VIDEO 1:14 – Reveals the Most Expensive Insulation Mistake & How To Avoid It!

According to the US Dept of Energy, the average house air leakage equals to a 2ft x 2ft window being open 24/7. If you are trying to cool your house, don’t you think it would be smart to close the window and stop all the air from leaking out?

What if I wait & air seal later?

It is a huge mistake to add more insulation now without air sealing. Insulating without first air sealing is like putting a bandaid on the problem. It doesn’t fix it.

Plus, when you decide to fix the problem by air sealing it will be more expensive. Why? If you add more insulation now…

  • you pay more to have all the insulation in your attic removed
  • the money you spent to have the ineffective insulation installed is sucked out and thrown away.

Where Stellrr Air Seals

Stellrr helps you stop losing air you paid to condition by sealing:

  • drywall on entire perimeter of the house on both sides of the top plates
  • drywall on all interior wall top plates on both sides
  • light switch electrical penetrations in top plates 
  • electric outlet wire penetration in top plates 
  • each bathroom hot & cold water pipe penetrations
  • kitchen and laundry hot & cold water pipe penetrations
  • each sink, toilet, tub, shower 2” drain pipe
  • each room’s electric box for fan/light (not recessed lights)
  • all audio, cable, etc electric penetrations in top plates

Air sealing allows us to manage the moisture, and kill off dust mites, fungal, mold, and viruses that grow in high humidity.

Insulating without air sealing is mal-practice.


Can you see how insulation without air sealing results in a uncomfortable & inefficient home?
