When most people hear the word "insulation," they think of a material designed to keep the cold out. While buffering against the cold is one of the things insulation can do, it's important to remember that attic insulation in a warm climate is essential when it comes to protecting your home.
Here are three tips you can use when investing in new insulation for your attic if you live in a warmer climate.
1. Add more insulation in the right places.
Adding additional insulation can be a great way to reduce your energy costs but only if this insulation is installed in the right places. Think about the way heat enters your home. Since the roof is directly affected by the sun's rays, the heat load on your roof is often greater than the heat load on your walls.
In order to keep your home as cool as possible, adding additional insulation to your attic's roof is necessary. By selecting the right location to add insulation, you make your home more impervious to the heat waves that can plague warmer climates.
2. Make sure air conditioning ducts in your attic are inside the insulated envelope.
If your home has air conditioning ducts running through the attic space, you may be losing quite a bit of cooled air before the air even has a chance to travel throughout your home.
The temperature in the areas of your attic that are not insulated can reach 140 degrees in warm climates. If your air conditioning ducts are not inside the insulation envelope (the barrier separating the interior of your home from the exterior), they will be working harder to try and cool your attic space. Doing something as simple as including the air conditioning ducts inside the insulation envelope during installation can save you a significant amount of money on cooling costs in the future.
3. Consider installing continuous insulation in your attic.
Making the choice to install continuous insulation in your attic space can create a tighter insulation envelope, since there are no joints where air can potentially leak in or out. Continuous insulation is also more energy efficient, with twice the R-value per inch when compared to traditional batting insulation.
In addition to these benefits, using continuous insulation could help reduce the thickness of your walls. Since continuous insulation maintains thermal efficiency without the thickness of traditional batt insulation, you can design your insulation to fit the architecture of your home.
If you live in a warm climate, insulating your attic properly is essential. Be sure to insulate the right areas, include your air conditioning ducts in the insulation envelope, and consider continuous insulation to help keep your home as cool as possible.
