"Koala helped me to understand the science of my attic insulation and airflow, and they were very professional and friendly from the owner to the installation crew. If I noticed a problem they were quick to address it, and they thoroughly cleaned up after the job was finished. Air sealing an attic is widely recognized as beneficial to the home so I am glad they offered that. The need for active vs passive ventilation is controversial enough that I did not add the solar attic fan. I think testing the inflow of air at the eaves by smoke pen or some other method and demonstrating the results should be standard practice, and they did that for me when asked."

Insulation FAQs, answered by experts

Minimal, mainly occasional checks for damage or mold in extreme conditions.

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.
