Understanding the Elements

Air Tightness.png



Floors, walls, and ceilings are the largest source of a home’s air leakage, accounting for more than twice as much leakage as windows and doors combined.

Air constantly moves from high to low pressure, finding every penetration into and out of your home.  Proper insulation means lower utility bills and a more comfortable living space.

Noise Control.png



In the county, we love the sound of freedom as we watch that Pax. River jet fly over.  We love our neighbors and their dogs.  We love the sound of our kids practicing on the drum set their grandparents bought.  Proper insulation helps us to love these things even more as it reduces exterior and interior noise.

Moisture in the home is everyone’s concern.  When insulating, consider adding a vapor retarder that reduces the risk of mold and mildew, while improving air quality.

What does insulation really do?

A well-insulated home is one of the most cost-effective ways of saving energy while, also, helping to create an acoustically comfortable environment and more valuable home. Heat is a form of energy — it always seeks a cooler area — flowing outward in winter and inward in summer. By reducing heat flow, a properly insulated home uses less energy in winter for heating and less in summer for cooling. Insulation is also an excellent sound absorber. Proper insulation helps to reduce the transmission of sound from other rooms or from the outside. Sound transmission is noise that travels from room to room — or from home to home — such as jet flyovers, washers, dryers, heating and air conditioning systems, drum sets, TV’s, etc. Adding insulation to your home, adds value.

How do I know if my home has sufficient insulation?

Some indicators you do not have sufficient insulation are: hot or cold spots/rooms even though heat or a/c is running, home is built before 2000, insulation in attic is less than 10" high.

What does 'R Value' mean?

Insulation is identified and labeled by R-value. “R” stands for resistance to heat flow. The higher the R-value, the greater the insulating power.

What areas of my home should be insulated?

Insulation is not just for ceilings and walls. There is an insulation for every conditioned and unconditioned space in your home. Consider insulating knee walls, perimeter of your slab, crawl spaces, etc.

They were very professional and timely getting us a fair estimate, getting us on the schedule, and doing a great job. Highly recommend!!! Thanks guys.
