Frequently Asked Questions

What Is an R-Value?
Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.

Why is insulation important?
Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior.

To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.

How much will I save by insulating the walls, ceilings and floors of my home?
How much you can save depends on the access you have to your insulating surfaces. You may be able to reduce your energy bills from 10% to 50% by either increasing the amount of thermal insulation in your existing home or purchasing additional insulation when buying a new home.

The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use. Energy conserved is money saved, and the annual savings increase when utility rates go up. Insulation upgrades also add to the value of your home.

How much insulation do I need in my home?
SPS Insulation team can schedule a FREE Estimate to go through every area of your house and give you a professional recommendation.

You can personally check attics, floors, celings, walls to determine the amount of insulation already installed. The U.S. Department of Energy recommends home insulation R-values based on where you live. These recommendations are detailed for various sections of the home including walls, ceilings, and basements.

Why hire a professional insulation contractor rather than a general contractor?
Proper installation is essential for insulation to perform properly.
Professional insulation contractors have access to a wide variety of training, are familiar with local codes and regulations, and can offer guidance about the type and amount of insulation to be used. See what our clients say about us.
