Insulation questions, answered by experts

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

If you have intermediate DIY skills and protect yourself with a full PPE suit, chemical-resistant gloves, goggles, and a respirator, you can install spray foam insulation yourself. DIYers have access to two-part spray foam retail kits that are best for use on small projects. Hiring a professional installer is likely the best option if you need to insulate a large space.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

Cellular shades, especially double- or triple-cell varieties, are the most insulating window treatments. Their honeycomb structure traps air in layered pockets, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even more insulation, look for side-tracked cellular shades that seal the edges to minimize air leaks.
