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.
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.
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.

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.

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.

Air-Sealing FAQs
What Services Include Air-Sealing?
Air-sealing is included in all of our insulation services. When you have spray foam insulation installed, you automatically benefit from an airtight seal.
Our team also includes an air-seal with blown-in insulation in attics.
What Products Do You Use For Air-Sealing?
South Central Services uses closed cell spray foam, open cell spray foam, can foam, and silicone caulking to create an airtight seal. Which product we use depends on your project.
Does Air-Sealing Qualify For Tax Incentives?
Air-sealing does qualify for a federal tax credit called 25C. Air-sealing falls under the insulation section.
