Air Sealing & Energy Audits in Jasper, IN

Air sealing involves locating and closing gaps, cracks, and penetrations in the building envelope that allow unconditioned outside air to enter and conditioned indoor air to escape. These air leaks are often found around windows, doors, plumbing penetrations, attic access points, recessed lighting, and basement rim joists.

Common Air Leakage Points in Jasper Homes

Older homes in Jasper frequently contain unsealed joints or poorly insulated features that contribute to energy loss. In many cases, insulation alone isn’t enough—if air is able to bypass insulation, thermal performance is compromised. Polytec Solutions identifies and seals these leaks to create a more consistent and controlled indoor environment.

Types of Sealing Materials Used

Depending on the size and nature of the gaps, a combination of caulks, expanding spray foam, weatherstripping, and sealants is used. These materials are selected for their compatibility with different surfaces and durability through Jasper’s climate conditions, which include humidity, freezing temperatures, and heat.

Before air sealing can be effectively implemented, an energy audit is performed to evaluate how the building is using—and losing—energy. Polytec Solutions conducts thorough diagnostic assessments to determine where performance can be improved, offering a roadmap for energy upgrades.

Blower Door Testing

A blower door test is used to pressurize or depressurize the building and measure how much air leaks through the structure. This test reveals the air infiltration rate and helps pinpoint leakage locations. In Jasper homes, blower door testing often uncovers leaks in areas previously overlooked, such as dropped ceilings, soffits, or behind knee walls.

Infrared Thermographic Scanning

Using infrared cameras, our team visualizes temperature differences across walls, ceilings, and floors. These images highlight areas where insulation is missing or ineffective, guiding both air sealing and insulation improvements. This method is especially valuable in Jasper’s mixed-season climate, where performance needs vary throughout the year.

Duct Leakage Testing

For buildings with forced-air HVAC systems, leaky ducts can be a major source of energy loss. Duct leakage testing evaluates the integrity of your ductwork and identifies whether sealing or insulation is needed in attics, basements, or crawl spaces.

After the energy audit, Polytec Solutions provides a report detailing the areas of improvement along with recommendations for sealing, insulation upgrades, and moisture control solutions. Each recommendation is based on performance metrics and regional building standards specific to Jasper, IN.

Prioritizing Air Sealing Before Insulation

In many cases, air sealing should be completed before new insulation is added. Sealing prevents air from moving through or around insulation, which enhances the R-value and thermal resistance of the overall system. This staged approach is common in older Jasper homes where insulation is being updated after decades of settling or degradation.

Reducing HVAC Loads

By sealing air leaks, conditioned air remains inside the building longer, reducing the frequency and duration that heating or cooling equipment must operate. This not only lowers energy bills but also extends the life of HVAC systems, a crucial benefit during Jasper’s temperature extremes.

In addition to energy savings, air sealing and auditing improve indoor comfort and air quality. Drafty rooms, uneven temperatures, and dry winter air are common complaints in leaky homes across Jasper. Sealing helps stabilize temperature zones and reduce dust and allergen infiltration.

Moisture and Mold Control

Air movement through walls or floors often brings moisture into building cavities. When humid outdoor air meets cooler indoor surfaces, condensation occurs, leading to mold and material degradation. Proper air sealing reduces these conditions and complements mold prevention strategies.

Polytec Solutions ensures that all air sealing and energy efficiency improvements align with Indiana’s energy codes and local Jasper building standards. Our energy audits can also help homeowners qualify for rebates or incentives through utility-sponsored energy efficiency programs.

Documentation for Incentives

For property owners pursuing tax credits or energy upgrade rebates, we provide documentation and test results that verify the effectiveness of each improvement. This includes blower door test data, thermal images, and before-and-after assessments.
