Q: Will pros manage window drafts more effectively than DIY methods?

• <div><p>Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.</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: Do I need a vapor barrier in my basement?

• <div><p>Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces. </p></div>

Q: How long does rockwool insulation last?

• <div><p>Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.</p></div>
