another.

While a joint may be airtight on installation, that may not always be the case. Wood shrinks, materials expand and contract at different rates, and connections can come loose. Leakage points can form everywhere. Dr. Energy Saver Des Moines is the air sealing company that can help you fix any of these air leakage issues you may be facing in your home. Their qualified team is ready to tackle any challenge you are facing.

Contractors Make Air Leaks (and they can't help it!)

Air leaks are built into the construction of your house when it's being built.

When framing crews finish their work of making the house shell, other workers cut that shell apart for functionality.

Electricians, HVAC contractors, and plumbers drill and saw through the shell creating channels for wires, heating ducts, water lines, waste pipes etc.

The holes that are created don't compromise the home's strength, but they result in a network of leakage points that can let air out, and in. Air sealing these holes is a great idea because it will hopefully keep your home at a more comfortable temperature during the hot summer months or cold winter months.

Gaps in your house can be small, like the ones found around an electrical outlet in an exterior wall. But, large openings are common, like the ones created by plumbers in floors and framing as they install pipes, or the long gaps like the one created when the eave soffit does not meet the exterior wall in an airtight connection.

Seal Air Leaks & Save Money!

Sealing air leaks in a building is called "Air Sealing." But, finding air leaks is much easier said than done. Locating these leaks requires special equipment, training, and access to all parts of the house.

Once the leaks have been located, it's important to choose the best products and practices to properly air seal these areas.

No more leaks! - For many air sealing tasks, Dr. Energy Saver Des Moines recommends two-part foam. This leaves the nozzle in liquid form, and expands quickly to fill cracks and gaps. As it sets, the foam creates a barrier that's airtight insulation.
