Are Knauf Insulation products formaldehyde-free?
Most of our fiberglass insulation products are made using our patented ECOSE Technology, a bio-based and sustainable chemistry that replaces the phenol formaldehyde (PF) binder traditionally used in fiberglass products. This binder holds our fiberglass material together, giving it its shape and brown color. Products using ECOSE Technology are formaldehyde-free.

What is a simple way to calculate mechanical insulation requirements?
Easily calculate the required mechanical insulation with the NAIMA 3E Plus® FREE software. Determine the right insulation thickness necessary for your project. Thickness is one of the most important factors in the effectiveness of a mechanical insulation system. And without the right tool for the job, determining the right thickness of fiberglass insulation for an application can be challenging.

What is the payback period on insulation over the life cycle of the building (ROI)?
The payback period is the time it takes to recoup the investment made in insulation. The simplest way to determine the payback period is to take the investment and divide it by the annual energy savings. The average homeowner saves an average of 11% on their total energy bill.
What are the recommended temperature ranges for pipe insulation?
Earthwool 1000 Pipe Insulation can be used on piping systems that operate between 0°F and 1000° F.
What does it take to get a grade 1 install?
