Compared to properly installed fiberglass batts that achieve a value of R-11, HP Blow-in-Fiberglass insulation in a 2x4 wall will achieve a value of:

A. R-15
B. R-1
C. R-21


Sagot :

To understand the comparison between the insulation values of the two types of insulation provided, let's carefully examine the effective insulation values:

1. Fiberglass Batts:
- The fiberglass batts, when properly installed, achieve an insulation value of [tex]\( R-11 \)[/tex].

2. Blow-in Fiberglass Insulation:
- For the blow-in fiberglass insulation in a 2x4 wall, we need to compare the provided options: [tex]\( R-15 \)[/tex], [tex]\( R-1 \)[/tex], and [tex]\( R-21 \)[/tex].

Given the options, we see that Blow-in Fiberglass insulation can achieve a value of [tex]\( R-15 \)[/tex]. Hence, in the context of a 2x4 wall, this is the applicable value for the insulation in question.

Therefore, compared to the properly installed fiberglass batts with an [tex]\( R \)[/tex]-value of 11, blow-in fiberglass insulation achieves an [tex]\( R \)[/tex]-value of 15.
