St. Louis Attic Insulation Contractor

The most cost effective way to improve your homes energy efficiency is by installing attic insulation. Attic insulation can dramatically reduce your energy costs throughout the year. Without sufficient attic insulation your home can lose nearly 40% of the conditioned air your HVAC system generates.

How does attic insulation work?

In the winter months, warm air from a homes furnace rises to our ceilings and passes through into the attic space. This air then moves up and out, through roof ventilation. In the summer months, our roofs radiate hot air downward through our ceilings, and into the living space causing HVAC systems to run excessively.

This loss of energy causes our HVAC systems to work much harder to make the living space comfortable. Attic insulation is simply a barrier that stops the flow of thermal energy through our ceilings each season.

Do I have enough insulation in my attic?

Attic insulation performance directly corresponds with the depth at which it is installed. The best way to determine if you have enough insulation in your attic space is to look at the material you have and measure its current depth.  If you are able to see the ceiling joists in your attic space, you can definitely benefit from increasing your attic insulation.

According to today's energy efficiency standards, and due to our extreme temperature variances, the insulation in our attic space should be at a minimum R-Value of 38.

Until recently, the most common attic insulation material installed was fiberglass. Fiberglass insulation typically carries an R-Value of 2.5 per inch installed. This means that if your attic space is insulated with fiberglass, it needs to have more than 15" to be at its maximum efficiency. Most homes that have fiberglass insulation installed typically have 4-6 inches.

A good option to improve the energy efficiency of your home is to apply blown cellulose over the surface of your existing insulation. Cellulose insulation has higher R-Values than fiberglass and the installation process typically takes less than a day.
