Insulation

Properly insulating your home will not only help reduce your heating and cooling costs but also make your home more comfortable. The insulation in your home provides a resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs. This resistance to heat flow is measured in terms of its thermal resistance or R-value.

Heat flows naturally from a warmer to a cooler space. In the winter, this heat flow moves directly from all heated living spaces to adjacent unheated attics, garages, basements, and eventually outdoors. Heat flow can also move indirectly through interior ceilings, walls, and floors—wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house.

To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Properly insulating your home will decrease this heat flow by providing an effective resistance to the flow of heat.

We always highly recommend properly air sealing your home before having insulation installed. In order to reach the intended R-value you are seeking, air sealing must be first. Without sealing the leaks in your home first, the effective R-value of what is installed is often only 70% of its intended value, causing you to spend money that is not working for you. This will increase the return on your overall investment exponentially. To learn more about the value of air sealing, please see our air sealing page or read the following document from Energy Star.

The Home Energy Solution:

Home Energy Solutions of the Triad will always recommend installing insulation the proper way...with air sealing performed first. Case in point: When you go out in 40 degree weather with a sweater on, you are usually fairly warm. If you lift your sweater from your body and allow air between you and the sweater, the warmth you felt is gone. You still have the sweater on (insulation), but subjecting air flow to the equation renders the sweater obsolete.

We always adhere to NC building code and that code currently states that attics should be insulated to an effective level of R-38 and unconditioned crawlspaces and basement at a level of R-19. Only in the most drastic of cases will we recommend exceeding these levels; in fact, installing more than the level of building code will often create a diminishing return on your investment.
