Insulation questions, answered by experts

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

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. 

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.
