Understanding Insulation -- A Beginner's Guide

February 2, 2012 | Blog

When you want to increase the energy efficiency of your home, understanding insulation is a good place to start. Although the winters are mild in Corpus Christi, the evening and morning chill require some heat in the home. It’s also a good time to undertake projects in the area since the weather is cooler, making it more comfortable to work in the attic, where insulation has an important role.

The common element shared by all insulation products is that they provide resistance to temperature change. The term, R-value, refers to the length that the material resists heat. An R-value of 30 can resist temperature change for 30 hours, while R-13 indicates it resists heat transfer for 13 hours.

Batt Insulation

Made from fiberglass, rock wool or natural fibers, batt insulation is among the easiest to add to attics and when you’re remodeling walls. The batts lie between ceiling joists or wall studs. Normally, they’re stapled in place. The R-value of batt insulation depends on its thickness and the material used to make it.

Foam Insulation

Whether it’s applied as a liquid or installed as solid sheets, foam insulation offers some of the best protection to reduce heat transfer. As part of understanding insulation, it’s also helpful to know that some insulation is better at stopping air infiltration as well as resisting temperature change. Foam has the highest resistance to both airflow and heat.

Blown-in Insulation

Made from shredded recycled paper or loose fiberglass, blown-in is a good way to add insulation to existing wall cavities and attics. We greatly prefer the fiberglass insulation over the shredded paper or cellulose type.  The paper has a borate treatment, which helps it to be more fire retardant, but this borate treatment causes dust problems in the home.

Reflective Barrier Insulation

Combining insulation with a radiant barrier reduces the heat load in attics in the Corpus Christi area in the summer. The radiant barrier redirects the heat back through the roof, reducing the heat that penetrates your ceilings. Radiant barriers can reduce air conditioning bills significantly in hot climates.

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.
