What is the best type of insulation to use? This million dollar question is a very valid one with a simple answer: Properly installed insulation. There are many different types of insulation products available in the market place today. Blown-in or loose fill insulation; cellulose or fiberglass insulation; batt or foam insulation; denim or rigid board. Any of these choices will work in most scenarios as long as they are properly installed.
Properly installed insulation means no gaps, no voids and no compression. This type of install can only be achieved by a professional. Just 3-5% in total gaps can lower product efficiency by 50%, so that R-30 attic insulation would function more like R-15.
Make sure the contractor you hire is a licensed insulation company with the Contractor’s State License Board (www.cslb.ca.gov), and that they use their own trained installers. You should also verify how long they have been in business, that they are properly insured and if there have been any complaints reported against them.
I also recommend that you check their credentials. See what types of organizations they belong to and what energy efficient rebate programs they are participating contractors in. This will greatly help you determine whether they are a company qualified to take care of your needs.
Insulation is an unseen, unheard and unnoticed ally in the fight for energy independence. Don’t allow improperly installed insulation to gobble up your comfort and your wallet. Do your research. Ask the right questions. Find a company that stands behind the quality of the install as well as the product.
