It would fit but would need to be strapped down. It would be a very tight fit or even at an angle but it compresses a lot when bailed like this.

Hi, What color options are there? I am looking for white or yellow. The brown looks like crap....

Asked by Steve September 8, 2019

Answer

The color of fiberglass was a function of the binder used. We recently switched binder type, so product should be white going forward. There may be some old inventory, so I would recommend checking with Home Depot directly. The bio-based binder gave product brown appearance. You are correct in saying that appearance does not affect the performance.

is this insulation CSA approved

Asked by john July 8, 2019

Answer

Hello John, Thank you for your interest in Johns Manville's kraft paper faced insulation. This product does not carry CSA approval as the CSA is associated with the National Electrical Code (NEC). Johns Manville's insulation products do not conduct electricity nor are they intended to be used for electrical applications. Best regards, Doug Fast

Compact to store prior to use. Bundles of 11 batts were small enough to get into the attic through the access hatch. 2 feet by 4 feet is a convenient size to move around in the difficult space.
