Attic Insulation Batt Vs Blown

That makes it fast to install but costlier than batt insulation.

Attic insulation batt vs blown.

Blown in fiberglass creates a seamless blanket in your attic. It is sold in bags and made of materials that are of varying degrees of recycled. I don t know about that but it s a common insulation material that works much better in the blown form than in batts. Sloppy people aren t suited for this job.

The biggest disadvantage of batt insulation is that it does not fit well in non standard spaces. The photo above shows an attic insulated with blown cellulose. Blown in insulation is much easier on installers. That s because blown insulation is great at filling the gaps and giving you a good complete layer of insulation.

When insulating an attic space many homeowners ask us which is better blown in or batt insulation. The answer is it depends. We use both blown in and batt insulation depending on the situation at hand. Blown insulation is accomplished by blowing out chunks of either fiberglass or cellulose from the hose of a blowing machine.

Fiberglass insulation is available in blown in form and so is cellulose which is referred to as loose fill cellulose. Current energy standards recommend the installation of a first layer of craft faced moisture barrier fiberglass batt. Batt insulation is that it is a form of loose fill insulation as opposed to a flexible blanket. Notice how you don t see any of the ceiling framing down at the ceiling level.

Often times a combination of the two is ideal. Instead of cutting and stapling rolled up layers into place they get to spray the insulation where it needs to go. The maximum rating of batt insulation is around 4 2. Batts must be cut tightly and you can t have gaps.

Blown in varieties however typically reach a peak of around a 2 8 r factor. Both blown in and batt roll insulation can be installed in different areas of a home including the attic and the walls. The thermal performance of fiberglass insulation is directly related to its ability to trap and maintain very small pockets of air. Depending on the material of the insulation the installation method may vary slightly.

The first difference in blown in vs. You also don t see any gaps that allow you to see all the way down to the ceiling drywall.
