How can I keep my house cool without central air?

• <div><p>There are many ways to keep your house cool without central air. In fact, ductless mini-split AC systems are a solid alternative to central AC for situations when you can’t install ducts in your home. If you’re looking for a more budget-friendly cooling solution, consider using window AC units or portable air conditioners.</p></div>

Q: Why is fiberglass considered dangerous?

• <div><p>Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren&rsquo;t many long-term effects, it&rsquo;s still important to take all the proper safety precautions when working with fiberglass.</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: Is fiberglass insulation safe for my home?

• <div><p>While fiberglass is dangerous to work with, it&rsquo;s a perfectly safe material once it&rsquo;s installed. If you&rsquo;re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.</p></div>

Q: How long does it take to insulate a house?

• <div><p>Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home&rsquo;s existing insulation, you have a higher-than-average square footage, or accessibility is limited.</p></div>

William Moore, owner of Patriot Contracting is amazing! Nobody would commit to a complete 1880's home renovation at the height of the pandemic. He figured out relocating a stairwell that 6 other contractors and a structural engineer never got. He and his crew were hardworking, honest, and...
