"These guys were great. Allen met me at the door with a firm handshake told me what they were about to do and if I had any questions just ask. Leo was just as professional during insulation and got the job done in 3 hours. Dylan kept me up to speed during both projects and was very helpful. Easy reccomendation."

"I highly recommend 3 Insulation. Craig (the owner) was professional, informative, knowledgeable, timely, friendly, and kind. I needed my 1991 house insulation brought up to 2023 standards, and Craig explained in detail what needed to be done.Work included: R-30+ blown fiberglass over both attic spaces Depth Rulers Included Protect the chimney cavity with the insulation cloth included. Air sealing service with materials seals off pipes, wires, junction boxes, fans, etc. Insulate the hatch with R30 batts. Install baffles where needed for proper air flow. Seal Ducts with water based mastic. Seal ducts in drywall with foam sealant. Attic trash and debris cleanup includedAll of the work that Craig and his team completed has now resulted in a much cooler house, which is sure to lower energy bills. Also, Craig was knowledgeable about the rebate process that Duke Energy offers, and he submitted the rebate applications for me. You will NOT be disappointed in the quality and integrity of 3E Insulation. (BTW, this is NOT a paid review.) I am just a very happy customer!"

Insulation questions, answered by experts

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.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.
