Fiberglass Mat Facers for Mineral and Foam Insulation
As a leading manufacturer of technical textiles, we offer a wide portfolio of Evalith® Fiberglass Nonwovens. Our products are engineered to meet the high-performance demands of insulation facers. We can adapt our production to meet the diverse specifications of our customers. Whether it's area weight, color, glass fiber thread reinforcements, or mineral coatings, we deliver precision and flexibility. To combine technical excellence with sustainability, we have also developed innovative binder systems, including bio-based and formaldehyde-free formulations.
Our Evalith® Glass Nonwovens combine various properties like mechanical strength, thermal stability, and excellent surface coverage. They ensure long-lasting performance in both mineral wool and foam insulation which makes them a reliable choice for insulation in residential and commercial construction, as well as in technical applications.
Mineral wool insulation requires facers that perform reliably under heat
and pressure. Evalith® Fiberglass Nonwovens support efficient processing and ensure consistent results.
Key Performance Criteria of Evalith® Fiberglass Mat
- Reliable calorific value
- Dimensional stability during processing
- Strong adhesion to mineral wool
Foam insulation boards require facers that ensure durability throughout the building lifecycle. Evalith® Fiberglass Nonwovens support reliable installation and long-term performance in modern construction environments.
Key Performance Criteria of Evalith® Fiberglass Mat
- High stability for foam (e.g. PU or PIR) lamination
- Good bleed-through resistance during coating
- Beneficial surface tension for consistent foam structure and improved bonding
Anne Schäfer, Portfolio Manager
"Our extensive and highly adaptable product portfolio allows us to meet a wide range of customer needs. Through lifecycle assessments, we provide transparency and help our partners make more sustainable choices across the entire value chain."
What is a Fiberglass Mat?
A fiberglass mat (also called glass veil or glass nonwoven) is a flat fabric composed of chopped fiberglass oriented in a random pattern and bonded together. Originally invented to replace cardboard in waterproofing membranes, fiberglass mats have long since conquered additional applications such as commercial and residential construction, energy storage and automotive. Fiberglass mat can be tailormade to fit the properties the end applications require by adjusting for instance the fiberglass (glass type, fiber sizing, fiber length, fiber diameter, fiber mixture), the binder systems, the mat thickness, and the mat density. Fiberglass mat is sold in rolls of various widths and lengths. Most of the glass fiber mats manufactured worldwide are produced on similar (but not identical) machines to those used in the paper industry.
