Stop Air Leakage To Boost Energy Efficiency

Many homes in southern Pennsylvania face air leakage and drafts. By adding an airtight seal to key areas in your thermal envelope, you can lower your energy costs.

Air Leakage Problems

Why Should I Invest In An Air-Seal?

High Energy Bills

When air leaks, so does heat. This leads to a hot house in the summer and a freezing home in the winter. Adding an air-seal supports your HVAC system.

Poor Air Quality

If air can leak, air pollution can leak with it. In southern PA, that means the smells of manure, factory pollution, and burnt trash can sneak into your home.

Pest Infestations

Insects and rodents often use areas of air leakage as pathways into your home. An airtight seal cuts off these entry points.

Home Discomfort

Air leakage contributes to fluctuating temperatures in your home. With an air-seal, you can more easily condition your air because it stays inside.

Your Thermal Envelope

Where To Add An Airtight Seal

You can add an air-seal anywhere in your thermal envelope. The thermal envelope is the outer shell of your home, separating the conditioned space inside from the external environment.

Your Attic Or Roof

Air leakage in the attic causes problems in the summer and winter. In summer, hot air presses from your attic into your living space. In the winter, the heat you pay for escapes through the attic. An air-seal helps your home stay more comfortable all year long.

Your Exterior Walls

In a new construction home, you have the opportunity to add an airtight seal to your walls. Otherwise, air will exchange uncontrollably through your walls. It has a similar effect to leaving a door or window open.

Your Basement Rim Joists

The band boards of a basement are a common culprit for air leakage. Masonry meets wood. Without an airtight seal, cold air will be sucked into your home through the rim joists, especially during the winter.

Your Crawl Space

If your home has a crawl space, it faces similar air leakage as a basement. The biggest difference is that most crawl spaces are musty and moldy. You breathe crawl space air anytime there is air exchange.

Benefits Of Air-Sealing

Some benefits of air-sealing vary by application.

Building Science Behind Air-Sealing

Heat Travels Through The Air

The goal of insulation is to stop heat transfer. R-value, or resistance value, is the measurement of how well a material can resist conductive heat transfer. All insulation materials need a high R-value.

But R-value doesn't tell us anything about how well a material resists convective and radiant heat transfer.

While heat does travel directly, like from a stovetop to a pan, it also travels through the air. Convection heat is how heat circulates through the air, and radiation is why you can feel the warmth of the sun when you stand outside in the winter.

All insulations can combat conduction heat, but not all insulations can slow convection or radiation. Adding an air-seal makes your insulation more effective.
