Three Things You Don’t Know About Fiberglass Insulation
- Loose Fill with Air Sealing – The woven fibers in this type of insulation do not inherently stop airflow. While fiberglass insulation adds r-value it does not keep conditioned air from escaping through penetration points. Combining fiberglass insulation with air sealing prevents conditioned air from escaping the home, helping reduce energy bills and wear and tear on your HVAC system. ENERGY STAR states sealing air leaks and insulating can save a homeowner on their energy bills.
- Blown in Wall System – In new home construction, many contractors choose to install fiberglass batt insulation in wall cavities. The blown-in wall system from Owens Corning takes wall insulation a step further. With this system, loose-fill fiberglass insulation is densely packed into the wall cavity behind a layer of plastic. This fully fills the wall cavity and reduces air gaps that naturally occur around batts. Many contractors take this system one step further by air sealing the wall cavity before installing insulation to increase energy efficiency even more.
- Flash and Batt – The flash and batt system (also known as a hybrid system) combines the best of fiberglass insulation and spray foam insulation in one application. During installation, spray foam insulation is applied to a cavity followed by a fiberglass batt. This system combines spray foam’s air sealing properties and the insulating benefits of fiberglass at a lower price point than installing full spray foam.
