What Does Insulation Look Like?

Does your home have enough insulation? While many homeowners understand (at least to a degree) the benefits insulation offers, they aren’t quite as sure what it looks like or where it is in their home. In addition to the attic, your walls and basement or crawl space are probably insulated.

Here are some images of insulation materials that can be installed in both new and existing homes:

What Does Spray Foam Insulation Look Like?

Spray foam insulation (commonly made of polyurethane) is applied wet and expands into thick foam that fits snugly in wall cavities, crevices and gaps. It’s usually white or a similar shade.

The spray foam material can be applied as high-pressure foam (typically used in new construction) or low-pressure foam (usually in re-insulation projects where the walls and drywall are already in place) and is available as open-cell or closed-cell.

Open-cell foam is highly effective at helping absorb sound and is often used in interior walls. Closed-cell foam is denser and more moisture-resistant.

What Does Fiberglass Insulation Look Like?

Made of tiny glass fibers, fiberglass insulation can be installed in many areas of a home. Owens Corning fiberglass is pink, but this type of insulation comes in various other colors, from yellow to white to brown. It’s available in blown-in (top image) and batt (bottom image) form.

Fiberglass insulation can help you reduce your energy bills and maximize the energy efficiency of your home or building, make your home or building more comfortable year-round and reduce noises from outside and inside.

What Does Cellulose Insulation Look Like?

Cellulose insulation is extremely environmentally friendly, made of up to 85% recycled materials. It’s generally gray or brown.

Cellulose insulation has many benefits over traditional fiberglass insulation. It doesn’t pose a health risk, holds R-value well even in extreme cold weather and fills the space better to prevent gaps that let in air.
