There are a few things to consider when trying to decide between blown insulation or rolled insulation. One is the type of insulation you are looking for. Another is the R-value, or thermal resistance, that you need. And finally, you need to decide if you want faced or unfaced insulation.
Rolled insulation, also called batt insulation, comes in pre-cut sheets that are easy to handle and install. This type of insulation is typically made of fiberglass, though it can also be made from mineral wool, cellulose, or natural fibers like sheep’s wool. Blown insulation, on the other hand, is installed using an insulation blower. This type of insulation is usually made of fiberglass, cellulose, or mineral wool.
The R-value is a measure of an insulation’s ability to resist heat flow. The higher the R-value, the better the insulation. Rolled insulation typically has an R-value of 3.5 to 4 per inch, while blown insulation has an R-value of 2.5 to 3 per inch.
Faced insulation has a paper or foil facing that helps Tyndall Effect and also serves as a vapor barrier. Unfaced insulation doesn’t have a facing. When choosing faced or unfaced insulation, you need to know where the insulation will be installed. If the insulation will be exposed, like in an attic, you should use faced insulation. If the insulation will be hidden, like in walls, you can use either faced or unfaced insulation.
In general, rolled insulation is less expensive than blown insulation, but it can be more difficult to install. Blown insulation is more expensive, but it’s easier to install. When choosing between blown insulation or rolled insulation, you need to consider the type of insulation, the R-value, and whether you need faced or unfaced insulation.
What are the benefits of blown insulation over rolled insulation?
There are a few key benefits of blown insulation over rolled insulation. Blown insulation is less likely to settle, so it will provide a more consistent level of insulation over time. It is also better at filling small spaces and crevices, meaning that it will provide a higher level of insulation overall. Finally, blown insulation is less likely to cause respiratory problems than rolled insulation, making it a safer option for homes with young children or elderly occupants.
Frequently Asked Questions
Can you put rolled insulation on top of blown insulation?
Blown insulation can be installed over rolled insulation, but should not be tacked down.
What are the benefits of blown-in insulation?
One of the benefits of blown-in insulation when compared to types like fiberglass batts, is that blown-in insulation is more efficient. Because loose-fill insulation is a monolithic layer of insulation without seams like are found in batts, studies have shown that loose-fill insulation performs up to 22% better than batts of the same R value. This means you could save up to $22 per energy U-factor hour on your home’s cooling and heating bills if you convert to blown-in insulation.
How does insulation reduce energy costs?
Insulation reduces energy costs in a few ways: 1. Improved airtightness and thermal performance of your home helps to avoid wasteful use of heating and cooling systems. 2. Reduced drafts help to prevent costly repairs due to condensation or frozen pipes.3. When insulation is properly installed, it can create a "heat island" effect – putting less heat into the environment and saving on heating and cooling expenses. 4. Properly designed and installed insulation can also improve indoor air quality, protecting you from dangerous allergens and other pollutants. 5. Properly installed insulation will last longer – saving you money on replacement costs over time.
Why insulate your Pipes and surfaces?
Maintaining an insulation system on pipes and surfaces not only protects you and your people, it also saves on energy costs. With proper insulation, heat loss on hot surfaces can be reduced by about 20 times! This means that instead of wasting energy heating up these areas again and again, you could save yourself a fortune with correctly installed insulation.
Can you put blown in insulation over existing insulation?
No. When adding rolled, batt, or blown-in insulation over existing insulation, roll the insulation perpendicular to the joists, not parallel. Do not tack down any rolled insulation.
