Attic Insulation & Air Sealing in Denver, CO

At NetZero Insulation, we have spent nearly three decades helping property owners all over Denver, CO with their construction projects, from attic insulation services to home energy audits. The fact is, most homes in the United States don’t have enough insulation, which results in significant and often costly air leaks. Even more so, if you added up all the leaks, holes, and gaps in a typical home’s envelope, it would be the equivalent of having a window open every day of the year! This can easily be avoided by calling on our seasoned team for professional air sealing and attic insulation services.

Comprehensive Insulation Services for Your Property

When you have a house with gaps and holes – even tiny ones – you could be costing yourself a great deal of money and causing major health problems for yourself and your family. Air sealing your attic is a great way to prevent these, among other issues associated with insufficient insulation. The air sealing process begins with testing the attic to find where the leaks are likely coming from in your space. Once the culprit areas are identified, our team will use a type of expanding spray foam insulation to seal up any gaps or cracks and prevent airflow. This process helps to make your insulation more effective and will do wonders in improving your home’s overall energy efficiency and comfort. The following are additional areas our team will evaluate for air leaks:

• Plumbing and wiring penetrations through the attic floor
• HVAC ductwork, chases, vents, and registers
• Chimney chases
• Attic access hatches, doors, and drop-down stairs
• Recessed lights and fans in ceilings

Why Is Air Sealing Important?

At NetZero Insulation, we feel it’s our duty as Denver’s premier choice for insulation services to educate our clients on the importance of properly air sealing their homes. Here are some things we want you to know regarding the importance of air sealing your space:

Efficiently prevent air leaks

Air leakage in homes is responsible for 15% to 40% of heat loss and gain. This means your monthly electric bill could be significantly higher than it needs to be, as your heating and air conditioning system works harder to heat or cool your house. Air sealing your space eliminates this air from escaping, saving you more money in the long run.

Choose superior resistance

The movement of air through insulation reduces its R-value by as much as 80%. R-value is a measure of thermal resistance that determines how well an object resists conductive heat flow. The measurement is determined based on testing methods created by the American Society of Testing and Materials (ATSM), which factor thickness, material, and installed weight per square foot into the assessment. The less resistant an object is the more heat escapes. Air sealing solutions help to minimize air movement, causing less to escape through your insulation.

Avoid health issues

A leaky home can result in potential health hazards for those inhabiting it. With gaps in your air ducts, vent fans, attic door insulation, and different objects, it’s easy for external contaminants to enter your home. These can include allergens such as pollen and dust, as well as insects and other pests. Additional irritants are mold and mildew, which can form when humidity is able to infiltrate your home and migrate to the attic.

Diminish potentially dangerous pathways

Should your property have the misfortune of suffering through a fire, a poorly sealed home could significantly add to the damage. Quality air sealing works to reduce the pathways in which fire and smoke can move through your home. With proper insulation services and air sealing, you are also less likely to have to deal with ice dams forming on your roof.

Gain peace, quiet, and comfort

As for the comfort of your home, professional insulation services and air sealing can positively impact that as well. An efficiently-sealed home does well to keep the outside noises from interrupting your sleep, TV watching, and reading. Even if you live on a busy street where kids yell, neighbors blow leaves and mow their lawns, or cars and motorcycles are continually speeding by, you will enjoy ultimate peace and quiet. Also, your comfort will be improved, as drafts are lessened when capable professionals have sealed your home.

There are air sealing measures required by code on all new construction projects. It is also an obligation to qualify for the Xcel Energy Rebate Programs. As long-time professionals in this industry, we can set you up with air sealing solutions specifically designed to improve attic insulation.

Why Remove Insulation First?

In some instances, it may be more economical or necessary for complete accessibility to remove existing attic insulation prior to air sealing. This provides us 100% visibility to all penetrations, such as vent pipes, flues, chimneys, electrical access holes, chases, and wall top plates. Oftentimes, the removed insulation can be reused for your project, saving you on material costs. At NetZero Insulation, we pride ourselves on being honest and always providing the best service in the industry. We are not salespeople, and we’ll never use any high-pressure sales processes to get more money out of our customers. Our hand-picked team will spend as much time as you want to show and educate you on potential upgrades to your home. We want you to be able to get the insulation services you need, no matter your budget. For more information on how you could save through our insulation services, check out our Rebates Page.
