Air Sealing and Insulation

Properly air sealing and insulating your home will not only help reduce your heating and cooling costs, but also make your home more comfortable.

Infrared Scan One of the most important jobs of a building enclosure is stopping air. Next to rain, air leaks through walls, roofs, and floors can have the most damaging effect on the durability of a home. Uncontrolled airflow through the shell not only carries moisture into framing cavities, causing mold and rot, but it can also account for a huge portion of a home's energy use and can cause indoor-air-quality issues.


Sealing A tight house is better than a leaky house, with a caveat - a tight house without a ventilation system is just as bad as a leaky house with no ventilation system. Energy efficiency requires a tight shell and good indoor-air quality requires fresh outdoor air. Ideally, the fresh air should come from a known source at a known rate not from random accidental leaks of unknown size and quantity. For this to happen, the house needs an adequate air barrier and a controlled ventilation path.

Where do the leaks come from?
The US Department of Energy lists how much air leakage can occur in an average American home from various locations: Ceiling, walls and floors - 31%; ducts - 15%; fireplace - 14%; plumbing penetrations - 13%; doors - 11%; windows - 10%; fans and vents - 4%; and electrical outlets - 2%.

How much can you typically save?
Sealing and insulating the "envelope" or "shell" of your home-its outer walls, ceiling, windows, doors, and floors-is often the most cost effective way to improve energy efficiency and comfort.

The amount of energy and money you will save depends on the amount of air leakage you have. If your home is newer and well-built, your savings could be around 5-20%. For older homes, the savings can be more than a 50% reduction of heating and cooling costs. The average energy savings we are able to achieve is around 30%. No matter the age of your home it's important to get an energy audit to determine the extent of your air leakage. (Source: www.energystar.gov)

Efficiency Matters uses the latest technology and greenest materials to seal your home. We offer all kinds of insulation services from blown in loose fill to rigid foam. Call us today for a free consultation.

Examples:

Attic insulation - We use cellulose insulation for 98% of all of our jobs. We strongly believe that cellulose insulation is better for you than fiberglass (and others) in many ways including indoor air quality, R-value per inch, sound proofing and overall air barrier properties. The cellulose insulation we use is manufactured locally out of Penrose, Colorado and is made up of 85% recycled materials. The R-value is 3.6 per inch when applied as loose fill in your attic.

Vacuum and air seal attic - We use a 15hp vacuum to temporarily or permanently remove the insulation in your attic so that we can approach the attic as if it were brand new. Taking out the insulation allows us to see all of the penetrations throughout your attic. We consider this approach best practice and you'll gain the most in energy savings and comfort from this method. We use 2-part Handi Foam to seal all penetrations and top plates including the top plates at the exterior wall.

Dense pack exterior walls - We can dense packing your exterior walls with cellulose insulation by using a method called drill and fill. We will place wood plugs when done.

Insulating & Spray foam attic walls - Installing a spray foam to your attic walls will increase the R-value and add an air barrier. Air infiltrating your home can be one of the main causes of uncomfortable drafts and high energy bills for many homeowners.

Seal around furnace flue - Here we installed a metal collar around a furnace flue which will keep insulation 2" away from the fire source. We also sealed around the flue connection with fire rated caulk and/or spray foam.

What our customers are saying

At Efficiency Matters, your comfort and complete satisfaction is our top priority.
We would be glad to provide references so you can hear about us first hand.

Here are just a few examples of what our customers are saying.


Jim and Karin Higgins of Fort Collins, CO
In the fall Efficiency Matters did a major upgrade to the efficiency of our home. It turned out we had a home with many air leaks that were robbing us of needed heat in the winter and we were losing our cool in the summer. Efficiency Matters did a comprehensive analysis of the house and recommended several things that could be done to tighten the house and make our heating and cooling systems operate more efficiently. Recommendations were made considering the return on investment value. We have gone through a winter and half of a very hot summer and could not be more pleased. Our utility bills are roughly half what they used to be. Great job Efficiency Matters, I will recommend your services to anyone.

Ryan and Katy Kirkpatrick of Wellington, CO
"We would definitely recommend having an energy audit done by Efficiency Matters.
Greg was knowledgeable, professional and honest. We really appreciated that he told us about many improvements that we could do ourselves (and exactly how to do them), in addition to completing two larger improvements for us. We found the price of these “retrofits” reasonable and workmanship excellent! As first-time homeowners, this was a great investment for us and we are very happy with the company we chose. Thanks Greg!"

Gary Zook of Fort Collins, CO
I would describe Greg as honest, thoughtful, conscientious, thorough, and hard working. I've worked with many contractors through the years and while most of them do a decent job, a few of them really impress with both their skills and attitude. Greg is one of the best and I would not hesitate to recommend him for improving the energy efficiency of your home.

Scott Rogers of Windsor, CO
Greg, I wanted to give you a follow-up on how things are working. Since yesterday was such a hot day we really got to see how things were working. I must say we are VERY HAPPY with the results. Amy said the house stayed very cool until after 7:00PM. Then the A/C came on for only a few minutes. We used the Whole House Fan around 9:00 PM and it cooled the upstairs 2 degrees (making the whole house the same temp). We slept very comfortably last night. This is exactly the results we were hoping for. Thank you so much!
