The Hayes Company helping Habitat for Humanity
Throughout our history, The Hayes Company has supported a variety of community projects. We believe in partnering with organizations that share this philosophy.

In 2016, Kansas City NARI is once again sponsoring a house with Habitat for Humanity of Kansas City. The Hayes Company is proud to be a volunteer contractor on their current project.

Our goal is to make this one of the most energy-efficient homes in Kansas City. To accomplish this goal, we’ve put great attention to detail into both insulating and air sealing the home. This has included air sealing around all windows, doors and where all framing joints meet. Sound control insulation was has been installed in all the bathrooms, drain lines and in the floor of the home’s third floor. Foam insulation was installed on all exterior walls and rim joists, and cellulose insulation was installed in the attic. Work of this caliber would normally cost $15,000 or more – all of which is being donated.

The project is going great! The insulation and air sealing work has been very effective. As a result, the HVAC contractor has decreased the size of the unit being installed in the home.

Mike O'Connell has been the lead insulator on this project, working with volunteers provided by Habitat for Humanity of Kansas City.
Our work has been done in partnership with A+ Insulation and Henges Insulation.

crawl space insulation
Winter is around the corner. Unless you’ve invested this year in home energy improvements, your home will be as inefficient and uncomfortable this winter as it was last winter.

If your home has a crawl space, sealing and insulating your crawl space can dramatically improve your home’s comfort, reduce energy bills and improve the quality of air inside your home.

Today’s building science proves that what’s beneath our home affects the comfort inside our home. A home’s natural airflow is from bottom to top (from the ground to sky). As your home naturally breathes, air is drawn up from the basement or crawl space, through the living area and out the attic. This natural airflow means air from a moist crawl space (and everything in the crawl space) flows up and into your home’s living area.

Here are three reasons to insulate your crawl space before winter:
  1. Improved Air Quality
    Crawl spaces are naturally damp. As your home breathes, air from your crawl space flows into your home’s living space through penetration points around wiring, plumbing holes and more. This means the air in your crawl space is mingling with the air you breathe every day. Not only is this distasteful, it’s unhealthy. Air sealing and insulating your crawl space will improve the air quality will help keep pollutants out of your home.
  2. Lower energy bills
    Does your furnace run more than you’d like during winter? This is a result of your HVAC system heating air from the crawl space that’s mingling with the air that’s already been heated. This means your HVAC system is continually working to maintain your home’s internal temperature. This results in higher energy bills – and more wear and tear on your HVAC system.
  3. A more comfortable home
    An unfinished crawl space affects your home’s everyday comfort. Are your floors cold? Is your main living area significantly cooler than an upper level of your home? Sealing and insulating your crawl space will help. After a short time in an uncomfortable home, you’ll wish you’d invested in upgrading your crawl space.

Traditionally, insulation has been used to create a thermal barrier around a building. Very little was known about building science and the way a building consumed energy.

There is a lot to know about building science. There are key components that, when understood, make saving energy and increasing building comfort much easier.

Much of building science focuses on airflow. Improper airflow can affect on the health and safety of the building residents. It can also cause mold growth, spread pollutants and more. Controlling airflow increases the efficiency of a building, reduces stress on HVAC systems and controls indoor air quality.

There are a few key conditions that affect airflow (courtesy ENERGYSTAR.gov):
  • Controlled versus uncontrolled airflow
    • Controlled airflow is generated by mechanical devices. The purpose of controlled/mechanical airflow is to ventilate a building or distribute conditioned air evenly throughout a building. Sources of controlled airflow are ventilation systems, fans and HVAC systems.
    • Uncontrolled airflow is airflow is the result of unplanned gaps, an aging building and other structural issues. Uncontrolled airflow works against the “energy plan” of the building, and causes the HVAC system and other mechanicals to work harder to maintain the indoor environment.
  • Air pressure from wind, heat, fans and duct systems.
    • Pressure differences in a building are caused by one of three things:
      • Wind blowing against a building, causing pressure differences between one side of the building and the other.
      • Heat affects air pressure. Heat naturally rises in a building (called stack pressure or stack effect). The amount of pressure depends on the temperature difference between the inside and outside of the building, as well as the height of the building.
      • Fans (particularly exhaust fans and HVAC air handlers) can contribute to pressures changes. This could be through leakage in the building envelope or the ducting or an imbalance in the supply and return ducts.
      • Duct leaks. When ducts leak to the outside of a building, air infiltration rates can increase by as much as 300%.
  • Holes and pathways
    • Uncontrolled airflow into a building resulting from penetration points in the building envelope. Reducing the number of holes in the building reduces the amount of uncontrolled airflow.

These are all important things to consider when improving energy efficiency of an existing home or commercial space, or during the building process.
