Fiberglass Mat for Ceiling Tiles

Fiberglass mats are used as front and back facers in ceiling tiles to provide mechanical stability to a ceiling and to allow for improved room acoustics.

Ceiling tiles can reduce the transmission of noises and, depending on the fiber structure of the fiberglass mat, the acoustical characteristics can vary. Additionally, fiberglass mats provide an attractive optical appearance to a ceiling when used as front facers.

Portfolio Manager

"Our unique capabilities allow us to offer a fiberglass mat portfolio with different structures optimizing the acoustical properties of the final ceiling tile. In addition, we are able to adjust the surface characteristics and coating formulations of the nonwoven to optimize the coating weight. Johns Manville also offers ready-to-use solutions to be applied without further processing."

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.
