Q: Where should I not use spray foam insulation?

• <div><p>There are two places where you should not place foam insulation: around electrical boxes or near lightboxes. The foam insulation could get inside the electrical boxes and damage the wiring. Spraying foam too close to a lightbox creates a potential fire hazard; it could also cause damage to the light.</p></div>

Q: Can I install cellulose insulation without a blower?

• <div><p>It&rsquo;s technically possible to install loose-fill cellulose insulation without a blower, but it&rsquo;s much more time-consuming, tedious, and dangerous. You&rsquo;ll need to wear the proper protective coverings to handle the cellulose after it&rsquo;s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.</p><p>That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they&rsquo;ll rent out the blower at no extra cost.</p></div>

Q: What keeps ice from melting?

• <div><p>When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. </p><p>Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.</p></div>
