Aerospace

At Johns Manville, we thrive on finding solutions to meet and exceed the unique application demands of the aerospace industry – where space and weight considerations play a crucial role. It’s why our wide range of aerospace insulation products not only provide superior acoustical and thermal performance but also can be fabricated to fit precisely within your unique configuration demands. In addition, we offer a range of products that are resistant to extreme heat and with water-repellent characteristics to prevent the dangerous weight build-up of absorbed water. And with our premium line of aerospace insulation products, you’ll find the same superior acoustical and thermal performance at an even lower weight.

JM considers the end-use application in the design and creation of every aerospace insulation product we engineer. It’s why Original Equipment Manufacturers and fabricators depend on us to save them time and money while delivering consistent performance no matter what the application.
