Fiberglass Mat Facers for Gypsum Boards
For gypsum board facers, we provide a variety of coated and uncoated Evalith® Fiberglass Mats. These nonwovens are designed for applications such as fire boards, interior and exterior sheathings. We can adapt our production to meet the diverse specifications of our customers. Whether it's area weight, color 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.
Key Performance Criteria of Evalith® Fiberglass Mat
- Excellent bonding to the gypsum core
- Controlled slurry penetration for consistent quality
- Efficient water vapor transmission rate
- High support of the mechanical integrity
of the board
Gypsum Fire Boards require reliable facers to ensure consistent performance during fire exposure.
Evalith® Fiberglass Mats Facers are engineered for lasting structural integrity ensuring fire resistency under demanding conditions.
Exterior Sheathing Boards require high-performance facers to ensure mechanical integrity. Evalith® Fiberglass Nonwovens Facers are designed to withstand tough environmental conditions such as UV exposure, moisture, and airborne chemicals.
Shaft Liner Boards require durable facers that perform with dimensional stability and resistancy to moisture and thermal stress. Evalith® Fiberglass Mats Facers are critical components in achieving consistent performance in fire-rated shaft wall systems.
Roof Deck Panels require facers that strengthen the panel structure and enhance protection.
Evalith® Fiberglass Nonwovens improve resistance to moisture, mold, fire, and wind uplift - supporting durable and safe roofing solutions in modern construction.
Anne Schäfer, Portfolio Manager
"By offering both coated and uncoated facers, we can manage air permeability – ensuring optimal drying and preventing bleed-through during the production process of board manufacturers."
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.
Rui Ferreira, R&D Director
"Our Evalith® Fiberglass Mats ensure smooth manufacturing and reliable performance in the field. To protect operators and equipment, the facer minimizes fiber and dust formation while providing crack-resistant mechanical strength without brittleness."
Scott Coons, Chief Sustainability Officer
"With formaldehyde- and PFAS-free binder options and recycling content, our Evalith® nonwovens help customers meet environmental goals without compromising on performance."
