Are you looking to add insulation to your attic? Installing attic insulation over existing insulation can be a tricky process, but with the right materials and techniques, you can ensure that your attic is properly insulated and energy-efficient. Here's what you need to know about installing attic insulation for maximum efficiency. When installing attic insulation over existing insulation, it's important to use uncoated rolls. This will ensure that the insulation is able to breathe and won't be damaged by moisture. If you can't find uncoated rolls, you can simply pull out the kraft (vapor-retardant) paper without losing much insulation.
You should not fix the rolled insulation in place. To begin, bring the fiberglass insulation up to the top of the joists. To do this, use an insulator without a coating and without a paper moisture barrier. Once it's level with the top of the joists, you can add more insulation by placing it at a right angle to the joists. It must also be a material without coating and without a vapor barrier. The EPA recommends 12 inches of insulation or more in many parts of the country.
If you're insulating floors that have a small space or an unheated basement at the bottom, install the insulation with the vapor barrier facing upward, toward the heated spaces at the top. These wire rods hold the insulation and keep it in place. The most common types of attic insulation are loose blown cellulose (R-3.5 per inch), loose blown fiberglass (R-2.5 per inch), or fiberglass blocks (R-3.2 per inch). The table below shows the approximate thickness of each type of insulation you should ideally have in the attic. No matter where you live, having adequate attic insulation is essential for staying comfortable and controlling energy bills. Installing attic insulation over existing insulation is a great way to ensure that your home is properly insulated and energy-efficient.
Tips for Installing Attic InsulationWhen installing attic insulation, there are several tips that can help make sure you get it right:
- Make sure to use uncoated rolls so that your insulation can breathe.
- Bring fiberglass insulation up to the top of the joists.
- Install with vapor barrier facing upward towards heated spaces.
- Use wire rods to hold the insulation in place.
ConclusionInstalling attic insulation over existing insulation is an important step in making sure your home is properly insulated and energy-efficient.
With these tips and techniques, you can make sure that your attic is properly insulated and ready for any season.
