This isn’t just insulation, it’s also an amazing sound-deadening addition to any walls where you want to keep sound in or out. I’m using it in my basement renovation to keep the the furnace and laundry sounds out of the new rooms.

Not wide enough
Tedious width size since house openings are 24" width. A lot of cutting.

Calculator on website is wrong
The calculator supposedly will give you the amount you will spend for insulation needed once you put in the the square footage. However, it multiplies the square footage times the price of one pallet (24 bags). One bag covers about 29 sq. ft. and one pallet (24 bags) will cover about 705 square feet. That means I will pay $925 (as of 8/9). If you use the calculator and enter 5 sq. ft. x 6 sq. ft. which equals 30 sq. ft. the price will be over $27,000! Please don't trust the calculator. Do your own math until the website administrators fix it.

    Excellent product. I bought the saw that was linked with the insulation and it does an excellent job of shaping and cutting the batt. Very easy to squeeze and place between the wall studs and behing the wires crossing thru the studs. Light to handle and move around
