Attic and Floor Insulation

​While your attic may be a good storage space for old clothes and toys, it is also the place in your house where you probably lose the most energy – and money – due to poor insulation. That is what makes upgrading attic insulation one of the most popular energy-saving improvements available.

What's Your Attic Insulation's R-Value?

While your attic may be a good storage space for old clothes and toys, it is also the place in your house where you probably lose the most energy – and money – due to poor insulation. That is what makes upgrading attic insulation one of the most popular energy-saving improvements available.

Insulate Your Attic For Winter And Summer

While some attics aren't insulated at all, most attics are poorly or improperly insulated. So while you may think that your own attic isn't an issue because it has some insulation in it, do you know if it's enough insulation? The U.S. Department of Energy recommends attic insulation to be between R-49 and R-60 (equal to a minimum of 16 inches of fiberglass insulation) depending regional climate – but most homes have attic insulation with an R-value as low as R-19.

Seal Air Leaks Before Adding Attic Insulation

Attic insulation isn't just to keep warm air in during cold seasons. On hot summer days, insulation will prevent the hot air in your attic from seeping into your cooled living areas and making your air conditioner work harder.

​Air Ventilation

Adding attic insulation is the second step in a two-step process – the first step is air seating (i.e. sealing air leaks). Air sealing will prevent the conditioned air in your home from leaking into the attic. This air leakage is a huge waste of energy and money in many homes, and Green Collar Crew can work with you to prevent it. Using caulk, expanding foam or other sealants, we will make sure that all the cracks, gaps and holes are sealed so your attic insulation can work properly.

Keep Existing Attic Insulation

​Your current attic insulation doesn't necessarily have to be discarded in order to put new insulation in your attic. As long as it isn't wet, moldy or too compressed, it can be put back into place after the attic has been sealed and ventilated, before new insulation is added.

Go With Experience

Our team has air sealed and insulated thousands of attics. First we'll assess your attic to see how much air sealing is required, and which type of insulation is recommended for your attic.

Start With an Energy Inspection

Having proper insulation can help increase your comfort, save energy, and improve your home's safety and durability. But the first step is to schedule an energy inspection to find out exactly what home improvement work is recommended for your home. Our certified energy auditors serve the Charlotte, North Carolina area.
