Insulation FAQs, answered by experts

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

Yes! Outdoor faucet covers work by enclosing the faucet with a thick, insulating material that will keep the faucet warmer than outdoor temperatures. They need to be sealed tightly against the house to work properly, though, so be sure to tighten the rubber strap or drawstring on the insulation cover to best protect your faucets.

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

Energy-efficient homes generally have higher appraisals and appeal to buyers.
