Affordable Insulation is a full service insulation contracting company for existing homeowners to find ways to improve the effectiveness in reducing home energy consumption. We specialize in drill-n-fill to exterior walls where no insulation exists, re-insulation of attics to increase R-value and garage door insulation kits.

"Used Affordable Insulation to blow in fiberglass insulation into attic above 3 car garage. They were quick to reply to my initial inquiry and follow up questions. Marc had the estimate to me the same day I contacted them. Their estimate was much more affordable (pun intended!) than another quote I received. I was very pleased with their number and was ready to hire them. The team of Jason, Jason, and Daniel were courteous, friendly and professional. They called ahead and showed up as scheduled. They made quick work of the job. The job came out looking great. Insulation depth was a couple inches deeper than expected so was pleased about that as well. They ensured no insulation was in the overflow drain pans of water heater or AC since that could clog the overflow drains causing them to backup. They cleaned up all excess insulation that had fallen into the garage. Attention to detail was superb. I highly recommend Affordable Insulation."

Insulation questions, answered by experts

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.

The R-value is a rating that measures the insulation’s thermal resistance (in other words, how well it insulates). For most pipe insulation, the R-value will fall between one and five. The higher the R-value, the more protection for your pipes. All pipe insulation materials should have an R-value listed in the product description or on the product label.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.
