What are the best ways to insulate an attic?

• <div><p>Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into <a href="https://www.angi.com/articles/diy-spray-foam-insulation-kits.htm">spray foam insulation</a> or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.</p></div>

Does the paper on insulation go in or out?

• <div><p>If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process. </p><p>A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.</p></div>

Q: What is the best type of insulation for my home?

• <div><p>The <a href="https://www.angi.com/articles/best-types-insulation.htm">best type of insulation for your home</a> will largely depend on your climate and the space in your home you are trying to insulate. Fiberglass, for instance, is excellent for cold climates as it has a high R-value and won&rsquo;t settle much over time; spray foam works well for humid environments as it has excellent moisture-resistant properties. </p></div>

Q: How long does spray foam insulation last?

• <div><p>Spray foam insulation can last up to 80 to 100 years, making your investment worthwhile over the long run. Closed-cell spray foam tends to have the highest durability. Open-cell foam is subject to moisture, which can lead to deterioration. Remember that some spray foams will damage plastic piping, so consult a pro if you have PVC or CPVC pipes. </p></div>

Q: Do freeze-proof faucets need insulation?

• <div><p>Freeze-proof faucets can still benefit from insulation, and they will need covers if you live somewhere with extremely cold winter temperatures. These faucets work with a design that keeps excess water in the pipes inside the home to minimize the risk of freezing, plus a downward slope for any water flowing through the pipes to keep moving. But keeping a cover on all faucets, even freeze-proof fixtures, is the best way to avoid frozen and burst pipes.</p></div>

Q: Does the paper on insulation go in or out?

• <div><p>If you&rsquo;re using faced insulation with paper, face the paper toward the inside of the room during the installation process. </p><p>A good way to remember this is that the paper should face the &ldquo;warm side&rdquo; as it&rsquo;s the vapor barrier, meaning it should face toward where the heat will be coming from.</p></div>

They are very pleasant, amiable and very easy to deal with. Financing was easy with them. You do not need a construction loan. You put down 10% and then nothing else until the end. We are in upstate NY and during the coldest months the heat bill was $187.00. I used the pay $400 in our other...
