Insulation FAQs, answered by experts

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

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.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

Minimal, mainly occasional checks for damage or mold in extreme conditions.
