Less itchy and better smell

We utilize approximately 12 tractor trailer loads of fiberglass batten insulation per year across our service areas. We've used several other brands in the past, typically those that are pink or yellowish in color, and we specifically switched to Knauf ecobatt due to the odor and extreme itchiness of the other brands. Knauf is far and away the most comfortable fiberglass to touch barehanded while also having little to no odor in comparison.

Easy Choice for Insulation!

Best product on the market for fiberglass batts! Multiple sizes and R values for your projects and with their ECOS spray on the fiberglass you don't have the issues with itchy and dusty installs. Great product for contractors and DIY installers!

Knauf is our Go to choice

As a company, we almost exclusively use Knauf EcoBatt insulation. We love the product and our customers stay happy with our installations. With many R-values and format options, Knauf always delivers the right product for the application!
