• <div><p>An insulated garage door is a great long-term investment if it&rsquo;s within your budget. They save energy and give the door year-round usability.

Q: What is R-value and what is the R-value of injection foam?

• <div><p><a href="https://www.angi.com/articles/what-r-value.htm">R-value</a> stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.</p></div>

Q: How do I dispose of excess insulation?

• <div><p>How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary. </p></div>

Q: How hot is an attic on a summer day?

• <div><p>If the temperature outside is around 90 or 100 degrees with the sun beating on your home&rsquo;s roof, it&rsquo;s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The <a href="https://www.angi.com/articles/what-is-radiant-barrier.htm">radiant barrier</a> reflects the heat entering the attic back upward, keeping your home&rsquo;s temperature more consistent.</p></div>

Q: Is it normal for my attic to be hot?

• <div><p>It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren&rsquo;t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home&rsquo;s structure, including the roof, wood framing, and HVAC system. </p></div>
