"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Insulation questions, answered by experts

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

Yes. You should insulate behind shower walls to help stave off heat loss. In other words, it’ll keep the shower or tub from getting too cold. Nothing ruins bath time like stepping into a freezing cold bathroom. Not insulating and air sealing the walls behind the shower allows heat to escape easily, which opens the area up to the elements. 

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.
