About Johns Manville

Back in 1858, Henry Ward Johns applied hot tar to cloth in his basement using a tea kettle and his wife’s clothes wringer, creating the company’s first roofing shingles. During the 20th century, a period of rapid growth caused the company to shift its core business focus to fiberglass insulation. Throughout the 1980s and 1990s, the company went through a few name changes, before finally settling back on Johns Manville in 1997 (the original name having been Johns-Manville). The manufacturer became a subsidiary of Berkshire Hathaway Inc. in 2001 and remains committed to providing innovative and durable products.

Johns Manville Insulation Reviews

Common customer reviews for Johns Manville insulation are that the insulation materials are both easy to work with and to install. The quality of Johns Manville insulation rates high among consumers, with many mentioning the superior noise reduction and temperature control. There are some who feel that, though Johns Manville rolls offer better fitting since you can cut to length, they do not cover quite as much as a pre-cut batt bag of insulation. It is important to always look into consumer reviews of a product before deciding what size and style of insulation you might need.
