Compressed Attic Insulation Fix

For wool types of insulation fiberglass mineral wool steel real wool etc while it varies based on material this is typically much denser than we are able to get it via compression on the job site.

Compressed attic insulation fix.

Yes the compressed r value can be estimated using the following method. Make sure none of these vents are blocked with debris or insulation so that air can easily flow through them. For every x the insulation material is compressed the r value decreases by approximately one half of that percentage or x compressed. These thermal defects undermine the r value of your attic insulation.

Compacted insulation insulation that has been compressed by being walked over or storing boxes on it loses part of its insulation ability. Let s look at an r 19 batt in a 2x6 cavity step 1. Because installing closed cell foam will seal the attic an alternate method of ventilation is necessary.
