Frequently Asked Questions
Q: What is mineral wool with ECOSE Technology?
A: Knauf Insulation mineral wool is manufactured from naturally occurring and/or recycled raw materials, and is bonded using a bio-based technology free from formaldehyde, phenols, acrylics and with no artificial colours, bleach or dyes added.
Q: What is ECOSE Technology?
A: ECOSE Technology is a revolutionary, new, formaldehyde-free binder technology, based on rapidly renewable materials instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability. ECOSE Technology was developed for glass and rock mineral wool insulation, but offers the same potential benefits to other products where resin-substitution would be an advantage.
Q: How does ECOSE Technology work?
A: By converting bio-based materials into an inert polymer through a proprietary process, ECOSE Technology is used to create an exceptionally strong binder.
Q: What is a binder?
A: The ECOSE Technology binder performs the same function as a phenol-formaldehyde binder in conventional mineral wool products; it binds the fibers together while providing the strength, durability and resiliency required by the insulation industry. This revolutionary scientific discovery eliminates the formaldehyde and phenols found in traditional binders used in various industrial processes.
A: At the base of the new binder are plant starches, which turn into an inert polymer during the manufacturing process of our mineral wool.
Q: What has been the response to the new mineral wool with ECOSE Technology?
A: The market response so far has been absolutely overwhelming. Architects are very enthusiastic about the sustainability aspects of this new product and we already see mineral wool specifications in building projects referring to ECOSE Technology. Also, contractors and installers are now specifically requesting our new products from the trade because of the superior handling characteristics compared to conventional glass mineral wool products.
Q: Is mineral wool with ECOSE Technology more expensive?
A: No, Knauf Insulation offers its new product range with ECOSE Technology at the same price as its traditional mineral wool was sold, delivering added value at the same price.
Q: How can I recognize mineral wool made with ECOSE Technology?
A: The products distinguish themselves by colour and packaging. With the new technology the mineral wool colour results in a distinctive natural shade of earthy brown. The ECOSE Technology brand and logo are clearly visible on the new transparent packaging used for mineral wool with ECOSE Technology and serves as your complete assurance that there is absolutely no formaldehyde, acrylic, phenol, dye or artificial colours added in the chosen Knauf Insulation product.
Q: Does the brown colour come naturally?
A: Yes. There are no artificial colours, dyes or bleach added. The natural brown colour appears during the curing process of the mineral wool.
Superior Handling
Q: What do you mean by “superior handling”?
Q: You say the new mineral wool is softer to touch and contains less dust compared with ordinary glass mineral wool. Are precautions against irritation when working with it still necessary?
Q: Why are products made with ECOSE Technology more
sustainable than the comparable standard available products?
- they are manufactured from naturally occurring and/or
recycled materials raw materials and bonded using a
bio-based technology free from formaldehyde, phenols,
acrylics and with no artificial colours or dyes added.
- they contribute to improved indoor air quality of
buildings compared to traditional mineral wool since
there is no formaldehyde or phenol used
- they have the added benefit of using a binder, which
is up to 70% less energy intensive than traditional
binders and thus reduce the impact on the environment
- pollutant manufacturing emissions and workplace
exposures are reduced, and the overall sustainability of
buildings in which they are incorporated is improved
- they are cost competitive with our traditional mineral
wool, facilitating the market transformation to more
sustainable construction.
Q: Why was ECOSE Technology selected, if current products are considered sustainable?
Q: What is formaldehyde and where is it found?
Q: What does “formaldehyde-free” mean?
Q: Is formaldehyde hazardous?
Q: Why is it better to use formaldehyde-free products?
Q: Are specifications being prepared for formaldehyde-free insulation products?
Q: Does formaldehyde contribute to the product performance of mineral wool insulation?
Q: How does mineral wool with ECOSE Technology perform compared to traditional mineral wool?
Q: What testing have Knauf Insulation mineral wool products with ECOSE Technology gone through?
Q: What is the warranty of the mineral wool products with ECOSE Technology?
Q: What do you mean by “improved durability?”
Q: Why is ECOSE Technology not yet used on the entire
mineral wool product range of Knauf Insulation?
