Attic blown-in insulation is one of the most common ways to increase insulation in your attic – but it is also advisable to have proper ventilation alongside insulation. Although, attic insulation does not come cheap. Nevertheless, no matter how much you pay upfront or financed the cost for installing the insulation, you will end up getting a return on your investment in a few years due to the energy savings on your bill.
Whether you are going to the do-it-yourself route or planning on contacting an HVAC professional, remember to do your research and thoroughly review all the materials before installing them into your attic. Keep in mind to plan accordingly to avoid further complications.
Here are the steps in installing blown-in insulation in your attic:
- Remove anything stored in your attic.
Having any materials in your attic before installing can impede the process, and, of course, you do not want to get insulating material into any of your household goods and keepsakes, so make sure to keep them in a temporary place.
2. Check around the perimeters of your attic.
Check for any air gaps and other existing problems that could compromise the effectiveness of your insulation. Yes, attic blown-in insulation does a pretty great job getting into all of the small cracks in an attic. However, that does not mean that 100% will fill in every single little gap that exists.
3. Closely pay attention to areas that have contact with hot objects (i.,e. hot water pipes, lighting, HVAC venting)
Take special measures to protect the areas with hot objects so that the insulation does not come into direct contact. Better yet, hire an HVAC professional to put some of these measures to avoid further complications – like, having to run a risk of starting a fire at home.
4. Have a barrier set up.
Protect your home space by ensuring that all doors and other openings are closed so that the spray in the insulation does not travel through the areas around the house. You can use large rolls of plastic sheeting to seal off any openings.
5. Set up the blower.
Setting up the blower is a two-person job. One person will be working on the blower, while the other is in the attic to position the hose where it needs to go. The person at the blower machine needs to keep an eye on it to ensure that everything is working accordingly and keep well-supplied insulation.
6. Let the blower blow.
The person in the attic should have the right equipment and protective clothing: goggles, gloves, long sleeves, pants, and a respirator – be on the side of safety.
Start at the section of the attic that is farthest from the entry point and work your way around to all the remaining areas that will need insulation. As you move the blower hose around the attic, make sure to double-check everything if it is working correctly and that the insulation is adhering to the attic wall as intended.
