Q: Is doubling up insulation a good idea?

• <div><p>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.</p></div>

Q: What benefits does a professional installation provide?

• <div><p>Improves water efficiency, reduces oversight, and enhances landscape health.</p></div>

Q: What is the life expectancy of wool insulation?

• <div><p>Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years. </p></div>

Q: How do area size, material thickness, and preparation requirements impact installation expenses?

• <div><p>Costs depend on area size, material thickness, and site preparation needs.</p></div>
