What is insulation made out of?

• <div><p>Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.</p></div>

Q: How long does blown-in insulation last?

• <div><p>At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep&rsquo;s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don&rsquo;t run into any issues, such as flooding or mold, that shorten the lifespan.</p></div>

Q: Is ceiling insulation worth it?

• <div><p>Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2. </p></div>

Q: Which floor is warmest in winter?

• <div><p>Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.</p></div>

Q: What is the easiest way to remove insulation?

• <div><p>If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.</p></div>
