Blanket insulation comes in batts or rolls and is the most common type of insulation used in the united states.
Blown in blanket insulation vs batts.
Rolls come in you guessed it rolls you have to cut the material to size.
For instance in 11 25 feet of space batts can achieve an r value of 40.
Bibs is blown in dry and tests have shown that walls insulated with a bibs system are significantly better filled than those insulated using other forms of fiberglass insulation such as batts.
Disadvantages of batt insulation.
The higher the number the better.
It is sold in bags and made of materials that are of varying degrees of recycled.
Batt insulation is that it is a form of loose fill insulation as opposed to a flexible blanket.
Batt insulation is precut in rectangular pieces.
Blown in varieties however typically reach a peak of around a 2 8 r factor.
Compared to blown in insulation batts can reach a resistance rating r factor of over 3 1.
Bibs meanwhile can be as high as r 49.
The thermal performance or resistance to heat flow r factor is not the same when comparing fiberglass batts to blown in fiberglass.
The r factor of blown in fiberglass is usually 2 3 to 2 8 per inch of material.
The answer is it depends.
R value is the measurement of the material s or the insulation s ability to retain heat.
One variation of fiberglass loose fill insulation is the blow in blanket system bibs.
This comparison table reveals bibs can give you higher r values than batts.
No matter the climate in which your home is located insulation makes it a better living space.

We use both blown in and batt insulation depending on the situation at hand.
Reduces air infiltration more than traditional batt type insulation increasing comfort.
The maximum rating of batt insulation is around 4 2.
The first difference in blown in vs.
You can usually obtain an r factor of 3 1 to 4 2 or slightly higher per inch of material with batts.
