"The team at Dana Insulation is top notch. From Tom in sales to the installation team everyone was courteous and professional. They put down protective plastic on the floors so as not to get any dirt or insulation on the floors. Did a great job cleaning up after the job as well. Thank you very much Dana Insulation!!!! I would definitely recommend this company!!!"

Insulation questions, answered by experts

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.
