Fiberglass Mat for Bituminous Roofing
Fiberglass mats are used as carriers in bituminous roofing applications to provide dimensional stability and tensile strength to a flat roof system. As they do not have a thermal memory, the relaxion time of a fiberglass reinforced roofing sheet is decreased, which makes roof installations more durable and prevents differential movements.
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.
"Did you know that Johns Manville is self sourced in fiberglass and produces fiberglass mat on two continents? Our manufacturing facilities are based in North America - Etowah, TN and Waterville, OH - as well as in Germany - Wertheim and Steinach."
