High performance, innovative InsulPure™ fiberglass insulation is thoughtfully engineered, produced, and shipped. It won’t settle, accumulate moisture, or lose its R-value over time. Why? InsulPure utilizes a more efficient binder with improved mechanical properties: long-lasting thermal performance and reduced noise levels are built-in.


InsulPure recovers quickly—open a batt, roll, or board and the insulation returns to full shape faster. So it’s easier to handle, to cut, and to place. With no additives or dyes, InsulPure is the color inherent to its fibers—white. The new binder formulation also ensures there is no discernible odor. 


InsulPure is also less dusty. That means minimal installation mess and faster worksite cleanup. By working to reduce energy and water during manufacturing, we continue our commitment to zero waste production. Highly compressed packaging ships efficiently from strategically located distribution centers. 

User-friendly and earth-friendly, InsulPure is UL-validated formaldehyde-free, and also meets the GREENGUARD Gold standard for VOC emissions.
