"I only needed part of my attic insulated and brought up to code. I had others try to sell me lots of services I didnâ t need, nor ask for. Denver Insulation came out, measured the area, and gave me a straight forward quote. Work was very fast and professional."

Insulation questions, answered by experts

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.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
