The tighter the material is the more efficient it will work.
Benefits of blown in insulation in attic.
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.
Picking between fiberglass and cellulose is another layer to consider.
Blown in insulation is much more airtight than standard insulation that comes in the form of rolled batting.
This prevents airflow from entering the attic.
Extend life of hvac equipment.
The blown material is smaller and able to get into tiny cracks and crevices of your attic where air typically leaks through.
Major attic insulation benefits.
When installed on attic floors blown in insulation complements attic ventilation in keeping it cool during hot days thus helping prevent damage caused by hot and humid air.
Small crevices and tight corners are also sealed since the material does not take much space.
Lower cooling costs significantly.
This versatile material can fill in around beams pipes and other uniquely shaped objects and spaces.
If it comes into contact with moisture mold or rot could form depending on which material you decided on.
There are two main types of insulation used in attics.
So maybe by this point you are thinking blown in attic insulation is where it s at.
The insulation can settle and effectively lessens.
