Doorbell Installation questions, answered by experts

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.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
