A Contractor’s Guide to Explaining Home Insulation

September 2, 2014

As contractors, you know what’s best for your customers and they often look to you for advice. However, homeowners may be confused by the insulation process or concerned with the cost of insulating certain rooms in their house. When explaining your insulation plans, let them know which rooms are a must to insulate and why.

Areas of the Home to Use Blown-In Insulation

Insulate Floors, Walls and Crawlspaces with Loose-fill Insulation

From the homeowner’s perspective, some rooms may seem unnecessary to insulate. They may not understand that if areas are uninsulated or underinsulated, expensive air is allowed to escape from the home. In turn, the home’s air conditioning or heating unit is forced to keep running, wasting energy and money. At Capitol Machine, we recommend using a loose-fill insulation machine to seal the following essential areas of the home.

Insulate Exterior Walls

For optimal insulation, exterior walls must be insulated to create a thermal barrier between the home and the outdoors. This includes attached garages. According to the North American Insulation Manufacturers Association (NAIMA), “Sections sometimes overlooked are walls between living spaces and unheated garages or storage rooms, dormer walls, and the portions of walls above ceilings of adjacent lower sections of split-level homes.”

Attic and Basement Insulation

Insulate Attics and Basements with Loose-fill Insulation

The attic is one of the most common and important areas of the house to insulate. The Insulation Institute reports that 25 percent of heat escapes through the roof of an uninsulated home. It is imperative to insulate between floor joists, behind knee walls, the attic hatch, the wiring holes, the plumbing vents, open soffit, recessed lights and the furnace flue. Fiber glass, cellulose and mineral wool are recommended blown-in insulation types to tightly insulate the attic.

Attic insulation helps save energy costs and the need for future repairs, while increasing comfort throughout the entire home. The benefits of insulating the basement may be less obvious. Basements are typically cooler because they are below ground. They can contribute to heat loss and be an uncomfortable living area when a home is not properly insulated. If homeowners wish to turn their basements into a playroom, living room or gym, basement sidewalls, floors and ceiling should be insulated.

Interior Floors, Walls and Crawlspaces

Floors, walls and crawlspaces within the home are commonly overlooked, but they do matter. Insulating the interior of a house adds additional protection from energy loss. Another big benefit from insulating the interior is noise control. When contractors insulate underneath the drywall, the Sound Transition Class "STC" rating for the home increases in value, meaning that the amount of sound transmitted between rooms is reduced.
