Insulation questions, answered by experts

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

There are two places where you should not place foam insulation: around electrical boxes or near lightboxes. The foam insulation could get inside the electrical boxes and damage the wiring. Spraying foam too close to a lightbox creates a potential fire hazard; it could also cause damage to the light.

When you insulate ductwork, you help protect the air moving through the system from external conditions and keep it sealed within the ducts. This makes your HVAC system more efficient since it doesn’t have to work as hard to heat or cool your home. Insulation can help lower your energy bills and prevent problems like condensation and mold formation inside your ducts.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

Whether or not you need to insulate exposed ductwork depends on state and local building codes. There is no national requirement for duct insulation. Even if your local codes don't require it, duct insulation can be useful to increase the efficiency of old, thin, or flexible duct materials. Ducts should also be insulated in basements and ceilings to avoid condensation.
